field of invention
The present invention relates to the field of communication, and in particular to a method and a device for transmitting data. State of the Art
The Long Term Evolution system physical uplink channels (LTE for short) comprise a physical random access channel (PRACH for short), a physical uplink shared channel (PUSCH for short), and a control channel. physical uplink 10 (PUCCH for abbreviation). Additionally, there are two types of physical uplink signals, one type is demodulation reference signal (DMRS for abbreviation) for demodulating a control/data signal, and the other type is probe reference signal (SRS for abbreviation) for measure an uplink channel. PUSCH/PUCCH has two different types of 15 lengths of cyclic prefix (CP for abbreviation), ie normal cyclic prefix (Normal CP for abbreviation) and extended cyclic prefix (Extended CP for abbreviation).
In the current LTE system, a physical uplink control information (Uplink Control Information, UCI for abbreviation) comprises an ACK/NACK, a channel status information (CSI, where the CSI includes: an Indicator of Channel Quality (CQI), a Precoding Matrix Indicator (PMI) and Position Indicator (RI)), and a scheduling requirement (SR) and a combination when they are simultaneously transmitted. It is also prescribed by LTE that if there is no PUSCH transmission in the current subframe, one or more types of the above UCIs (only limited to combinations of two types of UCIs) are transmitted in the PUCCH, and if there is PUSCH transmission in the current subframe , one or more types of the above UCIs are transmitted in the PUSCH along with the data.
LTE defines multiple types of PUCCH format, including PUCCH format 1/1a/1b (a schematic diagram of channel structure thereof is as shown in Fig. 1) and format 2/2a/2b (a schematic diagram of channel structure of the same is as shown in Fig. 2), wherein format 1 is configured to transmit a scheduling request from a UE, format 1a 35 and format 1b are configured to feed back a 1-bit ACK/NACK and 2-bit ACK/NACK respectively, format 2 is configured to transmit downlink channel status information, format 2a is configured to transmit CSI information multiplexed with 1-bit ACK/NACK, and format 2b is configured to transmit CSI information multiplexed with 2-bit ACK/NACK.
Additionally, in order to support simultaneous transmission of the PUCCH 1/1 a/1 b format and an SRS, LTE also defines the shortened format of the PUCCH 1/1 a/1 b format, that is, the PUCCH is not configured to transmit the PUCCH on the last symbol of a subframe, and the last symbol of the subframe is configured to transmit the SRS. With respect to the shortened format, a format in which a last symbol of a subframe is configured to transmit PUCCH is called a normal PUCCH format.
The SRS is a signal transmitted from the UE to the eNB to wirelessly measure the channel information (channel status information, CSI for abbreviation) by an eNB. In the LTE system, the UE transmits an uplink SRS periodically in the last symbol of a subframe according to parameters such as broadband, frequency domain location, cyclic sequence exchange, subframe offset and period configured by an eNB. The eNB determines an uplink CSI of the UE in accordance with a received SRS and performs operations such as frequency domain selection scheduling and closed loop power control in accordance with the obtained CSI. LTE only supports periodic SRS. Therefore, in the following descriptions, the SRS always refers to the periodic SRS if there is no specific instruction.
It is prescribed by LTE that the SRS is transmitted in the last symbol of a subframe and meanwhile, in order to maintain single carrier properties of an uplink signal and to avoid mutual interference between an SRS and a PUSCH/PUCCH of different UEs, LTE makes the following adjustments. (1) When the UE needs to simultaneously transmit PUSCH and SRS in certain subframe, the last symbol of the corresponding subframe does not transmit PUSCH, and the SRS is transmitted in the last symbol of the subframe. (2) When the UE only needs to transmit the PUSCH in certain subframe, if the subframe is configured by upper layer as a cell-specific SRS subframe, then when a resource allocation of the PUSCH partially overlaps with the wideband configuration of Cell-specific SRS 35 configured by upper layer, the last symbol of the subframe does not transmit the PUSCH; otherwise, the last symbol of the subframe transmits the PUSCH. (3) When the UE needs to transmit PUCCH and SRS simultaneously in certain subframe, if the PUCCH is of the PUCCH 1/1a/1b format, then when an upper layer configured parameter of AN-and-SRS-simultaneous is TRUE, the PUCCH is transmitted using a shortened format, and the SRS is transmitted in the last symbol of the subframe; otherwise, the PUCCH is transmitted using a normal format and meanwhile the SRS is omitted (ie, no SRS is transmitted in the current subframe). (4) When UE needs to transmit PUCCH and SRS simultaneously in certain subframe, if PUCCH is of PUCCH 2/2a/2b format, then UE transmits only PUCCH and meanwhile SRS is omitted.
