1/70 “METHOD OF PROCESSING THE PROCESSING OF CHANNEL STATE INFORMATION, NETWORK DEVICE AND EQUIPMENT OF
USER"
FIELD OF TECHNIQUE [001] Modalities of the present invention refer to the field of communications technologies, and, in particular, to a method of processing channel state information processes, a network device and user equipment.
BACKGROUND [002] In the field of radio communications technologies, before, the Transmission and Reception of Multiple Coordinate Points (Transmission and Reception of Multiple Coordinate Points, CoMP to shorten below) is introduced, for each user equipment (user equipment, UE for shortening down) on a carrier, the UE can only be triggered to perform at most a measurement feedback of aperiodic channel status information (Channel Status Information, CSI to shorten below) at a time and a reference feature of CSI is defined, in which a reference resource for reporting aperiodic CSI is correct in a subframe that receives a CSI request and a time interval for CSI reporting is 4 ms. Since only one CSI piece is configured on one carrier at a time, when reporting CSIs, the UE has sufficient capacity to complete measurement and calculation of all CSIs configured by a base station and to report a result.
[003] However, after CoMP technology is introduced, multiple CSI processes can be
2/70 configured for a UE on a carrier, where a CSI process is associated with a channel measurement feature and an interference measurement feature, and the reporting of a CSI piece is associated with a CSI process, for example, processing of multiple aperiodic CSI processes. At that time, there is a problem in which the UE cannot complete the processing of CSI configured by the base station.
SUMMARY [004] The modalities of the present invention provide a method of processing channel state information processing, a network device and user equipment, which are used to solve an existing problem in the prior art that a UE cannot complete the processing of CSI configured by a base station.
[005] A first aspect of the present invention provides a method of processing channel state information processing, which includes:
upon receipt of a first CSI channel status request sent by a first network device, where the first CSI request is used to trigger an aperiodic CSI report, if CSI corresponding to multiple aperiodic CSI processes have not been reported by the user equipment, it cancels the CSI corresponding to a part of aperiodic CSI processes among the multiple aperiodic CSI processes, where each CSI process is associated with a channel measurement feature and an interference measurement feature.
[006] Aperiodic CSI processes are processes of
3/70
CSI for reporting aperiodic CSI.
[007] The cancellation of CSI corresponding to a part of aperiodic CSI processes among the multiple aperiodic CSI processes cancels the reporting of CSI corresponding to the part of aperiodic CSI processes among the multiple aperiodic CSI processes.
[008] The multiple aperiodic CSI processes are aperiodic CSI processes corresponding to the first CSI request. Alternatively, prior to receiving a first CSI request sent by a first network device, the method additionally includes: receiving a second CSI request, where multiple aperiodic CSI processes are aperiodic CSI processes corresponding to the first CSI request and aperiodic CSI processes corresponding to the second CSI request.
[009] The cancellation of CSI corresponding to a part of aperiodic CSI processes among the multiple aperiodic CSI processes includes:
if the number of multiple aperiodic CSI processes exceeds a first threshold, cancellation of the CSI corresponding to the aperiodic CSI process portion among the multiple aperiodic CSI processes.
[010] The first threshold is predefined, or is notified by the first network device, or is notified by the second network device.
[011] The cancellation of CSI corresponding to a portion of aperiodic CSI processes among the multiple aperiodic CSI processes includes:
cancel, according to a priority or
4/70 cancellation, the CSI corresponding to the part of aperiodic CSI processes among the multiple aperiodic CSI processes corresponding to the first CSI request;
or cancel CSI corresponding to all aperiodic CSI processes corresponding to the first CSI request, where the CSI corresponding to all aperiodic CSI processes corresponding to the first CSI request are the CSI corresponding to the aperiodic CSI process part.
[012] Additionally, the cancellation of CSI corresponding to a part of aperiodic CSI processes among the multiple aperiodic CSI processes includes: canceling, according to a priority or cancellation rule, the channel status information from the process processes. Aperiodic CSI among the multiple aperiodic CSI processes corresponding to the first CSI request and the second CSI request; or cancel the CSI corresponding to all aperiodic CSI processes corresponding to the first CSI request, where the CSI corresponding to all aperiodic CSI processes corresponding to the first CSI request are the CSI corresponding to the aperiodic CSI process part.
[013] In another implementation mode, the cancellation of CSI corresponding to a part of aperiodic CSI processes among the multiple aperiodic CSI processes includes:
cancel CSI corresponding to a portion of aperiodic CSI processes according to the number of processes
5/70 aperiodic CSI with corresponding CSI not reported by the user equipment and a CSI process processing capability of the user equipment.
[014] The CSI process capability of the user equipment is a predefined CSI process that processes the capacity of the user equipment or a minimal CSI process that processes the capacity of each user equipment.
[015] Specifically, the user equipment's CSI process processing capability processes N CSI processes per ms, or processes K CSI processes per M ms, where N is a positive number, and M and K are integers positive. The CSI process processing capacity of the user equipment can include multiple levels of capacity, where different levels of capacity correspond to different N values, or correspond to different combinations of M values and K values.
[016] Additionally, the method may also include: reporting the processing capacity of the
User equipment CSI for the first network device or a second network device.
