[0022] FIG. 1 is a schematic diagram of a communication system provided by an exemplary embodiment of the present disclosure, which may include a network device 12 and a terminal 14, where the network device 12 includes TRP1 and TRP2.

[0023] The network device 12 may be a base station, which is a device that provides wireless communication functionality for the terminal 14. The base station may include various types of macro base stations, micro base stations, relay stations, access points, etc. In systems using different radio access technologies, the name of a device having base station functionality may differ. For example, in a Long Term Evolution (LTE) system, it is called an evolved base station (eNodeB, eNB), and in a 5G NR system, it is called a next-generation base station (gNodeB, gNB). As communication technologies evolve, the description of a "base station" may also change. To facilitate the description of the embodiments of the present disclosure, the above devices that provide wireless communication functionality to the terminal 14 will be collectively referred to as network device 12.

[0024] The terminals 14 may include various handheld devices, in-vehicle devices, wearable devices, computing devices, or other processing devices connected to wireless modems with wireless communication capabilities, as well as various user equipment, mobile stations (MS), terminal devices, etc. For ease of explanation, the devices referred to above will be collectively referred to as terminals.

[0025] Illustratively, there are two types of communication scenarios between the network device 12 and the terminal 14: an uplink communication scenario and a downlink communication scenario. The uplink communication scenario refers to the terminal 14 transmitting a signal to the network device 12, and the downlink communication scenario refers to the network device 12 transmitting a signal to the terminal 14.

[0026] Uplink PUSCH transmission is transmitted toward the TRPs of multiple base stations. In Release R17 of the Third Generation Partnership Project (3GPP), cooperative transmission was mainly standardized using the Time Division Multiplexing (TDM) transmission method, in which the same information on the PUSCH is repeatedly transmitted to different TRPs of the base station in time division according to different transmission occasions (TOs) in the time domain. This method has relatively low requirements for terminal capabilities, does not require the ability to support simultaneous beam transmission, and has a large transmission delay.

[0027] In the uplink, the spatial reception parameters of the PUSCH channels for different transmission directions may be different, since the channels through which the PUSCH channels for different TRPs actually pass may have significantly different spatial characteristics.

[0028] The R18 enhancement targets simultaneous coordinated transmission to multiple TRP directions via multiple antenna panels of a terminal, which can improve transmission reliability and throughput and effectively reduce transmission delay in multi-TRP. However, this requires the terminal to have the ability to transmit multiple beams simultaneously. PUSCH transmission can be transmitted to multiple TRPs by multiple antenna panels scheduled by a single Physical Downlink Control Channel (PDCCH), i.e., a single downlink control information (S-DCI).

[0029] As shown in Fig. 1, precoding matrix 1 and precoding matrix 2 are directly or indirectly scheduled to a terminal via one DCI. Terminal 14 transmits one-layer or multiple-layer uplink data to TRP1 using antenna panel 1 based on precoding matrix 1. Terminal 14 transmits one-layer or multiple-layer uplink data to TRP1 using antenna panel 2 based on precoding matrix 2.

[0030] The PUSCH is transmitted to the TRP by a multi-antenna panel scheduled by a different PDCCH, i.e., Multi-Downlink Control Information (M-DCI), as shown in FIG. 2.

[0031] TRP1 transmits a first DCI to terminal 14 via PDCCH1 and schedules terminal 14 to transmit PUSCH1 to TRP1 using antenna panel 1, and TRP2 transmits a second DCI to terminal 14 via PDCCH2 and schedules terminal 14 to transmit PUSCH2 to TRP2 using antenna panel 2.

[0032] The above TRP1 and TRP2 are two TRPs in the same cell.

[0033] In the STxMP scenario, the process of uplink transmission includes codebook-based uplink transmission and non-codebook-based uplink transmission.

[0034] FIG. 3 is a schematic diagram of uplink PUSCH transmission based on a codebook provided by an exemplary embodiment of the present disclosure, which includes a terminal 22 and a network device 24 .