In an International Mobile Telecommunications (Advanced) (IMT-Advanced for 15 abbreviation) system, a high-speed data transmission can be performed, and there is a very large system capacity. A peak rate of IMT-Advanced system can reach 1 Gbit/s in a low speed motion situation and hotspot coverage, and 100Mbit/s in a high speed motion situation and wide area coverage.
In order to meet the requirements of the International Telecommunication Union-Advanced (ITU-Advanced for abbreviation), the Long Term Advanced Evolution System (LTE-A for abbreviation) system as the LTE evolution standard , should support wider system bandwidths (above 100MHz), and 25 also needs to be backward compatible with existing LTE standards. On the basis of the existing LTE system, the widebands of the LTE system can be combined to get a wider bandwidth, which technology is called carrier aggregation technology (CA for abbreviation). This technology is able to improve the use of frequency spectrums of the IMT-Advanced 30 system, alleviating the lack of frequency spectrum resources and also optimizing the use of frequency spectrum resources.
In a system for which CA is introduced, a transporter performing aggregation is called a Component Carrier 35 (CC, for abbreviation), and is also called a cell. In addition, primary component cell/carrier (PCC/PCell, for abbreviation) and secondary component cell/carrier (SCC/SCell, for abbreviation) concepts are also introduced. A system having performed the CA at least comprises a primary component carrier and a secondary component carrier, wherein the primary component carrier is always in an activated state. In the following descriptions, the component carrier and cell are equivalent.
After the introduction of the CA, in the current discussion about relationships between a downlink component carrier, a PDSCH transmission block, and a HARQ process, a basic working assumption is that when no space division multiplexing is used, a carrier of downlink component is corresponding to a PDSCH transmission block and a HARQ process, that is to say, the UE needs to feed back a 1-bit ACK/NACK for a PDSCH transmission block of each component carrier. When space division multiplexing is used, it is currently prescribed by LTE-A that a maximum of two transmission blocks are supported. As a result, when space division multiplexing is used, the UE needs to feed back a 2-bit ACK/NACK for two PDSCH transmission blocks from each downlink component carrier.
In an LTE-A system where frequency spectrum aggregation technology is used, the uplink broadband and the downlink broadband may comprise a plurality of component carriers. When an eNB has PDSCHs in a plurality of downlink component carriers to be programmed for a certain UE, and when the UE has no PUSCHs to be transmitted in a current subframe, a terminal should feed back the ACK/NACK for the PDSCHs of the plurality of downlink component carriers in the PUCCH. A current working assumption is that these ACKs/NACKs are transmitted on a UE-specific uplink component carrier; as for SR information, a current working assumption is that the UE transmits only one SR, and the SR information is transmitted on a UE-specific uplink component carrier; and as for CSI information, a current working assumption is that the CSI information is transmitted on a specific UE uplink component carrier.
In the LTE-A system, a current working assumption is that the UE transmits the SR information using the PUCCH 1 format, and the UE transmits the CSI using the PUCCH 2 format. As for the ACK/NACK, it may not be transmitted only by PUCCH 1a, 1b and channel selective multiplexing format, which 5 has been defined in LTE, but also by a new format based on DFT-s-OFDM, which is added to LTE-A to transmit ACK/NACK with one payload useful larger, and the schematic diagram of channel structure of the DFT-s-OFDM based format is as shown in Fig. 3. For the sake of convenient description, this format is called PUCCH 3 Format. can support a 4-bit ACK/NACK feedback, the ACK/NACK itself will be fed back in a PUCCH 1b format way with channel selection, and for a next generation UE that can support more than ACK/NACK feedback 4 bits, the mode in which the UE feeds back the ACK/NACK is configured by the upper layer signaling .