[017] In addition, the method may also include: sending CSIs obtained through measurement to the first network device or the second network device, in which CSI corresponding to the processing of canceled aperiodic CSI processes are replaced by a previous measurement result or are replaced by a pre-established first sequence, and the first pre-established sequence represents the cancellation of CSI processes
6/70 aperiodic via user equipment. The first pre-established sequence is a complete sequence of 0 or a complete sequence of 1.

[019] Aperiodic CSI processes are CSI processes for reporting aperiodic CSI.
[020] The cancellation of CSI corresponding to a part of aperiodic CSI processes among the multiple aperiodic CSI processes cancels the reporting of CSI corresponding to the part of aperiodic CSI processes among the multiple aperiodic CSI processes.
[021] User equipment cancels CSI corresponding to a portion of aperiodic CSI processes out of multiple aperiodic CSI processes when the number of multiple aperiodic CSI processes exceeds one
7/70 first threshold, or cancels CSI corresponding to a portion of aperiodic CSI processes according to the number of aperiodic CSI processes not reported by the user equipment and a CSI process processing capability of the user equipment.
[022] The user equipment's CSI process processing capability processes N CSI processes per ms, or processes K CSI processes per M ms, where N is a positive number, and M and K are positive integers. Alternatively, the CSI process processing capacity of the user equipment includes multiple levels of capacity, where different levels of capacity correspond to different N values, or correspond to different combinations of M values and K values.

DESCRIPTION OF MODALITIES [058] The following clearly and completely describes the technical solutions in the modalities of the present invention with reference to the accompanying drawings in the modalities of the present invention. Apparently, the described modalities are merely a part instead of all the modalities of the present invention. All other modalities obtained by individuals of ordinary skill in the art based on the modalities of the present invention without creative efforts should fall within the scope of protection of the present invention.
[059] In view of the problem existing in the prior art that after CoMP technology was introduced a UE cannot process CSI configured by a base station, the modalities of the present invention provide a technical solution. Figure 1 is a first schematic flowchart of a CSI process processing method according to an embodiment of the present invention. As shown in Figure 1, the method includes the following steps.
23/70 [060] Step 101: Receive a first CSI request sent by a first network device, where the first CSI request is used to trigger aperiodic CSI reporting. Specifically, in the embodiment of the present invention, the first request for channel status information can instruct a user equipment to measure channel status information, and a first request for channel status information can instruct the user equipment to cancel multiple channel state reporting processes, where each CSI process is associated with a channel measurement feature and an interference measurement feature.
[061] Step 102: If CSI corresponding to multiple CSI processes (process) have not been reported by the user equipment for aperiodic CSI reporting, cancel (cancel) CSI corresponding to a portion of aperiodic CSI processes among the multiple reporting processes. Aperiodic CSI. Specifically, aperiodic CSI processes are CSI processes for reporting aperiodic CSI. The cancellation of CSI corresponding to a portion of aperiodic CSI processes among the multiple aperiodic CSI processes cancels the reporting of the CSI corresponding to the portion of aperiodic CSI processes among the multiple aperiodic CSI processes.
[062] In the aforementioned modality of the present invention, after receiving the first request for channel status information sent by the first network device, the UE cancels the CSI corresponding to a part of the CSI processes, through which it solves the existing problem after a CoMP technology was introduced by the
24/70 fact that the UE cannot implement processing of multiple CSI processes.
[063] Specifically, in the aforementioned modality, the multiple aperiodic CSI processes can be aperiodic CSI processes corresponding to the first CSI request. Alternatively, prior to receiving a first request for channel status information sent by a first network device, the method additionally includes: receiving a second request for channel status information, and the multiple aperiodic CSI processes are CSI processes aperiodic, which is not reported, corresponding to the first request for channel state information and aperiodic CSI processes, which are not reported, corresponding to the second request for channel state information.
[064] The processing of the cancellation (cancellation) of a part of aperiodic CSI processes among the multiple aperiodic CSI processes can be conducted in two situations. First, if the number of multiple aperiodic CSI processes exceeds a first threshold, a portion of aperiodic CSI processes out of multiple aperiodic CSI processes is canceled. Second, a portion of aperiodic CSI processes are canceled according to the number of aperiodic CSI processes not reported by the user equipment and a CSI process processing capability of the user equipment. The cancellation of the CSI processes may be the cancellation of the CSI report corresponding to the CSI processes.
[065] In the first situation, the cancellation of part of aperiodic CSI processes among the multiple processes
25/70 aperiodic CSI includes: canceling the CSI corresponding to the aperiodic CSI process part, so that the number of non-canceled aperiodic CSI processes among the multiple aperiodic CSI processes is less than or equal to the first threshold. The first threshold can be a predefined threshold, that is, the first threshold is configured at the base station and the UE in advance when a communications system is pre-configured. Upon receiving a request for channel status information, the user equipment can perform a comparison according to the predefined threshold and the number of unreported channel status information processes. In addition, the first threshold can additionally be notified by the first network device, or notified by a second network device.
