    Field of Invention
    The present invention relates to the field of mobile communication technologies, and in particular, to a method, a device and a system for configuring a component carrier in an aggregation situation. Fundamentals of the Invention
    LTE (Long Term Evolution) is an evolved network of a universal mobile communication system. One purpose of LTE is to provide a low-cost network capable of reducing delay, raising a user data rate, and increasing system capacity and coverage. In
    LTE-A (Advanced Long Term Evolution), a new feature of . network is introduced on the basis of LTE, such as CA (Carrier Aggregation), that is, each CA cell has multiple CCs (Component Carriers) and each CC can be considered a single LTE carrier cell, so that a CA cell of LTE-A has higher bandwidth and higher throughput.
    In an LTE/LTE-A system, before data is transmitted between a base station and a UE (User Equipment), the base station must first configure a transmission resource used by the UE, where the transmission resource is then furthermore, referred to as a resource, and may include a frequency channel and a time and frequency resource.
    In the LTE system, according to a service characteristic and through a PDCCH (Physical Downlink Control Channel) command and an RRC (Radio Resource Control Connection Reconfiguration) message, the base station configures a used resource by the UE, 30 which may include configuration parameters such as physical resource information, MCS (Modulation and Coding Scheme) modulation and coding information, and a resource scheduling period.
    A multi-carrier technology is introduced in the LTE-A system, which is obviously advantageous over a single-carrier approach in terms of performance such as spectrum efficiency and amount of transmission information. However, in a multi-carrier situation, how the base station configures each parameter of the resource is not specified. The prior art has the following disadvantages: if a conventional method for setting a resource in an LTE system is still used to set a related parameter, the UE cannot know precisely to which component carrier the resource parameter 10 is applied, so that data may fail to be transmitted or a transmission error may occur.

    The technical solutions of the present invention are described below with reference to the accompanying drawings and embodiments.
    Figure 1 is a flowchart of a method for configuring a component carrier in a carrier aggregation situation in accordance with an embodiment of the present invention. The method can include:
    Step 101: Obtaining information about a component carrier supported by a UE. When starting a service in LTE-A, the UE can report information about the component carrier supported by the UE to a base station, and the support information can also be searched and retrieved by the base station from the UE, and a core network can also notify the base station about the capacity that is reported by the UE at the time of connection, and the support information can also be reported by the UE to the station base at the time of establishing an RRC connection, or may be reported to the base station via an uplink information transfer message (UL Information Transfer) at the time of service start. The information may include a supported component carrier and the number of supported component carriers, a supported Band List EUTRA (Supported EUTRA band list (Enhanced Universal Terrestrial Radio Access)), and Meas Parameters (Measurement Parameters).
    Step 102: Selecting a candidate component carrier according to information about the component carrier and setting a resource parameter that is applied to the candidate component carrier to form configuration information about the candidate component carrier.
    After the base station obtains the support information, when a relevant parameter of a resource needs to be configured for the UE, the base station can select a candidate component carrier according to factors such as the candidate component carrier supported by the UE and a loading each component carrier into a cell, and setting the resource parameters that are applied to the candidate component carrier, such as a period, a PUCCH (Physical Uplink Control Channel) resource, the number of HARQ (Request) processes Automatic Repeating System) for semi-static programming, and a condition for the implicit release of a semi-static programming feature. For details on how to select the candidate component carrier, reference can be made to the description of the subsequent modalities.Step 103: The distribution of configuration information about the candidate component carrier to the UE.
    The base station distributes configuration information about the candidate component carrier, i.e. information about a selected component carrier to the UE and information about a configured parameter, to the UE, so that when necessary, by applying a relevant parameter of a setting resource for a corresponding component carrier, the UE may activate, notify and release a resource to complete resource scheduling and transfer on each component carrier.
    In this embodiment of the present invention, the base station can select, according to the obtained component carrier support information, the candidate component carrier for the UE, and perform the resource configuration, so that after receiving the configuration information about the component carrier, the UE can know precisely to which component carrier a resource parameter is applied, and thus data transmission can be performed and a data transmission error can be reduced. A specific implementation process of the method in the present invention is described below with reference to a specific embodiment.
    Figure 2 is a flowchart of a method for configuring a component carrier in another carrier aggregation situation in accordance with an embodiment of the present invention. The method can include:
    Step 201: A UE monitors broadcast system information to obtain component carrier support information about a cell to which the UE belongs.
