[0019] Herein, exemplary embodiments are described in detail, and examples are shown in the drawings.

[0021] It should be noted that while various pieces of information may be described using terms such as first, second, third, etc., in the embodiments of this disclosure, this information should not be limited to these terms. These terms are used solely to distinguish information of the same type from one another. For example, without departing from the scope of the embodiments of this disclosure, first information may also be called second information, and similarly, second information may also be called first information. Depending on the context, the term “in the case” as used herein may be interpreted as “when…” or “if…” or “in response to deciding.”

[0022] Figure 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, the network device 12 including 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 forms of macro base stations, micro base stations, relay stations, access points, etc. In systems using different wireless access technologies, the name of the device that provides base station functionality may differ; for example, in Long Term Evolution (LTE) systems it is called an evolved base station (eNodeB, eNB), and in 5G NR systems it is called a next-generation base station (gNodeB, gNB). As communication technology evolves, the description of "base station" may also change. To facilitate the explanation of the embodiments of this disclosure, the above-mentioned devices that provide wireless communication functionality to the terminal 14 are collectively referred to as the network device 12.

[0024] Terminal 14 may include various handheld devices, in-vehicle devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various user equipment, mobile stations (MS), terminal devices, etc. For ease of explanation, the devices mentioned above are collectively referred to as terminals.

[0025] For example, there are two types of communication scenes between the network device 12 and the terminal 14: uplink communication and downlink communication. Uplink communication refers to the terminal 14 sending a signal to the network device 12, while downlink communication refers to the network device 12 sending a signal to the terminal 14.

[0026] Uplink PUSCH transmission is transmitted in the TRP direction of multiple base stations. In the R17 release of the Third Generation Partnership Project (3GPP), coordinated transmission was standardized, mainly using Time Division Multiplexing (TDM) transmission. This method repeatedly transmits the same information on PUSCH to different TRPs of base stations in time division, depending on different transmission occasions (TOs) in the time domain. This method has relatively low requirements for terminal functionality, does not require the ability to support simultaneous beam transmission, and has high transmission delay.

[0027] In the case of uplink, the channels that push channels intended for different TRPs actually pass through may have significantly different spatial characteristics, so the spatial reception parameters of push channels in different transmission directions are likely to be different.

[0028] The R18 enhancement objective aims to improve transmission reliability and throughput by enabling simultaneous coordinated transmission to multiple TRP directions via multiple antenna panels on a terminal, while also effectively reducing transmission delay in multi-TRP environments. However, this requires the terminal to have the capability to transmit multiple beams simultaneously. PUSCH transmission allows multi-antenna panels scheduled by a single Physical Downlink Control Channel (PDCCH), i.e., Single Downlink Control Information (S-DCI), to transmit to multiple TRPs.

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

[0030] PUSCH transmission is performed by a multi-antenna panel scheduled by different PDCCHs, i.e., Multi-Downlink Control Information (M-DCI), and transmitted to the TRP, as shown in Figure 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] TRP1 and TRP2 above are two TRPs in the same cell.

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

[0034] Figure 3 is a schematic diagram of an uplink push transmission based on a codebook provided in an exemplary embodiment of the present disclosure, the schematic diagram including a terminal 22 and a network device 24.

[0035] In the codebook-based uplink transmission process, the network device 24 first sends an SRS resource configuration to the terminal 22, which includes at least one SRS resource set and associated settings for each SRS resource. The terminal 22 then sends at least one SRS to the network device 24 based on the SRS resource configuration. The network device 24 obtains the channel status for each uplink channel based on the received at least one SRS, and further provides the terminal 22 with a DCI, which 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] Figure 4 is a schematic diagram of a non-codebook-based uplink transmission process provided by an exemplary embodiment of the present disclosure, the schematic diagram of 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. Network device 24 first transmits a Channel State Information-Reference Symbol (CSI-RS) and SRS resource configuration information to terminal 22, the SRS resource configuration including at least one SRS resource set and associated configurations for each SRS resource. Terminal 22 then calculates, based on the CSI-RS measurement results, through algorithms such as singular value decomposition, to obtain at least one available precoding matrix. Terminal 22 then transmits at least one SRS to network device 24 based on the SRS resource configuration. Network device 24 obtains the channel status for each uplink channel based on the received at least one SRS and further provides DCI to terminal 22, the DCI including at least SRI. Finally, terminal 22 determines which precoding matrix to use from the available precoding matrices and transmits a PUSCH to network device 24 based on the SRI and the precoding matrix to be used.

[0038] As can be seen from Figures 3 and 4 above, network devices need to send SRS resource settings to terminals in advance. In STxMP scenarios, there are two possible configuration methods.

[0039] The first possible SRS resource configuration method is as follows: The network device configures two SRS resource sets on the terminal, and these two SRS resource sets include a first SRS resource set and a second SRS resource set, with different SRS resource sets associated with different antenna panel information.

[0040] Both of these SRS resource sets are intended for use as either codebooks or non-codebooks.