[066] In addition, the cancellation of CSI corresponding to a portion of aperiodic CSI processes among the multiple aperiodic CSI processes includes:
cancel, in accordance with a priority or cancellation rule, the CSI corresponding to the aperiodic CSI process portion among the multiple aperiodic CSI processes corresponding to the first CSI request;
or cancel CSI corresponding to all aperiodic CSI processes corresponding to the first CSI request, where the CSI corresponding to all aperiodic CSI processes corresponding to the first CSI request are the CSI corresponding to the aperiodic CSI process part.
[067] In addition, in the above mentioned modality
26/70 invention, the cancellation of CSI corresponding to a part of aperiodic CSI processes among the multiple aperiodic CSI processes includes:
cancel, in accordance with a priority or cancellation rule, the CSI corresponding to the aperiodic CSI process portion among the multiple aperiodic CSI processes corresponding to the first CSI request and the second CSI request; or cancel CSI corresponding to all aperiodic CSI processes corresponding to the first CSI request, where the CSI corresponding to all aperiodic CSI processes corresponding to the first CSI request are the CSI corresponding to the aperiodic CSI process part. In the aforementioned modality of the present invention, the cancellation rule includes any one or more of the following four items:
cancel CSI corresponding to an aperiodic CSI process with a minimum index number or CSI corresponding to an aperiodic CSI process with a maximum index number; cancel CSI corresponding to an aperiodic CSI process that is triggered first or CSI corresponding to an aperiodic CSI process that is triggered last; cancel CSI corresponding to an aperiodic CSI process with the longest time since the last feedback or CSI corresponding to an aperiodic CSI process with the shortest time since the last feedback; and cancel CSI corresponding to an aperiodic CSI process with a higher feedback frequency or CSI corresponding to an aperiodic CSI process with a higher feedback frequency
27/70 low; and [068] CSI corresponding to an aperiodic CSI process with a low priority are canceled first, and the priority includes any or several of the following four items: a CSI priority corresponding to an aperiodic CSI process with a small number of
index is bigger that that in CSI corresponding The one process from CSI aperiodic with an lots in index or a priority in CSI corresponding The one process from CSI aperiodic with an lots in index is bigger that that in CSI corresponding The one
aperiodic CSI process with a small index number, a CSI priority corresponding to an aperiodic CSI process triggered earlier is higher than that of CSI corresponding to an aperiodic CSI process triggered later or a CSI priority corresponding to a process later aperiodic CSI process is greater than that of CSI corresponding to an earlier aperiodic CSI process, a CSI priority corresponding to an aperiodic CSI process with a long period of time since the last feedback is greater than that of CSI corresponding to an aperiodic CSI process with a short time since the last feedback or a CSI priority corresponding to an aperiodic CSI process with a short time since the last feedback is greater than that of the CSI corresponding to a feedback process Aperiodic CSI with a long time since the last feedback, I A CSI priority corresponding to an aperiodic CSI process with a high feedback frequency is
28/70 greater than that of CSI corresponding to an aperiodic CSI process with a low feedback frequency or a CSI priority corresponding to an aperiodic CSI process with a low feedback frequency is greater than that of CSI corresponding to a feedback process Aperiodic CSI with a high frequency of feedback.
[069] In a multi-carrier situation, priority in two dimensions of carrier and CSI process can be considered concurrently, and a CSI process with a low priority is canceled first. At this point, for all CSI processes, CSI process carrier index numbers are compared first, then CSI process index numbers are compared, and a low priority CSI process will be canceled first.
[070] The technical solution of the present invention can be summarized to include three basic solutions:
First, when the UE receives a CSI request, if the UE has received at least one CSI request before, and CSI corresponding to aperiodic CSI processes corresponding to at least one CSI request is not yet reported, and at that time , if the number of all aperiodic CSI processes, with corresponding unreported CSI that include CSI processes corresponding to the recently received CSI request, exceeds a K threshold, the UE cancels processing of a portion of aperiodic CSI processes according to a priority or cancellation rule for each CSI, so that the number of aperiodic CSI processes, which are not canceled, with corresponding CSIs not reported
29/70 is not greater than the K threshold;
Second, when the UE receives a CSI request, if the UE has not received other CSI requests before, that is, a situation does not exist in which CSI processes corresponding to other CSI requests are not yet reported, and at that time, if the number of aperiodic CSI processes corresponding to a recently received CSI request, that is, all aperiodic CSI processes with corresponding unreported CSI, exceeds a threshold K, at which the UE cancels the processing of a portion of the CSI processes Aperiodic CSI according to a priority or cancellation rule for each CSI, so that the number of CSI processes, which are not canceled, with corresponding CSIs not reported is not greater than the threshold K; and
Third, when the UE receives a CSI request, if the UE has received at least one CSI request before, and CSI corresponding to aperiodic CSI processes corresponding to at least one CSI request are not yet reported, and at that time, if the number of all aperiodic CSI processes, with corresponding unreported CSI that include aperiodic CSI processes corresponding to the recently received CSI request, exceeds a K threshold, at which the UE cancels the processing of all corresponding aperiodic CSI processes to the recently received CSI request.
[071] In the aforementioned description, the CSI corresponding to a part of aperiodic CSI processes can be canceled according to the number of CSI processes
30/70 aperiodics not reported by the user equipment and the CSI process processing capacity of the user equipment, where the user equipment's CSI process processing capacity is a predefined CSI process that processes the equipment capacity or a minimal CSI process that processes the capacity of each user equipment. Specifically, the UE's CSI process processing capability processes N channel state information processes per ms, or processes K channel state information processes per M ms, where N is a positive number, and both M and K are positive integers.