    The cell broadcasts the component carrier support information about the cell through the system information, and the UE can obtain the total number of component carriers of the cell and relevant situation information through monitoring and measurement. Monitoring can be continuous real-time monitoring, it can also be timed periodic monitoring, and it can also be event-driven monitoring, that is, monitoring is based on a requirement, which can be determined according to a specific requirement .Step 202: The UE reports information about a supported component carrier to a base station.
    The support information includes the supported component carrier and the number of supported component carriers, and an EUTRA of Supported Band List and Meas Parameters. The UE can report the information to the base station by forming the information in a data table.
    In this mode, the base station obtains, through steps 201 to 202, information about a component carrier supported by the UE. Definitely, the information can also be obtained by other means.
    Step 203: The base station obtains a load of each component carrier supported by the UE, and determines a component carrier whose load is less than a threshold as a candidate component carrier.
    A process in which the base station selects the candidate component carrier may be first listing each component carrier reported by the UE, then invoking and loading a load situation of each component carrier to the list, and then performing the selection from the list accordingly. with the load situation. The base station maintains application status information about all component carriers under the base station, and can search and find, according to information such as the name of a component carrier, whether the component carrier has been allocated to another terminal, and /or according to the number of terminals that are allocated on the component carrier, and a current application situation of the component carrier, a load value of each component carrier is obtained by calculating a parameter to measure an application situation of each component carrier according to a certain proportional relationship. The larger the payload value, the smaller the allocation capacity of a component carrier. The proportional relationship can be determined according to a base station configuration requirement. A load ranking order of each component carrier reported by the UE is obtained by comparing the load values of each component carrier, and a component carrier whose load value is less than a threshold is served as a candidate component carrier that is allocated by the base station to the UE. The threshold can be a predetermined fixed value and can also be a dynamic value, for example candidate component carriers are component carriers corresponding to the first three or first several load values in a list where the load values are sorted in ascending order.
    In this step, according to factors such as each component carrier reported by the UE and a load of each component carrier of the base station itself, the base station may configure for the UE a set of candidate component carriers and a resource parameter shared by the set, and can also configure for the UE one or multiple candidate component carriers and a resource parameter that is applied to a corresponding component carrier, i.e., a resource parameter is corresponding to a component carrier one to one. For example: a 1 component carrier, a T1 semi-static scheduling period, a PUCCH resource S1, the number of HARQ processes N1, and an implicit release condition H1; a 2 component carrier, a T2 semi-static scheduling period , a PUCCH resource S2, the number of HARQ processes N2, and a condition for implicit release H2;
    Step 204: The base station distributes the configuration information about the candidate component carrier to the UE.
    The base station can form the configuration information about the candidate component carrier, i.e., the information about the candidate component carrier and the information about a resource parameter configured for the candidate component carrier, in a data table and sends the table of data to the UE via an RRC message.
    In this mode, after the UE obtains, by monitoring a system broadcast, information about the component carrier supported by the UE, and reports the information to the base station, the base station selects and configures the candidate component carrier so that after receiving the configuration information about the component carrier, the UE can know precisely to which component carrier a resource parameter is applied, and therefore data transmission can be performed and a data transmission error can be reduced .
    Figure 3 is a flowchart of a method of configuring a component carrier in another carrier aggregation situation in accordance with an embodiment of the present invention. The method can include:
    Step 301: After entering a connected state, a UE receives component carrier support information which is notified through dedicated signaling by a cell to which the UE belongs.
    In this step, the UE can obtain the component carrier support information by receiving a dedicated signaling notification. The receipt of the notification can be a continuous real-time reception, but it can also be a timed periodic reception, and it can also be an event-triggered reception, that is, the reception is based on a requirement, which can be configured according to a specific requirement. The UE obtains the component carrier support information by receiving the dedicated signaling notification so that the support information is more accurate. Step 302: The UE reports information about a supported component carrier to a base station.
    In addition to the supported component carrier and the number of supported component carriers, and a supported Band List EUTRA and Meas Parameters, the support information may additionally include a channel condition of each component carrier received by the UE, e.g. RSRP (Reference Signal Received Power) and RSRQ (Reference Signal Received Quality) that can be used when the base station configures a component carrier and a resource parameter for the UE.
    The UE report to the base station can be a real-time report, or a timed report, or an event-driven report to the base station, so that new configuration information is obtained in time, and thus the accuracy of data transmission is improved.
    In this mode, the base station obtains, through steps 301 and 302, information about a component carrier supported by the UE. Definitely, the information can also be obtained by other means.
    Step 303: The base station obtains a load of each component carrier supported by the UE, and determines a component carrier whose load is less than a threshold and channel quality is greater than a threshold as a candidate component carrier.