[0035] In the uplink transmission process based on the codebook, the network device 24 first sends an SRS resource configuration to the terminal 22, where the SRS resource configuration includes at least one SRS resource set and an associated configuration for each SRS resource; then, the terminal 22 sends at least one SRS to the network device 24 based on the SRS resource configuration; the network device 24 obtains the channel conditions of each uplink channel based on the received at least one SRS, and further provides DCI to the terminal 22, where the DCI includes at least an SRI and a TPMI; finally, the terminal 22 sends a PUSCH to the network device 24 based on the TPMI and SRI.

[0036] FIG. 4 is a schematic diagram of a non-codebook-based uplink transmission process provided by an exemplary embodiment of the present disclosure, which includes a terminal 22 and a network device 24 .

[0037] In a non-codebook-based uplink transmission process, the precoding matrix is ​​not limited to a fixed set of candidates. The network device 24 first transmits a channel state information reference symbol (CSI-RS) and SRS resource configuration information to the terminal 22, where the SRS resource configuration includes at least one SRS resource set and an associated configuration for each SRS resource. The terminal 22 then obtains at least one usable precoding matrix by self-calculating it through an algorithm such as singular value decomposition based on the CSI-RS measurement results. The terminal 22 then transmits at least one SRS to the network device 24 based on the SRS resource configuration. The network device 24 obtains the channel conditions of each uplink channel based on the received at least one SRS and further provides DCI to the terminal 22, where the DCI includes at least SRI. Finally, the terminal 22 determines a currently used precoding matrix from the available precoding matrices and transmits a PUSCH to the network device 24 based on the SRI and the currently used precoding matrix.

[0038] As can be seen from Figure 3 and Figure 4 above, the network device needs to send SRS resource configuration to the terminal in advance. In the STxMP scenario, there may be two possible configuration methods:

[0039] A first possible SRS resource configuration manner is as follows: the network device configures two SRS resource set configurations in the terminal, the two SRS resource sets include a first SRS resource set and a second SRS resource set, and different SRS resource sets are associated with different antenna panel information.

[0040] The two SRS resource sets can be used for either codebook or non-codebook purposes.

[0041] Optionally, different antenna panel information may be Different antenna panels, the number of antenna panels can be two or four, and in the present embodiment the default maximum number is two; · Different TRPs, Different TCI states, · Different TOs.

[0042] In some embodiments, the first SRS resource set is associated with a first antenna panel of the terminal, and the second SRS resource set is associated with a second antenna panel of the terminal.

[0043] In some embodiments, a first SRS resource set is associated with a first TRP of the network device, the first TRP transmitting the DCI to a first antenna panel, and a second SRS resource set is associated with a second TRP of the network device, the second TRP transmitting the DCI to a second antenna panel.

[0044] In some embodiments, a first SRS resource set is associated with a first TCI state of the terminal, the first TCI state indicating a beam transmitted to a first TRP, and a second SRS resource set is associated with a second TCI state of the terminal, the second TCI state indicating a beam transmitted to a second TRP.

[0045] In some embodiments, the first SRS resource set is associated with a first TO of the terminal, and the first TO transmits the SRS to a first TRP, and the second SRS resource set is associated with a second TO of the terminal, and the second TO transmits the SRS to a second TRP.

[0046] A second possible SRS resource configuration manner is as follows: the network device configures the terminal with one SRS resource set configuration, the SRS resource set includes a first SRS resource subset and a second SRS resource subset, and different SRS resource subsets are associated with different antenna panel information.

[0047] The SRS resource set can be used for codebook or non-codebook purposes.

[0048] Optionally, different antenna panel information may be Different antenna panels, the number of antenna panels may be two or four, and in the present embodiment, the default maximum number is two; · Different TRPs, Different TCI states, · Different TOs.

[0049] In some embodiments, the first SRS resource subset is associated with a first antenna panel of the terminal, and the second SRS resource subset is associated with a second antenna panel of the terminal.

[0050] In some embodiments, the first SRS resource subset is associated with a first TRP of the network device, the first TRP transmitting the DCI to a first antenna panel, and the second SRS resource subset is associated with a second TRP of the network device, the second TRP transmitting the DCI to a second antenna panel.

[0051] In some embodiments, the first SRS resource subset is associated with a first TCI state of the terminal, the first TCI state indicating a beam transmitted to a first TRP, and the second SRS resource subset is associated with a second TCI state of the terminal, the second TCI state indicating a beam transmitted to a second TRP.