[072] For the processing capacity of the UE, the processing capacity of the CSI process of the UE can be divided into multiple levels of capacity according to a factor such as a type of UE, in which different levels of capacity correspond to values different N, or correspond to different combinations of M values and K values. For example, for a first level, N = 1, and for a second level, N = 2; or for a first level, K = 1, and M = 4, and for a second level, K = 2, and M = 4.
[073] In a specific deployment mode, the UE's CSI process processing capability can also be defined for different carriers respectively. For example, for a carrier with a 5 MHz broadband, N = 3, and for a carrier with a 20 MHz broadband, N = 1.
[074] In the aforementioned embodiment of the present invention, the method may also include the following step:
31/70 report, by the UE, the CSI process processing capability of the user equipment for the first network device or the second network device.
[075] In the technical solution, although the UE reports and sends the CSI process processing capability to the network device, to the network device, there are two types of specific processing. First, the base station performs CSI configuration for the UE according to the processing capacity of the UE, whereby it prevents the CSI process configured for the UE from exceeding the processing capacity of the process; and second, the base station cannot be restricted and can still configure CSI processes that exceed the processing capacity for the UE according to actual requirements.
[076] In the aforementioned embodiment of the present invention, when it is predefined that the UE's CSI process processing capacity processes N CSI processes per month, or processes K channel status information processes per M ms, and if the capacity of processing of the CSI processes configured by the base station for the UE process N + n CSI processes per month, or the processing capacity of the CSI processes configured for the UE process K + L CSI processes per M ms. At that time, the UE may cancel, according to a priority or cancellation rule, the processing of an unreported portion of channel status information, which is similar to the method in the technical solution. Specifically, the processing of n * T CSI processes can be canceled (where T is milliseconds to process CSI), or the processing of L CSI processes can be canceled, to achieve
32/70 a purpose in which the processing capacity of the UE can finish processing the remaining CSI processes, which are not reported. For the base station, since the processing capacity of the UE is predefined, or the UE reports the processing capacity of the UE, when configuring CSI processes that exceed the processing capacity for the UE, the base station may come to believe that the UE will cancel the CSI processes that exceed the processing capacity instead of processing the CSI processes, through which they unify the base station and the UE.
[077] In addition, in the aforementioned embodiment of the present invention, the method may also include the following step:
send CSI obtained through measurement to the first network device or the second network device, in which CSI corresponding to the processing of canceled aperiodic CSI processes are replaced by a previous measurement result or are replaced by a first pre-established sequence, and the first pre-established sequence represents the cancellation of aperiodic CSI processes through the user equipment.
[078] Specifically, the first preset sequence is a complete sequence of 0 or a complete sequence of 1, or it is another sequence.
[079] Furthermore, when CSI corresponding to multiple periodic CSI processes were not reported additionally by the user equipment in addition to the CSI corresponding to the multiple aperiodic CSI processes not being reported, the user equipment cancels CSI, which were not reported. reported, corresponding to a
33/70 part of CSI processes. In addition, when the total number of periodic CSI processes and aperiodic CSI processes, which are not reported by the user equipment, exceeds the first threshold, a portion of CSI corresponding to the periodic CSI processes and / or CSI corresponding to the processes of aperiodic CSI is canceled. The periodic CSI processes in this document are CSI processes for reporting periodic CSI.
[080] Corresponding to the aforementioned modality, an embodiment of the present invention further provides a method of processing channel state information processing. Figure 2 is a second schematic flow chart of a CSI process processing method according to an embodiment of the present invention. As shown in Figure 2, the method includes the following steps.
[081] Step 201: Submit a first CSI request to a user device, where the first CSI request is used to trigger an aperiodic CSI report.
[082] Step 202: Receive CSI obtained by user equipment through measurement, in which CSI are obtained after canceling CSI corresponding to a part of aperiodic CSI processes among multiple aperiodic CSI processes when CSI corresponding to multiple processing processes Aperiodic CSIs have not been reported by user equipment, where each CSI process is associated with a channel measurement feature and an interference measurement feature.
34/70 [083] In the aforementioned modality, aperiodic CSI processes are CSI processes for reporting aperiodic CSI. A network device sends the first CSI request to the user equipment and then receives the CSI obtained by the user equipment through measurement, where the CSI is obtained after the cancellation of CSI corresponding to a part of aperiodic CSI processes among multiple aperiodic CSI processes when CSI corresponding to multiple aperiodic CSI processes were not reported by the user equipment, through which it solves the existing problem after a CoMP technology is introduced by the fact that the UE cannot implement multiple CSI processing.
[084] In the aforementioned modality of the present invention, the cancellation of CSI corresponding to a part of aperiodic CSI processes among the multiple aperiodic CSI processes cancels the CSI report corresponding to the part of aperiodic CSI processes among the multiple aperiodic CSI processes, in which CSI corresponding to the processing of canceled aperiodic CSI processes is replaced by a previous measurement result or is replaced by a first pre-established sequence, and the first pre-established sequence represents the cancellation of aperiodic CSI processes through the equipment of user. The first preset sequence is a complete sequence of 0 or a complete sequence of 1.