    In this step, a process in which the base station selects the candidate component carrier is similar to the corresponding step 203 in the above modality, and it can also be first listing each component carrier reported by the UE, then invoking and loading a load situation of each component carrier and a channel quality situation of each component carrier to the list, and then performing the selection from the list according to the load situation and the channel quality situation.
    The base station obtains a load value of each component carrier by using a method similar to the above modality, and meanwhile can obtain a channel quality reference value of a corresponding component carrier according to a relevant parameter of channel quality of each component carrier and a certain proportional relationship. A process in which the base station selects a candidate carrier may be selecting one or multiple component carriers whose load value is less than a threshold value and a channel quality reference value is greater than a threshold value. from the list as a candidate component carrier, where the list includes load values and channel quality benchmarks. The specific number of selected component carriers and a parameter threshold value, and a threshold are determined by the base station.
    In another embodiment of the present invention, the base station may also select and determine a candidate component carrier according to only the channel quality of a component carrier, and choose a component carrier with better channel quality as a candidate component carrier or choose the first several component carriers with better channel quality as candidate component carriers.
    In this step, the base station may configure for the UE one or multiple candidate component carriers and a resource parameter that is applied to a corresponding component carrier, and may also configure a set of candidate component carriers for the UE. The set is a subset of a set of all component carriers of the cell to which the UE belongs. Meanwhile, the base station configures a set of parameters of a resource required by the UE, and the parameters can be applied to each component carrier in the component carrier set. For example: a set of component carriers: a component 1 carrier, a component 2 carrier, ...; and parameters applied to the set of component carriers: a semi-static scheduling period T1, a PUCCH resource S, the number of processes HARQ N, and a condition for implicit release H.
    Step 304: The base station distributes configuration information about the candidate component carrier to the UE.
    The configuration information about the candidate component carrier, that is, the information about the candidate component carrier and a resource parameter configured for the candidate component carrier, can be sent to the UE via an RRC message.
    In this mode, after the UE obtains, upon receipt of a dedicated signaling notification, information about the component carrier supported by the UE, and reports the information to the base station, the base station selects and configures the candidate component carrier, so that after receiving the configuration information about the component carrier, the UE can know precisely to which component carrier the resource parameter is applied, and therefore data transmission can be performed and a data transmission error can be reduced.
    Additionally, when a relevant parameter is configured by applying a conventional method for configuring a resource in an LTE system, when a component carrier used by the UE changes, a resource parameter needs to be reconfigured through an RRC message, causing an signaling waste and a delay problem. In this embodiment of the present invention, the base station can configure for the UE, at a time, a set of component ras-carriers and a parameter that can be applied to multiple component carriers, so that when a particular component carrier used by the UE changes , a set of candidate component carriers allocated by the base station can be fetched, and since the resource parameters of the component carriers in the set are the same, the UE can be directly transferred to another configured component carrier in the set, so that a parameter of feature is not reconfigured, thus saving signaling overhead and reducing delay. Meanwhile, the configuration consistency of the component carriers between the UE and the base station can be maintained, and a correct operation of the UE can be maintained.
    The method of each modality above can not only be applied to the first component carrier configuration that is performed by the base station in the UE, but also be applied to operations, such as adding, modifying and deleting, performed by the base station in the carrier configuration component of the UE, which is described below through a specific modality.
    Figure 4 is a flowchart of a method for configuring a component carrier in another carrier aggregation situation in accordance with an embodiment of the present invention. The method can include:
    Step 401: A UE reports status change information about a supported component carrier to a base station.
    When the channel quality of a candidate component carrier allocated by the base station to the UE changes, or the channel quality of a component carrier supported by a UE changes, or a new component carrier that is supported by the UE appears, the UE may report the change information about the supported component carrier for the base station. The reported change information may include a name of a component carrier and the number of component carriers that change, and may additionally include changed status information, for example, an original level and a final level of channel quality of a component carrier. determined.
    In a process where a service is continuously running, the UE can report change information about a component carrier in real time, in a timed manner by setting a timer, or in an event-triggered manner based on a requirement. The UE can also set a limit on the channel quality of the component carrier. When the channel quality of a component carrier applied by the UE side changes and reaches a certain threshold, or the channel quality of a component carrier being used is less than a certain threshold, the UE can be triggered to report the change information, so that the UE performs a temporal report, and thus the base station reconfigures a candidate component carrier and a resource parameter for the UE according to the reported change information when necessary.