[0052] In some embodiments, the first SRS resource subset is associated with a first TO of the terminal, and the first TO transmits the SRS to a first TRP, and the second SRS resource subset is associated with a second TO of the terminal, and the second TO transmits the SRS to a second TRP.

[0053] For the above two SRS resource configuration methods, in the STxMP scenario, the SRS resource set indication field in the DCI needs to be redesigned so that the network device can indicate to the terminal the SRS resource set and SRI / TPMI fields that need to be associated in the single-TRP (s-TRP) or multi-TRP (m-TRP) scenario. Figure 5 shows a schematic diagram of a DCI information field provided by an exemplary embodiment of the present disclosure. In combination with Figure 5, the DCI includes multiple information fields, among which the fields relevant to the present application include an SRS resource set indication field (2 bits), a first SRI field (x1 bit), a second SRI field (x2 bits), a first TPMI field (y1 bit), and a second TPMI field (y2 bits). For the non-codebook scenario, the SRS resource set indication field and two SRI fields are used, and for the codebook scenario, the SRS resource set indication field, two SRI fields, and two TPMI fields are used. x1, x2, y1 and y2 are variable values.

[0054] In the current R17 protocol, for cooperative transmission (non-simultaneous transmission) in the TDM transmission method, the meaning of each code point in the SRS resource set indication field is designed as shown in Table 1 below. [Table 1]

[0055] The meaning of each code point in Table 1 is as follows:

[0056] If the code point of the SRS resource set indication field is 00, the UE is instructed to transmit a PUSCH on TRP1 using s-TRP mode to associate it with the first SRS resource set. In the codebook-based transmission mode, the first SRI / TPMI field in the DCI is used to obtain the SRI and TPMI used for this transmission, and in the non-codebook-based transmission mode, the first SRI / TPMI field in the DCI is used to obtain the SRI used for this transmission. At this time, the second SRI / TPMI field is not used.

[0057] If the code point of the SRS resource set indication field is 01, the UE is instructed to transmit the PUSCH to TRP2 using s-TRP mode and associate it with the second SRS resource set. In the codebook-based transmission mode, the first SRI / TPMI field in the DCI is used to obtain the SRI and TPMI used for this transmission, and in the non-codebook-based transmission mode, the first SRI / TPMI field in the DCI is used to obtain the SRI used for this transmission. At this time, the second SRI / TPMI field is not used.

[0058] When the code point of the SRS resource set indication field is 10, the m-TRP mode is used to instruct the terminal to first transmit a PUSCH to TRP1 in the first TO to associate it with the first SRS resource set, and then transmit a PUSCH to TRP2 in the second TO to associate it with the second SRS resource set. In the codebook-based transmission mode, the first SRI / TPMI field in the DCI is used to obtain the SRI and TPMI used when transmitted to TRP1, and the second SRI / TPMI field in the DCI is used to obtain the SRI and TPMI used when transmitted to TRP2. In the non-codebook-based transmission mode, the first SRI / TPMI field in the DCI is used to obtain the SRI used when transmitted to TRP1, and the second SRI / TPMI field in the DCI is used to obtain the SRI used when transmitted to TRP2.

[0059] When the code point of the SRS resource set indication field is 11, the m-TRP mode is used to instruct the terminal to first transmit a PUSCH to TRP2 in the first TO to associate it with the second SRS resource set, and then transmit a PUSCH to TRP1 in the second TO to associate it with the first SRS resource set. In the codebook-based transmission mode, the second SRI / TPMI field in the DCI is used to obtain the SRI and TPMI used when transmitting to TRP2, and the first SRI / TPMI field in the DCI is used to obtain the SRI and TPMI used when transmitting to TRP1. In the non-codebook-based transmission mode, the second SRI / TPMI field in the DCI is used to obtain the SRI used when transmitting to TRP2, and the first SRI / TPMI field in the DCI is used to obtain the SRI used when transmitting to TRP1.