[0041] Selectively, different antenna panel information is • Different antenna panels, the number of antenna panels may be two or four, and in the embodiments of this application, the default maximum number is two. • Different TRP, • Different TCI states, • Includes at least one of the different TOs.

[0042] In some embodiments, a first SRS resource set is associated with a first antenna panel of the terminal, and a 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 a network device, the first TRP transmits 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 transmits 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, which indicates the beam to be sent to a first TRP, and a second SRS resource set is associated with a second TCI state of the terminal, which indicates the beam to be sent to a second TRP.

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

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

[0047] The intended use of this SRS resource set is either a codebook or a non-codebook.

[0048] Selectively, different antenna panel information is • Different antenna panels, the number of antenna panels may be two or four, and in the embodiments of this application, the default maximum number is two. • Different TRP, • Different TCI states, • Includes at least one of the different TOs.

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

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

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

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

[0053] For the two types of SRS resource configuration methods described above, in STxMP scenes, the SRS resource set instruction field in DCI needs to be redesigned so that network devices can instruct terminals on the SRS resource set and SRI / TPMI fields that need to be associated in single-TRP (single-TRP, s-TRP) or multi-TRP (mutli-TRP, m-TRP) scenes. Figure 5 shows a schematic diagram of the DCI information fields provided by an exemplary embodiment of the present disclosure. In combination with Figure 5, the DCI includes a plurality of information fields, of which the fields relevant to this application include an SRS resource set instruction 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 non-codebook cases, the SRS resource set instruction field and two SRI fields are used, and for codebook cases, the SRS resource set instruction field, two SRI fields, and two TPMI fields are used. x1, x2, y1, and y2 are variable values.

[0054] In the current R17 protocol, the design of the meaning of each code point in the SRS resource set instruction field for cooperative transmission (asynchronous transmission) in the TDM transmission method is 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 in the SRS resource set instruction field is 00, a PUSCH is transmitted to TRP1 using s-TRP mode to instruct the terminal to associate with the first SRS resource set. In codebook-based transmission mode, the first SRI / TPMI field in DCI is used to obtain the SRI and TPMI to be used in this transmission. In non-codebook-based transmission mode, the first SRI / TPMI field in DCI is used to obtain the SRI to be used in this transmission. In this case, the second SRI / TPMI field is not used.

[0057] If the code point in the SRS resource set instruction field is 01, a PUSCH is transmitted to TRP2 using s-TRP mode to instruct the terminal to associate with the second SRS resource set. In codebook-based transmission mode, the first SRI / TPMI field in DCI is used to obtain the SRI and TPMI to be used in this transmission. In non-codebook-based transmission mode, the first SRI / TPMI field in DCI is used to obtain the SRI to be used in this transmission. In this case, the second SRI / TPMI field is not used.

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

[0059] If the code point of the SRS resource set instruction field is 11, the terminal is instructed to first transmit a PUSCH to TRP2 at the first TO using m-TRP mode to associate it with the second SRS resource set, and then transmit a PUSCH to TRP1 at the second TO to associate it with the first SRS resource set. In codebook-based transmission mode, the SRI and TPMI used when transmitted to TRP2 are obtained using the second SRI / TPMI field in DCI, and the SRI and TPMI used when transmitted to TRP1 are obtained using the first SRI / TPMI field in DCI. In non-codebook-based transmission mode, the SRI used when transmitted to TRP2 is obtained using the second SRI / TPMI field in DCI, and the SRI used when transmitted to TRP1 is obtained using the first SRI / TPMI field in DCI.

[0060] As can be seen from the analysis of Table 1, in 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, for example, they may have different numbers of ports corresponding to the maximum number of SRS resources they support, and they may have different maximum number of data layers they support. Considering this, at least for the non-codebook case, the number of SRS resources corresponding to different configurable SRS resource sets may actually differ based on the antenna panel's capabilities, and the x and y bits actually required may differ. Therefore, when y is greater than x, and the above code point is 01, the x bits are not used sufficiently. Based on this, the first and second SRI / TPMI fields must be designed with the same number of bits, and this same number of bits is the larger of the x and y bits. This occupies a large number of bits, and the DCI consumes a large number of resources.

[0061] Therefore, in order to solve the above-mentioned problems, this application proposes a different design concept.

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

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

[0064] Selectively, the first instruction field is the SRS resource set instruction field.

[0065] The possible design methods 1 are as follows:

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

[0067] For example, the value of the first indicator field includes a first code point, which is, for instance, 00 or 01.

[0068] If the value of the first instruction field is the first code point, the first code point indicates that the SRS resource set associated with the terminal's uplink data channel scheduling is the x-th SRS resource set, and the SRI / TPMI field used is the first SRI / TPMI field. That is, for codebook-corresponding uplink transmissions, the SRI / TPMI field used is the first SRI / TPMI field, and for non-codebook-corresponding uplink transmissions, the SRI field used is the first SRI field. Exemplarily, if the first code point is 00, then x is 1, and if the first code point is 01, then x is 2.