[085] In addition, in the aforementioned embodiment of the present invention, the user equipment cancels CSI corresponding to a part of aperiodic CSI processes
35/70 among the multiple aperiodic CSI processes when the number of multiple aperiodic CSI processes exceeds a first threshold, or cancels CSI corresponding to a portion of aperiodic CSI processes according to the number of aperiodic CSI processes not reported by the equipment and a CSI process processing capability of the user equipment.
[086] Additionally, the method may also include the following step: send, via the network device, the first threshold to the user's equipment.
[087] In addition, in the aforementioned embodiment of the present invention, the method may further include the following step: receiving the CSI process processing capability reported by the user equipment. The user equipment's CSI process processing capability processes N CSI processes per month, or processes K CSI processes per month, where N is a positive number, and M and K are positive integers. In addition, the user equipment's CSI process processing capacity includes multiple levels of capacity, where different levels of capacity correspond to different N values, or correspond to different combinations of M values and K values.
[088] An embodiment of the present invention further provides a method of processing channel state information processing. Figure 3 is a third schematic flowchart of a CSI process processing method according to an embodiment of the present invention. As shown in Figure 3, the method includes the following steps.
36/70 [089] Step 301: Receive a first CSI request sent by a first network device, where the first CSI request is used to trigger aperiodic CSI reporting.
[090] Step 302: If CSI corresponding to multiple aperiodic CSI processes has not been reported by a user device, cancel processing of a piece of information in an aperiodic CSI process part, in which each CSI process is associated a channel measurement feature and an interference measurement feature, and the information portion of aperiodic CSI processes includes at least one of a channel quality indication, a pre-coding matrix indication, a pre-type indication -coding or a classification indication.
in this modality,
gives modality shown in the figure 1, O Processing a part in part of processes information in
channel state is canceled. Specifically, for a CSI piece, you can include at least one of a channel quality indication, a pre-coding matrix indication, a pre-coding type indication or a classification indication, and the cancellation processing a piece of information in a piece of information for processing channel status information may specifically be unprocessed for processing at least one of the channel quality indication, the pre-coding matrix indication, the pre-type indication -coding or indication of classification. Aperiodic CSI processes are
37/70 CSI processes for reporting aperiodic CSI.
[092] In the aforementioned modality of the present invention, specifically, the processing of which information can be predefined is canceled, or a base station notifies the UE about it, or the UE applies the same to the base station, or it is established in accordance with so the UE reports it to the base station. Specifically, conditions can be established for each piece of information, and it is selected, according to the established conditions, if corresponding information should be processed. For example, it can be established that an IR value is a subset of optional IR values, for example, if IR = 1, it is unnecessary to try other IRs when the CSI process is processed; it can also be established that a PMI value is a subset of optional PMI values, for example, if PMI = {1, 2, 3}, it is unnecessary to try other PMIs when the CSI process is processed; or it is established that the RI value is a subset of optional RI values, and that the PMI value is a subset of optional PMI values, for example, if RI = 1 and PMI = 5, it is unnecessary to try other RIs and PMIs when the CSI process is processed. Definitely, the conditions set can also be predefined.
[093] The information limitation of each piece of information in the present invention is specifically for a situation where processing capacity is limited, and information is added to the CSI configuration base. When the UE has the ability to process all CSI processes, the UE can select to use information
38/70 in the CSI configuration or the limitation information. When the UE does not have the capacity to process all CSI processes, the UE must use the limiting information.
[094] As is selected, according to the established conditions, in the case of processing the corresponding information in the above, the aforementioned modality of the present invention may additionally include a step of:
receiving first cancellation indication information sent by the first network device, where the first cancellation indication information carries a limit value of at least one of the information from the aperiodic CSI processes.
[095] Specifically, similar to the aforementioned modality, when a measurement result is reported, the part of information canceled in the channel status information processes can be replaced by a first pre-established sequence, and the first pre-established sequence represents the fact that the user equipment does not process the information part. The first pre-established sequence is a complete sequence of 0 or a complete sequence of 1, or it is another sequence.
[096] There is another mode, in which one or more types of channel status information are reported using a measured value reported last time. At that time, the method may additionally include:
receive second cancellation indication information sent by the first network device, in which the second cancellation indication information
39/70 are used to indicate the reporting of at least one of the information from the aperiodic CSI processes through the use of a measurement value reported last time.
[097] One embodiment of the present invention additionally provides a method, and the method is a network device method corresponding to the aforementioned modality shown in Figure 3. Figure 4 is a fourth schematic flowchart of a CSI process processing method according to an embodiment of the present invention. As shown in Figure 4, the method includes the following steps.
[098] Step 401: Send a first request for CSI channel status information to a user device, where the first request for CSI is used to trigger aperiodic CSI reporting.
[099] Step 402: Receive CSI obtained by the user equipment through measurement, in which the CSI are obtained after canceling the processing of a piece of information in a part of aperiodic CSI processes when CSI corresponding to multiple aperiodic CSI processes were not reported by user equipment, where each CSI process is associated with a channel measurement feature and an interference measurement feature, and the information portion of the aperiodic CSI processes includes at least one of a quality indication channel, a pre-coding matrix indication, a pre-coding type indication or a classification indication.