[0060] As can be seen from Table 1, in the s-TRP mode, the first SRI / TPMI field is used regardless of whether it is associated with the first or second SRS resource set. Different antenna panels may have different capabilities, such as different numbers of ports corresponding to the maximum supported SRS resources and different maximum supported data layers. Considering this, at least for the non-codebook case, the number of SRS resources corresponding to different configurable SRS resource sets may differ based on the antenna panel's capabilities, and the actual required x and y bits may differ. Therefore, when y is greater than x, if the code point is 01, x bits are not fully used. Based on this, the first and second SRI / TPMI fields can only be designed to have the same number of bits, which is the larger of x and y bits. This occupies a large number of bits, resulting in DCI consuming a large number of resources.

[0061] Therefore, the present application proposes a different design concept to solve the above problems.

[0062] FIG. 6 shows a flowchart of an information indication method provided by an exemplary embodiment of the present disclosure, which is applied to the terminal of the communication system shown in FIG. 1, and includes the following step 602.

[0063] In step 602, the terminal receives a DCI carrying a first indication field, and some code points in the first indication field are associated with an STxMP configuration scheduled by a single DCI and indicate an SRS resource set and an SRI / TPMI field associated when the terminal's uplink data channel scheduling is uplink transmission from a single antenna panel to a single TRP.

[0064] Optionally, the first indication field is an SRS resource set indication field.

[0065] Possible design method 1 is as follows:

[0066] Design method 1 continues to use the design concept of Table 1, ie, uses the first SRI / TPMI field regardless of which SRS resource set the s-TRP mode is associated with.

[0067] Illustratively, the value of the first indication field includes a first code point, for example, the first code point is 00 or 01.

[0068] If the value of the first indication field is the first code point, the first code point indicates that when the uplink data channel scheduling of the terminal is uplink transmission from a single antenna panel to a single TRP, the associated SRS resource set is the x-th SRS resource set and the used SRI / TPMI field is the first SRI / TPMI field. That is, for uplink transmission corresponding to a codebook, the used SRI / TPMI field is the first SRI / TPMI field, and for uplink transmission corresponding to a non-codebook, the used SRI field is the first SRI field. Exemplarily, if the first code point is 00, x is 1, and if the first code point is 01, x is 2.

[0069] Here, the first SRI / TPMI field is fixedly associated as the first SRS resource set with the SRS resource set that includes the largest number of SRS resources among all SRS resource sets, and the number of bits corresponding to the first SRI field is equal to or greater than the number of bits of the second SRI field.

[0070] For example, some code points in the SRS resource set indication field based on this design concept are shown in Table 2 below. [Table 2]

[0071] Here, the first SRS resource set is, by default, an SRS resource set (which may be associated with TRP1 or may be associated with TRP2, not limited here) that has the largest number of SRS resources among all SRS resource sets, and the number of bits corresponding to the first SRI field is equal to or greater than the number of bits of the second SRI field.

[0072] Possible design method 2 is as follows:

[0073] In Design Method 2, rather than continuing to use the design concepts in Table 1, the SRI / TPMI fields used relate to which SRS resource set an s-TRP mode is associated with.

[0074] Illustratively, the value of the first indication field includes a second code point, for example, 01.

[0075] If the value of the first indication field is the second code point, the second code point indicates that when the terminal is scheduled for uplink transmission from a single antenna panel to a single TRP in the uplink data channel, the SRS resource set used is the second SRS resource set and the SRI / TPMI field used is the second SRI / TPMI field, that is, for uplink transmission corresponding to a codebook, the SRI / TPMI field used is the second SRI / TPMI field, and for uplink transmission corresponding to a non-codebook, the SRI field used is the second SRI field.

[0076] For example, some code points in the SRS resource set indication field based on this design concept are shown in Table 3 below. [Table 3]

[0077] Of course, the above example takes the case where a network device configures two SRS resource sets for a terminal as an example, and if the network device configures one SRS resource set for a terminal, the one SRS resource set includes a first SRS resource subset and a second SRS resource subset.

[0078] Possible design method 3 is as follows:

[0079] Design method 3 continues to use the design concept of Table 1, ie, uses the first SRI / TPMI field regardless of which SRS resource subset the s-TRP mode is associated with.

[0080] Illustratively, the value of the first indication field includes a first code point, for example, the first code point is 00 or 01.