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

[0070] As an example, some of the code points in the SRS resource set instruction field based on the design concept are shown in Table 2 below. [Table 2]

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

[0072] The possible design methods 2 are as follows:

[0073] In design method 2, instead of continuing to use the design concepts in Table 1, the choice of which SRI / TPMI field to use depends on which SRS resource set the s-TRP mode is associated with.

[0074] For example, the value of the first indicator field includes a second code point, which is, for instance, 01.

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

[0076] As an example, some of the code points in the SRS resource set instruction field based on the design concept are shown in Table 3 below. [Table 3]

[0077] Of course, the above example illustrates the case where a network device configures two SRS resource sets on a terminal. If a network device configures one SRS resource set on a terminal, that one SRS resource set includes a first SRS resource subset and a second SRS resource subset.

[0078] The possible design methods 3 are as follows:

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

[0080] For example, the value of the first indicator field includes a first code point, which is, for instance, 00 or 01.

[0081] If the value of the first instruction field is the first code point, the first code point indicates that the associated SRS resource subset when the terminal's uplink data channel scheduling is an uplink transmission from a single antenna panel to a single TRP is the x-th SRS resource subset, and the SRI / TPMI field used is the first SRI / TPMI field. That is, for uplink transmissions corresponding to a codebook, the SRI / TPMI field used is the first SRI / TPMI field, and for uplink transmissions not corresponding to a codebook, the SRI field used is the first SRI field. Exemplarily, if the first code point is 00, then x is 1, and if the first code point is 01, then x is 2.

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

[0083] As an example, some of the code points in the SRS resource subset instruction field based on the design concept are shown in Table 4 below. [Table 4]

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

[0085] The possible design methods 4 are as follows:

[0086] In design method 4, instead of continuing to use the design concepts in Table 1, the choice of which SRI / TPMI field to use depends on which SRS resource subset the s-TRP mode is associated with.

[0087] For example, the value of the first indicator field includes a second code point, which is, for instance, 01.

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

[0089] As an example, some of the code points in the SRS resource subset instruction field based on the design concept are shown in Table 5 below.

[0090] [Table 5]

[0091] Selectively, the uplink data channel is PUSCH.

[0092] As described above, the method provided by this embodiment allows for a reduction in the number of bits that the DCI needs to occupy when, in an STxMP scene, the terminal is scheduled to use uplink transmission from a single antenna panel to a single TRP, by using any one of the above-mentioned SRS resource set instruction field design schemes.

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

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

[0095] Selectively, the first instruction field is the SRS resource set instruction field.

[0096] The possible design methods 1 are as follows:

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

[0098] For example, the value of the first indicator field includes a first code point, which is, for instance, 00 or 01.

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

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

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

[0102] The possible design method 2 is as follows:

[0103] In design method 2, instead of continuing to use the design concepts in Table 1, the choice of which SRI / TPMI field to use depends on which SRS resource set the s-TRP mode is associated with.

[0104] For example, the value of the first indicator field includes a second code point, which is, for instance, 01.

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

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

[0107] Of course, the above example illustrates the case where a network device configures two SRS resource sets on a terminal. If a network device configures one SRS resource set on a terminal, that one SRS resource set includes a first SRS resource subset and a second SRS resource subset.

[0108] The possible design methods 3 are as follows:

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

[0110] For example, the value of the first indicator field includes a first code point, which is, for instance, 00 or 01.

[0111] If the value of the first instruction field is the first code point, the first code point indicates that the associated SRS resource subset when the terminal's uplink data channel scheduling is an uplink transmission from a single antenna panel to a single TRP is the x-th SRS resource subset, and the SRI / TPMI field used is the first SRI / TPMI field; that is, for an uplink transmission corresponding to a codebook, the SRI / TPMI field used is the first SRI / TPMI field, and for an uplink transmission not corresponding to a codebook, the SRI field used is the first SRI field. Exemplarily, if the first code point is 00, then x is 1, and if the first code point is 01, then x is 2.

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

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

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

[0115] The possible design methods 4 are as follows:

[0116] In design method 4, instead of continuing to use the design concepts in Table 1, the choice of which SRI / TPMI field to use depends on which SRS resource subset the s-TRP mode is associated with.

[0117] For example, the value of the first indicator field includes a second code point, which is, for instance, 01.

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

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

[0120] Selectively, the uplink data channel is PUSCH.

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

That is, for codebook-corresponding uplink transmissions, the SRI / TPMI field used is the first SRI / TPMI field, and for non-codebook-corresponding uplink transmissions, the SRI field used is the first SRI field. Here, the first SRI / TPMI field is fixedly associated as the first SRS resource set with the SRS resource set containing the largest number of SRS resources among all SRS resource sets, the number of bits corresponding to the first SRI field is greater than or equal to the number of bits in the second SRI field, and x is 1 or 2. Exemplaryly, if the first code point is 00, x is 1, and if the first code point is 01, x is 2.