    Step 402: The base station obtains a load of each component carrier supported by the UE, and determines a component carrier whose load is less than a threshold and the channel quality is greater than a threshold as a candidate component carrier.
    The base station performs an analysis according to a change situation of a component carrier on the UE side or channel quality of the component carrier on the UE side and, if necessary, modifies the component carrier used by the UE or the set of component carriers used by the UE, for example, adds or deletes a component carrier, or modifies some parameters. For example, for the change information on the component carrier, where the change information is reported by the UE, the base station can eliminate, according to a load limit and a channel quality reference value, a component carrier that is originally allocated to the UE, but whose channel quality becomes less than a threshold, and relocates a new component carrier that matches the two previous conditions to the UE.Step 403: The distribution of configuration information about the carrier candidate component for the EU.
    The base station notifies the UE of the configuration information about the candidate component carrier, that is, the information about a modified candidate component carrier and information about a modified resource parameter, through an RRC message.
    After the UE receives the candidate component carrier and resource parameter that are configured by the base station, if a resource is in an active state on a component carrier, and the UE receives a resource activation command, but the command indicates that the resource is on another component carrier, the UE uses a new resource activation command to apply a new resource to a reconfigured component carrier, and in the meantime releases a resource on an original component carrier.
    In this mode, the UE reports a supported component carrier change situation so that the base station adjusts or modifies the component carrier configuration of the UE in time, and therefore the UE can perform data transmission on a component carrier newly configured more efficiently.
    Those skilled in the art can understand that all or part of the steps in the methods of the above embodiments can be implemented by a program instructing the relevant hardware. The program can be stored on a computer-readable storage medium, and when the program is executed, including the following steps: obtaining information about a component carrier supported by a UE; selecting a candidate component carrier according to the information about the component carrier and configuring a resource parameter that is applied to the candidate component carrier to form configuration information about the candidate component carrier; and distributing configuration information about the candidate component carrier to the UE. The storage medium may be a ROM/RAM, a magnetic disk, and an optical disk.
    The method of configuring a component carrier in a carrier aggregation situation is described in detail above and a structure of a corresponding apparatus is described in the embodiments below.
    Figure 5 is a schematic structural diagram of a base station in accordance with an embodiment of the present invention.
    The base station may include: a obtainment module 501, adapted to obtain information on a component carrier supported by a UE; a selection module 502, adapted to select a candidate component carrier in accordance with information on the component carrier; configuration 503, adapted to configure a resource parameter that is applied to the candidate component carrier to form configuration information about the candidate component carrier; and a distribution module 504, adapted to distribute configuration information about the candidate component carrier to the UE.
    At the base station, after the obtaining module 501 obtains the information about the component carrier supported by the UE, the selection module 502 can select the candidate component carrier for the UE according to factors such as the number of component carriers supported by the UE and a payload of each component carrier of a cell, and the configuration module 503 configures a parameter relevant to a resource for the UE to form configuration information about a candidate component carrier, and finally, the distribution module 504 distributes information information about the candidate component carrier, that is, information about the candidate component carrier and information about a configured parameter, for the UE.
    In this mode, through each module, the base station perceives and analyzes a support situation of a component carrier on one side of the UE, and configures the component carrier of the UE, so that the configuration of the component carrier is kept consistent across the UE and the base station, and correct data transmission is guaranteed.
    Figure 6 is a schematic structural diagram of another base station in accordance with an embodiment of the present invention.
    The base station may also include an acquisition module 601, a selection module 602, a configuration module 603 and a distribution module 604 and except for the selection module 602, all modules are similar to the corresponding modules in the previous modality and not are described repeatedly here.
    In this embodiment, the selection module 602 may additionally include a charge acquisition unit 6021 and a determination unit 6022.
    The payload acquisition unit 6021 is adapted to obtain a payload of each component carrier supported by a UE.
    The determination unit 6022 is adapted to determine a component carrier whose charge is less than a threshold as a candidate component carrier.
    In the selection module 602, the load acquisition unit 6021 obtains a load situation of each component carrier, and the determination unit 6022 can measure each component carrier according to the load situation and determine a component carrier whose load is less than a threshold as a candidate component carrier to be allocated to the UE, so that the configuration of the component carrier is optimized.
    In another embodiment of the present invention, if the component carrier information supported by the UE, where the component carrier information is obtained by the obtaining module 601, further includes information on the channel quality of each component carrier, the determination unit 6022 included in selection module 602 is adapted to determine a component carrier whose load is less than a threshold and a channel quality that is greater than a threshold as the candidate component carrier. The candidate component carrier determined by the base station through the determination unit is more reliable so that data transmission is guaranteed.