In addition to AC technology, a multi-uplink antenna is also introduced in LTE-A, and a maximum of four antennas can be configured as uplink transmit antennas. Therefore, in order to obtain the channel status information of each uplink transmit antenna, the UE needs to transmit the SRS on multiple antennas simultaneously.
It is presented in the existing LTE-A survey that in uplink communication, non-precoded (i.e., antenna-specific) SRS should be used, and the DMRS of the PUSCH should be precoded. The eNB can have an estimate of an original uplink CSI when receiving the non-precoded SRS, and the DMRS that has been precoded cannot allow the eNB to have an estimate of the original uplink CSI. At that time, when the UE transmits the non-precoded SRS by using multiple antennas, SRS resources needed by each UE are increased, which also results in decreasing the number of UEs that can be simultaneously multiplexed in the system. Nevertheless, in addition to retaining the original periodic transmission of the LTE SRS in order to improve the SRS resource utilization rate and improve the flexibility of resource scheduling, the SRS can also be transmitted aperiodically via control information downlink or upper layer signaling for a UE.
In LTE-A, in order to make full use of the uplink resources and consider the channel quality generally good in a carrier aggregation application scenario, requirements for the single carrier properties of the uplink signal are relaxed, and PUCCH and PUSCH are allowed to be transmitted simultaneously. Whether to allow UE to transmit PUCCH and PUSCH simultaneously or not can be configured with upper layer parameters.
Therefore, in the LTE-A system, when faced with the introduction of various new technologies, such as CA, top link multi antenna, PUCCH 3 format, aperiodic SRS and simultaneous transmission of PUCCH and PUSCH, the existing UE cannot perform simultaneous transmission of a plurality of physical uplink channel/signal types. Summary of the invention
The present invention is proposed by considering the problem that the existing UE cannot perform simultaneous transmission of a plurality of physical uplink channel/signal types when faced with the introduction of various new technologies.

After that, the process of implementing embodiments of the present invention will be described in detail together with examples.
In order to make this convenient for understanding how the principles of the present invention are applied in practice, detailed descriptions will be provided below along with exemplary embodiments.
For ease of descriptions, as shown in Fig. 5, it is assumed that a UE is configured, via higher layer signaling, with a plurality of uplink component carriers UL CC#1, UL CC#2 and UL CC#3, where UL CC#2 is an uplink component carrier (UL PCC), and where subframes #i/#k are subframes that are configured by an upper layer of UL CC#1, specific to cell and configured to transmit the SRS, subframes #i/#k/#l are subframes that are configured by an upper layer of UL CC#2, cell specific and configured to transmit the SRS, and subframes #i/#j/ #1 are subframes that are configured by an upper layer of UL CC#3, and cell-specific and configured to transmit SRS. Additionally, for the sake of simple and convenient illustration, all of the SRSs below comprise periodic SRS and non-recurring SRS if there is no specific instruction. Mod 1
As shown in Fig. 6, it is assumed that in a #i subframe, a UE needs to simultaneously transmit a PUSCH and an SRS in a UL CC#2. Since subframe # can transmit SRS, current subframe #i necessarily is an SRS subframe which is configured by an upper layer of UL CC#2, and cell specific. According to rule 1, the UE transmits no PUSCH in the last symbol of the subframe #i, and then according to rule 8, since no PUSCH is transmitted in the last symbol of the subframe #i, the UE transmits the SRS in the last symbol of subframe #i. Modality 2 Example 2-1
As shown in Fig. 7, it is assumed that in a #i subframe, a UE needs to transmit a PUSCH in an UL CC#2, and transmit an SRS in an UL CC#1. As for UL CC#2, since subframe #i is an SRS subframe that is configured by an upper layer of UL CC#2, it is cell specific, and it is assumed here that a PUSCH resource allocation in UL Current CC#2 and a wideband of an SRS which is configured by an upper layer of the UL CC#2, and cell-specific, have an overlapping part, the UE transmits no PUSCH in the last symbol of subframe #i according to rule 2, and then according to rule 8, since no PUSCH is transmitted in the last symbol of subframe #i, the UE transmits the SRS in UL CC#1 in the last symbol of subframe #i. Example 2-2