[0081] If the value of the first indication field is the first code point, the first code point indicates that when the uplink data channel scheduling of the terminal is uplink transmission from a single antenna panel to a single TRP, the associated SRS resource subset is the x-th SRS resource subset and the used SRI / TPMI field is the first SRI / TPMI field. That is, for uplink transmission corresponding to a codebook, the used SRI / TPMI field is the first SRI / TPMI field, and for uplink transmission corresponding to a non-codebook, the used SRI field is the first SRI field. Exemplarily, if the first code point is 00, x is 1, and if the first code point is 01, x is 2.

[0082] Here, the first SRI / TPMI field is fixedly associated as the first SRS resource subset with the SRS resource subset that includes the largest number of SRS resources among all the SRS resource subsets, and the number of bits corresponding to the first SRI field is equal to or greater than the number of bits of the second SRI field.

[0083] For example, some code points in the SRS resource subset indication field based on this design concept are shown in Table 4 below. [Table 4]

[0084] Here, the first SRS resource subset is, by default, one SRS resource subset (which may be associated with TRP1, may be associated with TRP2, and is not limited here) that has the largest number of SRS resources among all SRS resource subsets, and the number of bits corresponding to the first SRI field is equal to or greater than the number of bits of the second SRI field.

[0085] Possible design method 4 is as follows:

[0086] In Design Scheme 4, rather than continuing to use the design concepts in Table 1, which SRI / TPMI fields to use relates to which SRS resource subset an s-TRP mode is associated with.

[0087] Illustratively, the value of the first indication field includes a second code point, for example, 01.

[0088] If the value of the first indication field is the second code point, the second code point indicates that when the terminal is scheduled for uplink transmission from a single antenna panel to a single TRP in the uplink data channel, the SRS resource subset used is the second SRS resource subset and the SRI / TPMI field used is the second SRI / TPMI field, that is, for uplink transmission corresponding to a codebook, the SRI / TPMI field used is the second SRI / TPMI field, and for uplink transmission corresponding to a non-codebook, the SRI field used is the second SRI field.

[0089] For example, some code points in the SRS resource subset indication field based on this design concept are shown in Table 5 below.

[0090] [Table 5]

[0091] Optionally, the uplink data channel is a PUSCH.

[0092] As described above, the method provided by this embodiment is that in an STxMP scenario, when a terminal is scheduled to use uplink transmission from a single antenna panel to a single TRP, by using any one of the above-mentioned several SRS resource set indication field design methods, the number of bits that DCI needs to occupy can be reduced.

[0093] FIG. 7 shows a flowchart of an information indication method provided by an exemplary embodiment of the present disclosure, which is applied to a network device of the communication system shown in FIG. 1, and includes the following step 702:

[0094] In step 702, the network device sends a DCI carrying a first indication field to the terminal, where some code points in the first indication field are associated with an STxMP configuration scheduled by a single DCI and indicate an SRS resource set and an SRI / TPMI field associated when the uplink data channel scheduling of the terminal is uplink transmission from a single antenna panel to a single TRP.

[0095] Optionally, the first indication field is an SRS resource set indication field.

[0096] Possible design method 1 is as follows:

[0097] Design method 1 continues to use the design concept of Table 1, ie, uses the first SRI / TPMI field regardless of which SRS resource set the s-TRP mode is associated with.

[0098] Illustratively, the value of the first indication field includes a first code point, for example, the first code point is 00 or 01.

[0099] If the value of the first indication field is a first code point, the first code point indicates that when the uplink data channel scheduling of the terminal is uplink transmission from a single antenna panel to a single TRP, the associated SRS resource set is the x-th SRS resource set and the used SRI / TPMI field is the first SRI / TPMI field, i.e., for uplink transmission corresponding to a codebook, the used SRI / TPMI field is the first SRI / TPMI field, and for uplink transmission corresponding to a non-codebook, the used SRI field is the first SRI field. Exemplarily, if the first code point is 00, x is 1, and if the first code point is 01, x is 2.

[0100] Here, the first SRI / TPMI field is fixedly associated as the first SRS resource set with the SRS resource set that includes the largest number of SRS resources among all SRS resource sets, and the number of bits corresponding to the first SRI field is equal to or greater than the number of bits of the second SRI field.