    The base station obtainment module 601 can further obtain status change information about a component carrier on a UE side, such as reducing or increasing the number of component carriers, and channel quality of each component carrier, and, accordingly, an analysis performed by the base station according to a change situation of the component carrier on the UE side or channel quality of the component carrier on the UE side, the selection module 602 and the configuration module 603 being able to modify a carrier component used by the UE or a set of component carriers used by the UE, for example, adding or deleting a component carrier, or modifying some parameters, and then the distribution module 604 notifies the UE via an RRC message.
    Figure 7 is a schematic structural diagram of a mobile terminal in accordance with an embodiment of the present invention.
    In this embodiment, a mobile terminal may include a reporting module 701 and a configuration receiving module 702.
    Reporting module 701 is adapted to report support information on a component carrier to a base station. The configuration receiving module 702 is adapted to receive configuration information about a candidate component carrier, that is, information about the candidate component carrier and information about a resource parameter that is applied to the candidate component carrier, where the information about the carrier candidate component is distributed by the base station.
    The mobile terminal can report, via the reporting module 701, the component carriers that the mobile terminal can simultaneously support and the number of component carriers, and can also simultaneously report a channel condition of each component carrier, such as RSRP, and then , after the base station performs an analysis and judgment according to the reported information, the base station selects a candidate component carrier for the mobile terminal and sets a resource parameter. The mobile terminal receives configuration from the base station via the configuration receiving module 702, and thereafter can apply a relevant parameter of a resource configuration to a corresponding component carrier, such as activation, modification, and resource release, so to complete resource and transfer scheduling on each component carrier.
    In this embodiment of the present invention, the reporting module 701 reports support information about the component carrier, so that the base station can configure the component carrier of the mobile terminal according to the support information and therefore after the module After receiving configuration 702 from the mobile terminal receives configuration information about the component carrier, the mobile terminal can know precisely to which component carrier a resource parameter is applied. In this way, data transmission can be performed or a data transmission error can be reduced.
    Figure 8 is a schematic structural diagram of another mobile terminal in accordance with an embodiment of the present invention.
    In this mode, the mobile terminal may additionally include a monitoring module 803 in addition to a reporting module 801 and a configuration receiving module 802.

    Monitoring module 803 is adapted to monitor broadcast system information to obtain a list of component carrier support information of a cell.
    By monitoring and measuring the broadcast system information about the cell through the monitoring module 803, the mobile terminal can obtain the total number of component carriers of the cell and information about a relevant situation, such as a channel condition of each component carrier. . Monitoring can be real-time monitoring, timed monitoring, or event-triggered monitoring, which can be determined according to a requirement. Taking timed monitoring as an example, a timer can be assigned to perform timed monitoring. Then, the reporting module 801 reports to the base station the support information about a component carrier, where the support information about the component carrier is obtained by monitoring, and the configuration receiving module 802 receives configuration information about a carrier base station component. The configuration information may include at least one component carrier and a parameter for configuring a resource, where the parameter for configuring a resource is applied to a corresponding component carrier, and may also include a set of component carriers and a parameter for configuring a resource , where the parameter to configure a resource is applicable to all component carriers in the set. After receiving the configuration from the base station, the mobile terminal can apply a relevant parameter to configure a resource for a corresponding component carrier, such as activation, modification and release of the resource, in order to complete the programming of the resource and transfer each component carrier .
    In this embodiment, the monitoring module 803 monitors the broadcast system information about the cell to obtain the list of component carrier support information so that the accuracy of the component carrier support information reported to the base station is improved, and the component carrier support information can also be reported to the base station in accordance with a changing situation of the cell component carrier, so that new configuration information can be obtained in time, thus improving transmission accuracy. of data.

The receiving module is adapted to receive component carrier support information notified by a cell after the mobile terminal enters a connected state.
    This modality is different from the previous modality in that in the previous modality the mobile terminal monitors the information of the broadcasting system about the cell through the monitoring module 803 to obtain the list of component carrier support information, while in this modality the mobile terminal receives a dedicated signaling notification from a cell via the receiving module to obtain component carrier support information. In this embodiment, a list of component carrier support information can also be obtained through the receiving module, so that the accuracy of component carrier support information reported to a base station is improved, and a report can also be made for the base station according to a changing situation of a component carrier of the cell, so that new configuration information can be obtained in time, thus improving the accuracy of the data transmission.