As shown in Fig. 8, it is assumed that in a #i subframe, a UE needs to transmit a PUSCH in an UL CC#2, and transmit an SRS in an UL CC#1. As for UL CC#2, since subframe #i is an SRS subframe that is configured by an upper layer of UL CC#2, it is cell specific, and it is assumed here that a PUSCH resource allocation in the Current UL CC#2 and a wideband of an SRS which is configured by an upper layer of the UL CC#2, and cell-specific, have an overlapping part, according to rule 2, the UE transmits the PUSCH in the last symbol of subframe #i, and then according to rule 7, since there is the PUSCH transmitted in the last symbol of subframe #i, the SRS in UL CC#1 is taken out and not transmitted. Example 2-3
As shown in Fig. 9, it is assumed that in a #j subframe, a UE needs to transmit a PUSCH in an UL CC#2, and transmit an SRS in an UL CC#3. As for UL CC#2, since subframe #j is not an SRS subframe which is configured by an upper layer of UL CC#2, and cell specific, according to 1, the UE transmits the PUSCH in the last symbol of subframe #j, and then according to rule 7, since there is the PUSCH transmitted in the last symbol of subframe #j, the SRS in UL CC#3 is taken out and not transmitted. Example 2-4
As shown in Fig. 10, it is assumed that in a #j subframe, a UE needs to transmit a PUSCH in an UL CC#2, and transmit an SRS in an UL CC#3. As for UL CC#2, subframe #j is believed not to be an SRS Subframe that is configured by an upper layer of UL CC#2 and cell specific, subframe #j is an SRS subframe that is configured by a top layer of UL CC#3 and cell specific. Then, according to rule 3, the UE transmits no PUSCH in the last symbol of subframe #j, and then, according to rule 8, since there is no PUSCH transmitted in the last symbol of subframe #j, the UE transmits the SRS at UL CC#3 in the last symbol of subframe #j. Modality 3 Example 3-1
As shown in Fig. 11, it is assumed that in a #i subframe, a UE needs to simultaneously transmit PUCCHs and an SRS in a UL CC#2, the PUCCHs are one of PUCCH 1/1 a/1 b/3 format, and an upper-layer configured parameter of AN-and-SRS-simultaneous is TRUE. According to rule 4, UE transmits the PUCCHs in subframe #i by using a shortened format, that is, no PUCCH is transmitted in the last symbol of subframe #i, and then according to rule 8, since no PUCCH is transmitted in the last symbol of subframe #i, the UE transmits the SRS in the last symbol of subframe #i. Example 3-2
As shown in Fig. 12, it is assumed that in a #i subframe, a UE needs to simultaneously transmit PUCCHs and an SRS in a UL CC#2, the PUCCHs are one of PUCCH 1/1 a/1 b/3 format, and an upper-layer configured parameter of AN-and-SRS-simultaneous is FALSE. According to rule 4, UE transmits the PUCCHs in subframe #i when using a normal format, i.e. there are PUCCHs transmitted in the last symbol of subframe #i, and then according to rule 7, since there are PUCCHs transmitted in the last symbol of subframe #i, UE pulls out and does not transmit the SRS on UL CC#2. Modality 4 Example 4-1
As shown in Fig. 13, it is assumed that in a #i subframe, a UE needs to transmit PUCCHs in an UL CC#2 and transmit an SRS in an UL CC#1, the PUCCHs are one of PUCCH format 1/1 to /1 b/3, and an upper-layer configured parameter of AN-and-SRS-simultaneous is TRUE. Since subframe #i is an SRS subframe which is configured by an upper layer of UL CC#2 and is cell specific, according to rule 4, the UE transmits the PUCCHs in UL CC#2 in subframe # when using a shortened format, ie no PUCCH is transmitted in the last symbol of subframe #i, and then according to rule 8, since no PUCCH is transmitted in the last symbol of subframe #i, the UE transmits the SRS in the UL CC#1 in the last symbol of subframe #i. Example 4-2