[100] Aperiodic CSI processes are
CSI for reporting aperiodic CSI.
40/70 [101] The method may additionally include the following step:
send first cancellation indication information to the user's equipment, where the first cancellation indication information carries a limit value of at least one of the information from the aperiodic CSI processes; or send second cancellation indication information to the user equipment, where the second cancellation indication information is used to indicate the reporting of at least one of the information from the aperiodic CSI processes using a reported measurement value. last time.
[102] One embodiment of the present invention further provides another method of processing channel state information processing. In the method, a network device sends a first request for CSI channel state information to a user device, and the time interval for sending the first CSI request is not less than a first time interval. The first time slot is a predefined time slot, or the method can additionally include: sending a notification message that carries the first time slot to the user device. That is, the network device will not configure CSI for the UE for two successive moments in the first time interval, and will not cause the UE to report for two moments in the first time interval, which, in this way, alleviates the pressure from the EU. Specifically, the first time interval can consist of several successive subframes.
41/70 [103] For the UE, the UE can receive a first request for CSI channel status information sent by a first network device, and assume that a time interval in which the first network device sends the first request channel status information is not less than the first time interval.
[104] Specifically, where the UE assumes that a time slot in which the first network device sends the first CSI request is greater than the first time slot refers to, the UE believes that the first network device it will not send the first CSI request twice in the first time slot, so the UE will not receive the first CSI request again in the first time slot after the first CSI request is received; or the UE receives the first CSI request in the first time slot, but will cancel it. That is, after receiving the first CSI request sent by the first network device, the UE cancels other first CSI requests received in the first time slot.
[105] In addition, the first time slot is predefined, or is notified by the first network device, and the first time slot is W subframes, where W is a positive integer.
[106] The network device in the aforementioned embodiment of the present invention, or another device that communicates with and controls user equipment.
[107] One embodiment of the present invention additionally provides a method of processing the
42/70 channel status information, which includes: a user device receiving a first request for CSI channel status information sent by a first network device, and the user device canceling all CSI requests received in a second time interval before the next CSI report. The second time slot is predefined, or is notified by the first network device, and the first time slot is W subframes, where W is a positive integer.
[108] An embodiment of the present invention further provides a method of processing channel state information processing. Figure 5 is a fifth schematic flowchart of a CSI process processing method according to an embodiment of the present invention. As shown in Figure 5, the method includes the following steps.
[109] Step 501: A user device obtains a CSI process, in which the CSI process corresponds to a CSI reference resource, and in a time domain, the CSI reference resource is a subframe that includes a non-zero power channel status reference signal feature corresponding to the CSI process and / or a subframe that includes a CSI-IM channel status interference measurement feature corresponding to the CSI process, or a time domain, the CSI reference resource is a subframe that includes a ZP CSI-RS zero power channel information reference signal resource configured for the user equipment.
[110] Step 502: The user equipment processes the
43/70 CSI process according to the reference resource of
CSI.
[111] In step 501 above, the subframe of the ZP CSI-RS resource configured for the user equipment is a subframe of the ZP CSI-RS resource, which has a minimum period and is configured for the user equipment.
[112] Alternatively, in a time domain, the CSI reference resource is a subframe that includes an NZP CSI-RS resource corresponding to the CSI process
and / or a subframe that includes one resource from CSI-IM corresponding to process in CSI, O which is specifically: if a period of the resource NZP CSI-RS corresponding to the CSI process be greater than one period of resource of
CSI-IM corresponding to the CSI process, in the time domain, the CSI reference resource is the subframe that includes the CSI-IM resource corresponding to the CSI process, otherwise, in the time domain, the reference resource CSI is the subframe that includes the NZP CSI-RS feature corresponding to the CSI process; or if a period of the NZP CSI-RS resource corresponding to the CSI process is equal to a period of the CSI-IM resource corresponding to the CSI process, in the time domain, the CSI reference resource is the subframe that includes the NZP CSI-RS resource corresponding to the CSI process and / or the subframe that includes the CSI-IM resource corresponding to the CSI process.
[113] The CSI reference feature is predefined. Alternatively, the method additionally includes:
User equipment receives information from
44/70
recommendation in resource in reference in CSI sent by one first device in network in what at information in recommendation in resource in reference in CSI are used to indicate what, on a domain of time, the resource in
CSI reference is a subframe that includes a non-zero power channel status reference signal feature corresponding to the CSI process and / or a subframe that includes a CSI- channel state interference measurement feature IM corresponding to the CSI process, or in a time domain, the CSI reference resource is a subframe that includes a ZP CSI-RS zero power channel information reference signal resource configured for the user equipment .
[114] The CSI reference resource indication information sent by the first network device is RRC radio resource control signaling.
[115] In the aforementioned modality, CSI processes are CSI processes for periodic reporting or CSI processes for aperiodic reporting.
[116] An embodiment of the present invention additionally provides the following technical solution, which includes the following steps:
obtain, through a user device, at least two CSI processes, in which the at least two CSI processes correspond to a CSI reference resource, and in a time domain, the CSI reference resource is any one or a combination of a subframe that includes a NZP CSI-RS resource, a subframe that includes a CSI-IM resource, or a subframe that includes a ZP CSI45 / 70 resource
LOL; and to process, through the user equipment, the CSI processes according to the CSI reference resource.
