Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0142] In the R16 uplink 2-port and 4-port uplink full power transmission (ULFPTx) discussion, multiple full power (maximum power, or maximum transmit power) transmission modes were defined to achieve full power transmission. First, based on the different power amplifier (PA) architectures of the UE, three different UE capabilities were defined for power class 3 UEs (that is, UEs with full power, maximum power, or maximum transmit power of 23dBm). The following uses a 2-port UE as an example:

[0143] UE capability 1: Each RF link is configured with a PA with a full-rated output power, for example, PA = [23, 23] dBm. This means that in a UE with this capability, each RF link can be configured with a PA with a rated power (23 dBm) equal to the UE's maximum power.

[0144] UE capability 2: Each RF link is not configured with a PA with rated power output, for example, PA = [20, 20]dBm;

[0145] UE capability 3: Some RF links are configured with PAs with rated power output, for example, PA = [23, 20] dBm.

[0146] The RF link may also be referred to as a transmit (TX) link, and the configurable PA of each RF link may also be understood as the configurable rated power of the antenna port of the UE.

[0147] In response to the above three UE capabilities, R15 proposes three full-power transmission modes, namely Mode 0, Mode 1 and Mode 2 below.

[0148] Mode 0: In Mode 0, the physical uplink shared channel (PUSCH) power scaling factor is fixed to 1, corresponding to UE capability 1. Since each PA can transmit at full power, full power transmission can be achieved even for non-coherent codewords. For example, for codeword [1,0] T , full power can be transmitted through the first PA alone.

[0149] Mode 1: In Mode 1, full power transmission is achieved by introducing codewords that can support full power transmission based on the original "codebook subset restriction". For example, for a 4-port 2-layer non-coherent codebook, a 4-port 2-layer partially coherent codeword is introduced. Among them, "1 / 2" in this part of the coherent codeword is the coefficient of the codeword. Mode 2: In Mode 2, full power transmission of a single port can be achieved through port virtualization. Among them, the implementation of port virtualization involves the modification of the sounding reference signal (SRS) resource configuration method and the modification of the PUSCH power control rule. For example, for a 4-port UE, the power information of its antenna port is PA = [20, 20, 17, 17] dBm. The base station can configure 2-port SRS resources. The UE can obtain two virtual ports with corresponding powers of [23, 20] dBm through SRS port virtualization. At this time, the codeword [1, 0] is used. T Full power uplink transmission can be achieved.

[0150] It should be noted that the codewords mentioned in the following embodiments of the present disclosure do not show their corresponding coefficients, and the present disclosure does not limit the coefficients of the codewords.

[0151] Figure 2 is an interactive diagram of a method for processing information according to an embodiment of the present disclosure. As shown in Figure 2, the embodiment of the present disclosure relates to a method for processing information, and the method includes:

[0152] Step S2101 , the network device 102 sends fifth information to the terminal 101 .

[0153] In some embodiments, the fifth information is used to indicate an SRS resource set, where the SRS resource set includes one or more SRS resources with different numbers of SRS ports.

[0154] In some embodiments, the fifth information may indicate one SRS resource set, or may indicate multiple SRS resource sets.

[0155] In some embodiments, the SRS resource set may include 2 SRS resources, 4 SRS resources, or 8 SRS resources, etc., which is not limited in the present disclosure.

[0156] In some embodiments, for an 8-port UE, the SRS resource set includes 2 SRS resources, and the two SRS resources can be respectively configured as an SRS resource for 1 port and an SRS resource for 2 ports; or, the two SRS resources can be respectively configured as an SRS resource for 1 port and an SRS resource for 4 ports; or, the two SRS resources can be respectively configured as an SRS resource for 1 port and an SRS resource for 8 ports, and so on. This disclosure does not limit this.

[0157] In some embodiments, the terms "SRS port," "antenna port," "port," etc. may be interchangeable.