As shown in Fig. 14, it is assumed that in a #i subframe, a UE needs to transmit PUCCHs in an UL CC#2 and transmit an SRS in an UL CC#1, the PUCCHs are one of PUCCH format 1/1 to /1 b/3, and an upper-layer configured parameter of AN-and-SRS-concurrent is FALSE. According to rule 4, UE transmits the PUCCHs in UL CC#2 in subframe #i when using a normal format, ie there are PUCCHs transmitted in the last symbol of subframe #i, and then according to rule 7, since there are PUCCHs transmitted in the last symbol of subframe #i, the UE withdraws and does not transmit the SRS in UL CC#1. Example 4-3
As shown in Fig. 15, it is assumed that in a #j subframe, a UE needs to transmit PUCCHs in an UL CC#2 and transmit an SRS in UL CC#2, and the PUCCHs are one of PUCCH format 1/1 to /1 b/3. Since subframe #j is not an SRS subframe that is configured by a cell-specific, primary uplink component carrier UL CC#2 upper layer, according to rule 4, the UE transmits the PUCCHs in the UL CC#2 in subframe #i when using a normal format, ie there are PUCCHs transmitted in the last symbol of subframe #j, and then according to rule 7, since there are PUCCHs transmitted in the last symbol of subframe #j, the UE withdraws and does not transmit SRS on UL CC#3. Modality 5 Example 5-1
As shown in Fig. 12, it is assumed that in a #i subframe, a UE needs to simultaneously transmit PUCCHs and a periodic SRS in a UL CC#2, and the PUCCHs are one of PUCCH 2/2a/2b format. According to rule 6, the UE transmits the PUCCHs in the subframe #i, and then according to rule 7, since there are PUCCHs transmitted in the last symbol of the subframe #i, the UE removes and does not transmit the SRS in the UL CC# two. Example 5-2
As shown in Fig. 12, it is assumed that in a subframe #i, a UE needs to simultaneously transmit PUCCHs and an aperiodic SRS in a UL CC#2, and the PUCCHs are PUCCH 2a or 2b formats or PUCCH 2 formats comprising ACK transmission /NACK According to rule 6, since the PUCCHs comprise ACK/NACK transmission, the UE transmits the PUCCHs in subframe #i, and then according to rule 8, since there are PUCCHs transmitted in the last symbol of subframe #i , the UE pulls out and does not transmit the SRS on UL CC#2. Example 5-3
As shown in Fig. 12, it is assumed that in a subframe #i, a UE needs to simultaneously transmit PUCCHs and an aperiodic SRS in a UL CC#2, and the PUCCHs are PUCCH 2a formats comprising no ACK/NACK transmission. According to rule 6, since the PUCCHs comprise no ACK/NACK, the UE transmits no PUCCH in subframe #i, and then according to rule 8, since no PUCCH is transmitted in the last symbol of subframe #i, the UE transmits the SRS at UL CC#2 in the last symbol of subframe #i. Modality 6 Example 6-1
As shown in Fig. 14, it is assumed that in a subframe #i, a UE needs to transmit PUCCHs in an UL CC#2 and at the same time transmit a periodic SRS in an UL CC#1, and the PUCCHs are one of format PUCCH 2/2a/2b. According to rule 6, the UE transmits the PUCCHs in the UL CC#2 in the subframe #i, and then according to rule 7, since there are PUCCHs transmitted in the last symbol of the subframe #i, the UE withdraws and does not transmit the SRS at UL CC#1. Example 6-2
As shown in Fig. 14, it is assumed that in a subframe #i, a UE needs to transmit PUCCHs in an UL CC#2 and at the same time transmit an aperiodic SRS in an UL CC#1, and the PUCCHs are PUCCH 2a formats or 2b or PUCCH 2 format comprising ACK/NACK transmission. According to rule 6, since all PUCCHs comprise ACK/NACK transmission, the UE transmits the PUCCHs in UL CC#2 in subframe #i, and then according to rule 7, since there are PUCCHs transmitted in the last symbol of subframe #i, UE withdraws and does not transmit the SRS on UL CC#1. Example 6-3
As shown in Fig. 13, it is assumed that in a subframe #i, a UE needs to transmit PUCCHs in an UL CC#2 and at the same time transmit an aperiodic SRS in an UL CC#1, and the PUCCHs are PUCCCH format 2 comprising no ACK/NACK transmission. According to rule 6, since the PUCCHs comprise no ACK/NACK transmission, the UE transmits no PUCCH in UL CC#2 in subframe #i, and then according to rule 8, since no PUCCH is transmitted in the last symbol of subframe #i, UE transmits the SRS at UL CC#1 in the last symbol of subframe #i. Modality 7
Example 7-1: When an upper-layer configured parameter of the UE's concurrent PUCCH-and-PUSCH-is TRUE, that is, a PUCCH and a PUSCH are allowed to be transmitted simultaneously, the UE largely uses the same processing modes than those of exemplary modes 1, 3, and 5 to determine transmission of the PUCCH, PUSCH, and SRS.