[117] Specifically, in the aforementioned modality, if the reference resource includes an NZP CSI-RS resource or a CSI-IM resource in the time domain, the NZP CSI-RS resource or the CSI-IM resource has a minimum period or a minimum subframe shift between NZP CSI-RS resources and CSI-IM resources respectively corresponding to at least two CSI processes;
if the CSI reference resource includes an NZP CSI-RS resource in the time domain, the NZP CSI-RS resource has a minimum period or a minimum subframe offset among NZP CSI-RS resources corresponding to at least two CSI processes;
If the CSI reference resource includes an NZP CSI-IM resource in the time domain, the NZP CSI-IM resource has a minimum period or a minimum subframe offset between NZP CSI-IM resources corresponding to at least two CSI processes; or if the reference resource includes a ZP CSI-RS resource in the time domain, the ZP CSI-RS resource has a minimum period or a minimum subframe offset among ZP CSI-RS resources configured for the user equipment.
[118] In the aforementioned modality, the CSI reference resource is predefined. Alternatively, the method additionally includes:
receive, through user equipment, information
46/70 CSI reference resource indication sent by a first network device, where CSI reference resource indication information is used to indicate that, in a time domain, the CSI reference resource is either or a combination of a subframe that includes a NZP CSI-RS resource, a subframe that includes a CSI-IM resource, or a subframe that includes a ZP CSI-RS resource.
[119] The CSI reference resource indication flag is RRC flag.
[120] In the aforementioned modality, CSI processes are CSI processes for periodic reporting or CSI processes for aperiodic reporting.
[121] An embodiment of the present invention additionally provides a technical solution. That is, a user device obtains a CSI process, in which the CSI process corresponds to at least two CSI reference resources. Specifically, in at least two CSI reference resources, at least one CSI reference resource is a reference resource of a CQI channel part in the CSI process, and is a subframe that includes an NZP CSI-RS resource corresponding to the CSI process in a time domain; and at least one CSI reference feature is a reference feature of a CQI interference part in the CSI process, and is a subframe that includes a CSI-IM feature corresponding to the CSI process in a time domain. In this modality, CSI processes are CSI processes for periodic reporting or CSI processes for aperiodic reporting.
[122] One embodiment of the present invention provides
47/70 additionally the following technical solution. A user device obtains a CSI process, in which a CSI reference resource corresponding to the CSI process consists of multiple subframes in a time domain. The multiple subframes are subframes L before a subframe triggers the CSI process, or include the subframe that triggers the CSI and L-1 subframe process before the subframe triggers the CSI process, where L is a positive integer. In addition, the value of L is predefined, or is notified by a network device. In this modality, CSI processes are CSI processes for periodic reporting or CSI processes for aperiodic reporting.
[123] The aforementioned various embodiments of the present invention can be added according to the following solutions.
[124] The first solution includes the following steps.
[125] For a situation where a CSI process has a CSI reference resource, the user equipment processes the CSI process according to the reference resource.
[12 6] In a time domain, the CSI reference feature is a subframe that includes a non-zero power channel state reference signal feature (Power Channel State Reference feature No Null, NZP CSI-RS resource associated with the CSI process, and / or, in a time domain, the CSI reference resource is a subframe that includes an interference measurement feature (interference measurement feature, IMR) associated with the CSI process.
[127] The second solution is for a situation where a
48/70 CSI process has a CSI reference feature, and the user equipment processes the CSI process according to the reference feature.
[12 8] In a time domain, the CSI reference feature is a subframe that includes a zero power channel state reference signal feature (Zero Power Channel State Reference feature, ZP CSI-RS feature) configured for the user equipment.
[129] The third solution is for a situation where multiple CSI processes have the same CSI reference resource, and the CSI reference resource includes a CSI-RS and / or IMR resource.
[130] User equipment can be notified regarding the configuration of the CSI reference feature in an implicit notification mode. For the first method and the second method: if a NZP CSI-RS resource period associated with the CSI process is longer than an IMR period associated with the CSI process, in the time domain, the CSI reference resource will be a subframe which includes the IMR associated with the CSI process, otherwise, in the time domain, the CSI reference resource will be a subframe that includes the NZP CSI-RS associated with the CSI process; and if an NZP CSI-RS period associated with the CSI process is equal to an IMR period associated with the CSI process, in the time domain, the CSI reference resource will be a subframe that includes the NZP CSI-RS or the IMR associated with the CSI process.
[131] For the third method: if periods of the IMRs corresponding to the multiple CSI processes are
49/70 different, in the time domain, the reference resource will be a subframe that includes the IMR with a minimum period between the IMRs; and if the periods of the IMRs corresponding to the multiple CSI processes are the same, in the time domain, the reference resource will be a subframe that includes the IMR with a minimum subframe offset between the IMRs.
[132] User equipment can also be notified of the configuration of the reference resource in an explicit signaling mode, where the explicit signaling includes RRC (Radio Resource Control, radio resource control) signaling.