[0158] In some embodiments, for an 8-port UE, SRS resources are centrally configured as 4 or 8 SRS resources, and then multiple SRS resources can be configured as 1 or 2 ports respectively; or, multiple SRS resources can be configured as 1 or 4 ports respectively; or, multiple SRS resources can be configured as 1 or 8 ports respectively; or, multiple SRS resources can be configured as 1, 2 or 8 ports respectively; or, multiple SRS resources can be configured as 1, 2 or 4 ports respectively; or, multiple SRS resources can be configured as 1, 4 or 8 ports respectively; or, multiple SRS resources can be configured as 1, 2, 4 or 8 ports respectively, and so on. This disclosure does not limit this.

[0159] In some embodiments, the number of SRS resource ports in the SRS resource set is the same, and the multiple SRS resources correspond to different spatial filter parameters.

[0160] For example, if the number of ports of SRS#1 and SRS#2 in the SRS resource set is both 2, then SRS#1 and SRS#2 may correspond to different spatial filters, that is, SRS#1 or SRS#2 corresponds to different beam directions.

[0161] In some embodiments, the network device 102 may determine and indicate to the terminal 101 the spatial filter corresponding to each SRS resource.

[0162] In some embodiments, the terminal 101 may receive a spatial filter corresponding to each SRS resource indicated by the network device.

[0163] In some embodiments, the terms "spatial filter", "spatial filtering parameters", "spatial filter parameters", etc. can be used interchangeably.

[0164] In some embodiments, the network device 102 may determine the number of SRS resources included in the SRS resource set based on the maximum number of SRS resources supported by the terminal, wherein the maximum number of SRS resources is less than or equal to the number of SRS resources included in the SRS resource set.

[0165] In some embodiments, the terminal 101 may report the maximum number of SRS resources supported by the terminal 101 to the network device 102 .

[0166] In some embodiments, the network device 102 may receive the maximum number of SRS resources supported by the terminal 101 as reported by the terminal 101 .

[0167] Step S2102 , the terminal 101 sends second information to the network device 102 .

[0168] In some embodiments, the second information is used to indicate first power information of an antenna port in the terminal.

[0169] In some embodiments, terms such as "first power information", "PA architecture", "rated power of each antenna port", "configurable power of each antenna port", "maximum power of each antenna port", and "capability information of each antenna port" can be used interchangeably.

[0170] In some embodiments, the network device 102 receives the second information sent by the terminal 101 .

[0171] In some embodiments, the first power information is used to indicate the rated power of each antenna port of the UE.

[0172] In some embodiments, the second information includes the first power information. For example, the second information includes [17, 17, 17, 17, 14, 14, 14, 14] dBm, or the second information includes [20, 20, 17, 17, 14, 14, 14, 14] dBm, and so on.

[0173] In some embodiments, the second information includes an indicator bit for implicitly indicating the first power information. For example, the value of the indicator bit corresponding to [17, 17, 17, 17, 14, 14, 14, 14]dBm is "001", the value of the indicator bit corresponding to [14, 14, 14, 14, 14, 14, 14, 14]dBm is "000", the value of the indicator bit corresponding to [17, 17, 17, 17, 17, 17, 17]dBm is "010", and so on. The present disclosure does not limit this.

[0174] In some embodiments, after receiving the second information, the network device 102 may determine the first power information of the antenna port in the terminal.

[0175] In some embodiments, the order of the above-mentioned step S2101 and step S2102 can be interchanged, or performed simultaneously, which is not limited in this disclosure.

[0176] Step S2103: The network device 102 determines a first SRS resource according to the first power information.

[0177] In some embodiments, the first SRS resource is used to assist the terminal in achieving maximum power uplink transmission. The first SRS resource is a subset of the SRS resource set, and the first SRS resource is an SRS resource in the SRS resource set.

[0178] In some embodiments, the first SRS resource is a single-port SRS resource, or the first SRS resource can also be a 2-port SRS resource, or the first SRS resource can also be a 4-port SRS resource, or the first SRS resource can also be an 8-port SRS resource, etc., which is not limited in this disclosure.

[0179] In some embodiments, the number of ports of the first SRS resource is related to the rated power of the antenna port indicated by the first power information.

[0180] In some embodiments, the first power information indicates that at least one antenna port can be configured to have a maximum power, and the first SRS resource is determined to be an SRS resource of an n-port.