Example 7-2: When an upper-layer configured parameter of UE concurrent PUCCH-and-PUSCH-is FALSE, i.e. a PUCCH and a PUSCH are not allowed to be transmitted simultaneously, a UCI carried by a PUCCH is situated and transmitted in a PUSCH, in other words, only the PUSCH and PUSCH are simultaneously transmitted in the current subframe. At that time, the PUSCH and the SRS are simultaneously transmitted on the same component carrier, and thus, the UE uses the same processing mode as that of exemplary mode 1 to determine transmission of the PUSCH and the SRS. Modality 8
Example 8-1: when an upper-layer configured parameter of UE PUCCH-and-PUSCH-simultaneous is TRUE, that is, one PUCCH and one PUSCH are allowed to be transmitted simultaneously, if one PUCCH and one PUSCH to be transmitted in the subframe are on the same component carrier, and an SRS is on another component carrier, or the PUCCH, PUSCH, and SRS are on different component carriers, the UE largely uses the same processing modes as those of the exemplary embodiments. 2, 4 and 6 to determine transmission of PUCCH, PUSCH and SRS.
Example 8-2: when an upper-layer configured parameter of UE PUCCH-and-PUSCH-simultaneous is TRUE, that is, a PUCCH and a PUSCH are allowed to be transmitted simultaneously, if a PUCCH and an SRS to be transmitted in the subframe are on the same component carrier, and the PUSCH is on another component carrier, the UE uses broadly the same processing modes as that of exemplary modes 2, 3, and 5 to determine transmission of the PUCCH, PUSCH, and SRS .
Example 8-3: When an upper-layer configured parameter of the UE's concurrent PUCCH-and-PUSCH-to be TRUE, that is, a PUCCH and a PUSCH are allowed to be transmitted simultaneously, if a PUCCH and an SRS to be transmitted on the current subframe are on the same component carrier, and one PUCCH is on another component carrier, the UE broadly uses the same processing modes as that of exemplary modes 1, 4, and 6 to determine transmission of the PUCCH, the PUSCH, and the MRS.
Example 8-4: When an upper-layer configured parameter of UE concurrent PUCCH-and-PUSCH-is FALSE, that is, a PUCCH and a PUSCH are not allowed to be transmitted simultaneously, at that time, a UCI carried by the PUCCH is transmitted in PUSCH. If a PUSCH and an SRS to be transmitted in the current subframe are on different component carriers, the UE uses the same processing mode as that of exemplary mode 2 to determine transmission of the PUSCH and the SRS. If the PUSCH and the SRS to be transmitted by the current subframe are in the same subframe (for this scenario, the original PUSCH and the PUCCH are not necessarily on the same component carrier), the UE uses the same processing mode as those of the exemplary mode. 1 to determine PUSCH and SRS transmission. Modality 9
Example 9-1: When the UE is configured by upper layer signaling to allow to transmit a plurality of SRSs simultaneously, the UE transmits SRSs on the plurality of component carriers in the last symbol of the subframe.