[133] The configuration of the reference resource can also be predefined, which includes: it is defined that, in the time domain, the reference resource is a subframe that includes the NZP CSI-RS resource or the IMR corresponding to the CSI process, or it is defined that, in the time domain, the reference resource is a subframe that includes the ZP CSI-RS resource configured for the UE.
[134] The fourth solution is for a situation where a CSI process has two CSI reference resources, where the first CSI reference resource is a reference resource for a CQI channel part in CSI processes, and in the time domain, it is a subframe that includes the CSI-RS resources associated with the CSI process, and the second CSI reference resource is a reference resource of a CQI interference part in the CSI processes, and in the time domain , is a subframe that includes the IMR associated with the CSI process.
[135] The fifth solution is for a situation where a
50/70 CSI reference feature of a CSI process consists of multiple subframes in the time domain. The multiple subframes are subframes L before a subframe triggers the CSI process, or include the subframe that triggers the CSI and L-1 subframe process before the subframe triggers the CSI process.
[136] In the aforementioned modalities of the present invention, when defining that in a time domain, a reference resource corresponding to a CSI process is a subframe or multiple subframes that include a resource (such as NZP CSI-RS and CSI-IM ) that appears in a certain period, a UE only measures and calculates corresponding CSIs according to the reference resource corresponding to the CSI process, and for multiple CSI processes that are triggered many times and have the same reference resource, the UE only needs to measure and calculate the corresponding CSI once, through which the complexity of the UE is canceled for the processing of CSI that is processed, which, in this way, solves a problem of high complexity of UE for processing CSI which is processed, and solves the existing problem after a CoMP technology is introduced in a way that the UE cannot implement the processing of multiple CSI processes. The technical solutions of the present invention can be used in a situation where the user equipment receives a CSI request on a carrier, and can also be used in a situation where the user equipment receives CSI requests on multiple carriers. In the aforementioned modalities of the present invention, the establishment of a first threshold and the establishment of
51/70 of numerical values of N, K and L in a user equipment's CSI process processing capability can be defined for the situation where the CSI request occurs on a carrier; and can also be defined for the situation where CSI requests occur on multiple carriers. Then, the defined numerical values are allocated in the CSI request on each carrier. A numeric value can additionally be set separately for a CSI request on a carrier. In case of CSI requests on C carriers, it is established that corresponding values of CSI requests on C carriers are C times the numerical values defined above. Alternatively, a numerical value can be additionally set separately for a CSI request on a carrier. If there are CSI requests on multiple carriers, it is established that corresponding values of CSI requests on multiple carriers are D times the numerical values defined above, where D is a fixed value, for example, D = 2.
[137] Figure 6 is a first schematic structural diagram of a user equipment according to an embodiment of the present invention. As shown in Figure 6, the user equipment includes a first receiver module 11 and a first measurement processing module 12. The first receiver module 11 is configured to receive a first request for CSI channel status information sent by a first device. network, where the first CSI request is used to trigger aperiodic CSI reporting. The first
52/70 measurement processing 12 is configured for: when CSI corresponding to multiple aperiodic CSI processes has not been reported by the user equipment, CSI corresponding to a portion of aperiodic CSI processes among the multiple aperiodic CSI processes is canceled, where each CSI process is associated with a channel measurement feature and an interference measurement feature.
[138] In the aforementioned embodiment of the present invention, aperiodic CSI processes are CSI processes for reporting aperiodic CSI.
[139] Additionally, where the first measurement processing module cancels CSI corresponding to part of aperiodic CSI processes among multiple aperiodic CSI processes, cancels reporting of CSI corresponding to aperiodic CSI process part among multiple processes of aperiodic CSI.
[140] The multiple aperiodic CSI processes are aperiodic CSI processes corresponding to the first CSI request.
[141] Before receiving the first CSI request sent by the first network device, the first receiver module 11 additionally receives a second CSI request, in which the multiple aperiodic CSI processes are aperiodic CSI processes corresponding to the first CSI request and aperiodic CSI processes corresponding to the second CSI request.
[142] That the first measurement processing module 12 cancels the CSIs that correspond to a part of processes
53/70 aperiodic CSI between multiple aperiodic CSI processes includes: if the number of multiple aperiodic CSI processes exceeds a first threshold, cancel the CSI that corresponds to the aperiodic CSI process share between the multiple aperiodic CSI processes.
[143] In addition, canceled CSIs that correspond to a portion of aperiodic CSI processes among the multiple aperiodic CSI processes include: canceling CSIs that correspond to the aperiodic CSI process portion, so that the number of aperiodic CSI processes not canceled between the multiple aperiodic CSI processes is less than or equal to the first threshold.
[144] The first threshold is predefined, or is notified by the first network device, or is notified by a second network device.
[145] The first measurement processing module 12 is specifically configured to cancel, according to a priority or cancellation rule, the CSIs that correspond to the part of aperiodic CSI processes among the multiple aperiodic CSI processes that correspond to the first request of CSI; or cancel the CSI that correspond to all aperiodic CSI processes that correspond to the first CSI request, where the CSI that correspond to all aperiodic CSI processes that correspond to the first CSI request are the CSI that correspond to the process part of aperiodic CSI.
[146] In addition, the first measurement processing module 12 is specifically configured to cancel, according to a cancellation priority or rule,