[0181] For example, the first power information is PA = [23, 23, 17, 17, 14, 14, 14, 14] dBm. That is, there are two ports in the terminal that can be configured for maximum power (23 dBm). Therefore, the network device 102 can determine that the terminal 101 can use any port that can be configured for 23 dBm to achieve maximum power uplink transmission. Since the terminal 101 can achieve maximum power uplink transmission without port virtualization, the network device 102 can configure SRS resources of less than or equal to 8 ports for the terminal. At this time, the terminal 101 can use any port that can be configured for maximum power to achieve maximum power uplink transmission, for example, any of the two ports with PA = 23. At this time, the first SRS resource is an SRS resource for 8 ports. When the first SRS resource is an SRS resource with less than 8 ports, it is necessary to ensure that the antenna port corresponding to the physical antenna connected to the PA that supports full-power transmission is mapped to the SRS port, that is, the first SRS resource can be used to estimate the uplink channel corresponding to the physical antenna connected to the PA that supports full-power transmission; the first SRS resource can be used to estimate the uplink channel of the RF link corresponding to the PA that supports full-power transmission.

[0182] In some embodiments, the first power information indicates that there is no antenna port configurable to maximum power, and the sum of the powers of n antenna ports is equal to the maximum power, and the first SRS resource is determined to be a single-port SRS resource, where n is the number of antenna ports in the terminal.

[0183] For example, the first power information is PA = [14, 14, 14, 14, 14, 14, 14, 14] dBm. Since the total power of the 8 ports is 23 dBm, the network device 102 can determine that in order to achieve maximum power uplink transmission, the terminal 101 needs to virtualize the 8 ports into 1 virtual port, thereby determining that the first SRS resource is a single-port SRS resource.

[0184] In some embodiments, the first power information indicates that there is no antenna port that can be configured as the maximum power, and the sum of the powers of the n antenna ports is greater than the maximum power, and the first SRS resource is determined to be the SRS resource of L ports, where L is a positive integer less than n, and n is the number of antenna ports in the terminal.

[0185] For example, the first power information is PA = [17, 17, 17, 17, 14, 14, 14, 14] dBm. Since the sum of the powers of the eight ports is greater than 23 dBm, and the eight ports can be virtualized into four virtual ports with power information of [20, 20, 17, 17] dBm, or can be virtualized into two virtual ports with corresponding power information of [23, 20] dBm, the network device can determine that the first SRS resource can be a 2-port SRS resource or a 4-port SRS resource.

[0186] Step S2104 , the network device 102 sends first information to the terminal 101 .

[0187] In some embodiments, the first information is used to indicate a first SRS resource.

[0188] In some embodiments, the first information may be an SRS Resource Indicator (SRI).

[0189] In some embodiments, the SRS resource set includes X SRS resources, and the first information is The bit indicates the first SRS resource, where X is a positive integer, where Indicates rounding up to an integer.

[0190] In some embodiments, the SRS resource set includes four SRS resources, SRS#0, SRS#1, SRS#2, and SRS#3, and the first information uses 2 bits to indicate the first SRS resource.

[0191] For example, the first information is 00, which is used to indicate SRS#0, and the first information is 01, which is used to indicate SRS#1, and so on. This disclosure does not limit this.

[0192] In some embodiments, the SRS resource set includes 8 SRS resources, and the first information uses 3 bits to indicate the first SRS resource.

[0193] In some embodiments, the first resource may be a single-port SRS resource, or a 2-port SRS resource, or a 4-port SRS resource, or an 8-port SRS resource, etc., which is not limited in the present disclosure.

[0194] In some embodiments, the terminal 101 receives first information sent by the network device 102 .

[0195] In step S2105 , the terminal 101 virtualizes the antenna ports into a first number of virtual ports.

[0196] In some embodiments, the first number is the number of ports of the first SRS resource.

[0197] In some embodiments, the terminal 101 virtualizes the antenna port into a first number of virtual ports based on the first power information.

[0198] In some embodiments, the first power information indicates that at least one antenna port can be configured to have a maximum power, and an antenna port is determined to be a virtual port.