Example 9-2: When the UE is configured by upper layer signaling not to allow to transmit a plurality of SRSs simultaneously, the UE transmits, according to a predefined priority principle, an SRS on a component carrier having a higher priority in the last symbol of the subframe.
Example 9-2-1: Assume that a UE uses priority principle 1 above when performing SRS selection, however it is assumed that UL CC#1/2/3 priorities are UL CC#2>UL CC# 1>UL CC#3 in sequence.
As shown in Fig. 16, the UE needs to transmit SRSs in UL CC#1 and UL CC#2 in the last symbol of subframe #i, but a higher layer configured signaling of the UE does not allow to transmit a plurality of SRSs simultaneously, and thus, according to the priority principle 1, on component carriers that need to transmit the SRSs, since the UL CC#2 has the highest priority, the UE transmits the SRS on the UL CC#2 in the last symbol of the subframe #i, and retrieves and does not transmit the SRS on UL CC#1, regardless of whether the SRS on UL CC#1 is a periodic SRS or an aperiodic SRS at this time.
Example 9-2-2: Assume that a UE uses priority principle 2 above when performing SRS selection.
As shown in Fig. 16, it is assumed that the UE needs to transmit an aperiodic SRS in an UL CC#1 and a periodic SRS in an UL CC#2 in the last symbol of a subframe #i, but higher-layer configured signaling of the UE does not allow to transmit a plurality of SRSs simultaneously, and thus, according to the priority principle 2, since the SRS in the UL CC#1 is an aperiodic SRS, the UE transmits the non-periodic SRS in the UL CC#1 in the last symbol of subframe #ie removes and does not transmit the SRS in UL CC#2.
Example 9-2-3: Assume that a UE uses the above priority 2 principle when performing SRS selection.
As shown in Fig. 17, it is assumed that the UE needs to transmit SRSs of the same type (both SRSs are periodic SRS or non-periodic SRS) in a UL CC#1 and a UL CC#3 in the last subframe symbol #i, but an upper layer configured signaling of the UE does not allow to transmit a plurality of SRSs simultaneously, and thus, according to the priority 2 principle, since the SRSs in UL CC#1 and UL CC#2 are of the same type, and at the same time there is a PUSCH to be transmitted in an UL CC#3, but no PUSCH is to be transmitted in UL CC#1, the UE transmits the SRS in UL CC#3 in the last symbol of subframe #i and does not transmits the SRS at UL CC#1.
Example 9-2-4: Assume that a UE uses priority principle 2 above when performing SRS selection.
As shown in Fig. 18, it is assumed that the UE needs to transmit SRSs of the same type (both SRSs are periodic SRS or non-periodic SRS) in a UL CC#1 and a UL CC#3 in the last subframe symbol #i, but an upper layer configured signaling of the UE does not allow to transmit a plurality of SRSs simultaneously, and thus, according to the priority 2 principle, since the SRSs in UL CC#1 and UL CC#2 are of the same type, and neither UL CC#1 nor UL CC#3 is a primary uplink component carrier, and at the same time, both have a PUSCH to be transmitted, at which time, the UE needs to choose an SRS in the UL CC#1 and UL CC#3 having a higher priority to transmit. Since the component carrier has priorities of UL CC#1>UL CC#3, the UE transmits the SRS in UL CC#1 in the last symbol of subframe #i and removes and does not transmit the SRS in UL CC#3.
Example 9-2-5: Assume that a UE uses priority principle 2 above when performing SRS selection.
As shown in Fig. 18, it is assumed that the UE needs to transmit SRSs of the same type (both are periodic SRS or non-periodic SRS) in a UL CC#1 and a UL CC#3 in the last symbol of a subframe #i, but an upper layer configured signaling of the UE does not allow to transmit a plurality of SRSs simultaneously, and so, according to priority principle 2, since the SRSs in UL CC#1 and UL CC#2 are of the same type, and neither UL CC#1 nor UL CC#3 is a primary uplink component carrier, and at the same time, both have a PUSCH to be transmitted, but it is assumed that the PUSCH in UL CC#1 carries a UCI, at which time, the UE transmits the SRS at UL CC#1 in the last symbol of subframe #i and removes and does not transmit the SRS at UL CC#3.