[0101] For example, some code points in the SRS resource set indication field based on this design concept are shown in Table 2 above, where the first SRS resource set is, by default, an SRS resource set with the largest number of SRS resources among all SRS resource sets (it may be associated with TRP1 or TRP2, not limited here), and the number of bits corresponding to the first SRI field is equal to or greater than the number of bits of the second SRI field.

[0102] Possible design method 2 is as follows:

[0103] In Design Method 2, rather than continuing to use the design concepts in Table 1, which SRI / TPMI fields to use relates to which SRS resource set an s-TRP mode is associated with.

[0104] Illustratively, the value of the first indication field includes a second code point, for example, 01.

[0105] If the value of the first indication field is the second code point, the second code point indicates that when the terminal is scheduled for uplink transmission from a single antenna panel to a single TRP in the uplink data channel, the SRS resource set used is the second SRS resource set and the SRI / TPMI field used is the second SRI / TPMI field, that is, for uplink transmission corresponding to a codebook, the SRI / TPMI field used is the second SRI / TPMI field, and for uplink transmission corresponding to a non-codebook, the SRI field used is the second SRI field.

[0106] For example, some code points in the SRS resource set indication field based on this design concept are shown in Table 3 above.

[0107] Of course, the above example describes an example in which a network device configures two SRS resource sets for a terminal, and if the network device configures one SRS resource set for a terminal, the one SRS resource set includes a first SRS resource subset and a second SRS resource subset.

[0108] Possible design method 3 is as follows:

[0109] Design method 3 continues to use the design concept of Table 1, ie, uses the first SRI / TPMI field regardless of which SRS resource subset the s-TRP mode is associated with.

[0110] Illustratively, the value of the first indication field includes a first code point, for example, the first code point is 00 or 01.

[0111] If the value of the first indication field is a first code point, the first code point indicates that when the uplink data channel scheduling of the terminal is uplink transmission from a single antenna panel to a single TRP, the associated SRS resource subset is the x-th SRS resource subset and the used SRI / TPMI field is the first SRI / TPMI field, i.e., for uplink transmission corresponding to a codebook, the used SRI / TPMI field is the first SRI / TPMI field, and for uplink transmission corresponding to a non-codebook, the used SRI field is the first SRI field. Exemplarily, if the first code point is 00, x is 1, and if the first code point is 01, x is 2.

[0112] Here, the first SRI / TPMI field is fixedly associated as the first SRS resource subset with the SRS resource subset that includes the largest number of SRS resources among all the SRS resource subsets, and the number of bits corresponding to the first SRI field is equal to or greater than the number of bits of the second SRI field.

[0113] For example, some code points in the SRS resource subset indication field based on this design concept are shown in Table 4 above.

[0114] Here, the first SRS resource subset is, by default, one SRS resource subset (which may be associated with TRP1, may be associated with TRP2, and is not limited here) that has the largest number of SRS resources among all SRS resource subsets, and the number of bits corresponding to the first SRI field is equal to or greater than the number of bits of the second SRI field.

[0115] Possible design method 4 is as follows:

[0116] In Design Scheme 4, rather than continuing to use the design concepts in Table 1, which SRI / TPMI fields to use relates to which SRS resource subset an s-TRP mode is associated with.

[0117] Illustratively, the value of the first indication field includes a second code point, for example, 01.

[0118] If the value of the first indication field is the second code point, the second code point indicates that when the terminal is scheduled for uplink transmission from a single antenna panel to a single TRP in the uplink data channel, the SRS resource subset used is the second SRS resource subset and the SRI / TPMI field used is the second SRI / TPMI field, that is, for uplink transmission corresponding to a codebook, the SRI / TPMI field used is the second SRI / TPMI field, and for uplink transmission corresponding to a non-codebook, the SRI field used is the second SRI field.

[0119] For example, some code points in the SRS resource subset indication field based on this design concept are shown in Table 5 above.

[0120] Optionally, the uplink data channel is a PUSCH.

[0121] As described above, the method provided by this embodiment is that in an STxMP scenario, when a terminal is scheduled to use uplink transmission from a single antenna panel to a single TRP, by using any one of the above-mentioned several SRS resource set indication field design methods, the number of bits that DCI needs to occupy can be reduced.