[0199] For example, the first power information is PA = [23, 23, 17, 17, 14, 14, 14, 14] dBm, that is, there are 2 ports in the terminal that can be configured to a maximum power of 23 dBm. At this time, the terminal 101 does not need to virtualize the antenna port into a virtual port to achieve maximum power transmission, so that the terminal 101 can determine that each antenna port is a virtual port.

[0200] In some embodiments, the first power information indicates that there is no antenna port that can be configured as the maximum power, and the sum of the powers of the n antenna ports is equal to the maximum power, and it is determined that the n antenna ports are virtualized into 1 virtual port, where n is the number of antenna ports in the terminal.

[0201] For example, the first power information is PA=[14, 14, 14, 14, 14, 14, 14, 14] dBm. Since the total power of the eight ports is 23 dBm, the terminal 101 needs to virtualize the eight ports into one virtual port to achieve maximum power uplink transmission.

[0202] In some embodiments, the first number is m, the first power information indicates that there is no antenna port that can be configured as maximum power, and the sum of the powers of the n antenna ports is greater than the maximum power, and at least two of the n antenna ports are determined to be virtualized into one virtual port, where n is the number of antenna ports in the terminal.

[0203] For example, if the first power information is PA = [17, 17, 17, 17, 14, 14, 14, 14] dBm, and the sum of the power of these eight ports is greater than 23 dBm, then two of the eight ports can be virtualized to obtain four virtual ports with second power information of [20, 20, 17, 17] dBm. In this case, the sum of the power of the two virtual ports equals the maximum power. Alternatively, four of the eight ports can be virtualized to obtain two virtual ports with second power information of [23, 20] dBm. In this case, one of the two virtual ports has power equal to the maximum power.

[0204] In some embodiments, at least one of the m virtual ports includes a virtual port corresponding to the maximum power, or the sum of the powers of at least two of the m virtual ports is equal to the maximum power. For example, when eight ports are virtualized into four virtual ports, the sum of the powers of two of the virtual ports is equal to the maximum power; when eight ports are virtualized into two virtual ports, the power of one of the virtual ports is equal to the maximum power.

[0205] In step S2106 , the network device 102 determines a first codeword according to the first power information.

[0206] In some embodiments, the number of ports indicated by the first codeword is the same as the number of ports of the first SRS resource.

[0207] In some embodiments, the terms "codeword", "precoding matrix", etc. can be used interchangeably.

[0208] In some embodiments, the first power information indicates that at least one antenna port can be configured for maximum power, and the first codeword is determined to be an n-port codeword including one non-zero port.

[0209] For example, the first power information is PA = [23, 23, 17, 17, 14, 14, 14, 14] dBm. That is, there are two ports in the terminal that can be configured to a maximum power of 23, so that the network device 102 can determine that the terminal can use any port that can be configured to 23 dBm to achieve maximum power uplink transmission, so the network device can determine the first codeword as [1, 0, 0, 0, 0, 0, 0]. T , or the first codeword is [-1,0,0,0,0,0,0,0] T , or the first codeword is [-j,0,0,0,0,0,0,0] T , or the first codeword is [j,0,0,0,0,0,0,0] T The present disclosure does not limit this. In this case, the terminal can use any port that can be configured to have the maximum power to achieve uplink transmission with the maximum power.

[0210] It should be noted that the first codewords in the above examples are all in the form of codewords when the transport layer (rank) is equal to 1. The network device can also determine the first codeword when the rank is not 1. For example, if rank = 3, the first codeword can be

[0211] In some embodiments, the first power information indicates that there is no antenna port that can be configured as maximum power, and the sum of the powers of n antenna ports is equal to the maximum power, and the first codeword is determined to be a single-port codeword containing a non-zero port, where n is the number of antenna ports in the terminal.

[0212] For example, the first power information is PA = [14, 14, 14, 14, 14, 14, 14] dBm. Since the power sum of the 8 ports is 23 dBm, the network device 102 can determine that the terminal achieves maximum power uplink transmission and needs to virtualize the 8 ports into 1 virtual port for use, so that the first codeword can be determined to be [1], or [-1], or [-j], or [j], etc., which is not limited in this disclosure, where j is

[0213] In some embodiments, the first power information indicates that there is no antenna port that can be configured as maximum power, and the sum of the powers of the n antenna ports is greater than the maximum power, and the second power information when the n antenna ports are virtualized into a first number of ports is determined, wherein the first number is the number of ports of the first SRS resource; the first codeword is determined based on the number of virtual ports indicated by the second power information and the configurable power of each virtual port.

[0214] For example, the first power information is PA = [17, 17, 17, 17, 14, 14, 14, 14] dBm. Since the sum of the powers of the eight ports is greater than 23 dBm, and the eight ports are virtualized into four virtual ports, the second power information is [20, 20, 17, 17] dBm. Alternatively, when two virtual ports are virtualized, the corresponding power information is [23, 20] dBm. Therefore, the network device can determine the first codeword based on the second power information.

[0215] In some embodiments, the second power information indicates that the configurable power of at least one of the virtual ports is the maximum power, and the first codeword is determined to be a non-coherent codeword of m ports, where m is the number of virtual ports indicated by the second power information.

[0216] For example, the second power information is PA = [23, 20] dBm, which means that the configurable power corresponding to one of the two virtual ports is the maximum power. Then the first codeword can be [1, 0]. T, or the first code word can also be Etc., the present disclosure does not limit this.

[0217] In some embodiments, the second power information indicates that there is no virtual port configured as maximum power, and the sum of the powers of the k virtual ports is equal to the maximum power, and the first codeword is determined to be a partially coherent codeword of m ports including k non-zero ports, where m is the number of virtual ports indicated by the second power information.

[0218] For example, the second power information is PA = [20, 20, 20, 17] dBm, which indicates 4 virtual ports, and the configurable power corresponding to each virtual port is less than the maximum power. Among them, the sum of the power of two virtual ports is equal to the maximum power. Then the first codeword can be [1, 0, 1, 0]. T . Or the first code word can also be The present disclosure does not limit this.

[0219] In some embodiments, after determining the first SRS resource, the network device 102 may determine the first codeword based on the determined first SRS resource.

[0220] Step S2107, the network device 102 sends a fourth message to the terminal 101.

[0221] In some embodiments, the fourth information is used to indicate the first codeword.

[0222] In some embodiments, the terminal 101 may receive fourth information sent by the network device 102 .

[0223] In some embodiments, the network device 102 may send the first information and the fourth information to the terminal 101 at the same time; alternatively, the network device 102 may first send the fourth information to the terminal 101 and then send the fourth information to the terminal 101. This disclosure does not limit this.

[0224] In some embodiments, terminal 101 may determine the first codeword by itself.

[0225] In some embodiments, the terminal 101 may determine the first codeword according to the second power information corresponding to the virtual port.

[0226] In some embodiments, the second power information indicates that at least one virtual port can be configured to a maximum power, and the terminal 101 may determine that the first codeword is a non-coherent codeword of an m-port, where m is a first number.

[0227] In some embodiments, the second power information indicates that there is no virtual port configured as maximum power, and the sum of the powers of the k virtual ports is equal to the maximum power. The terminal 101 can determine that the first codeword is an m-port codeword containing k non-zero ports, where m is the first number.

[0228] Among them, the specific implementation manner in which the above-mentioned terminal determines the first codeword based on the second power information can refer to the detailed description of some embodiments in the above-mentioned step S2106, which will not be repeated here.

[0229] In step S2108 , the terminal 101 performs uplink transmission using at least one virtual port based on the first codeword.

[0230] For example, the first SRS resource is a 4-port resource, and the second power information obtained after the terminal virtualizes the 8 ports is [20, 20, 17, 17] dBm. The first codeword indicated by the fourth information is [1, 0, 1, 0]. T , so that the terminal can perform uplink transmission to the network device 102 based on the first codeword, that is, using two virtual ports.

[0231] Alternatively, the first SRS resource is a 2-port resource, and the terminal virtualizes the 8 ports to obtain the second power information of [23, 20] dBm, and the first codeword is [1, 0] T , so that the terminal can use a virtual port to perform uplink transmission to the network device 102 based on the first codeword.

[0232] The information processing method involved in the embodiments of the present disclosure may include at least one of steps S2101 to S2108. For example, step S2101 may be implemented as an independent embodiment, step S2102 may be implemented as an independent embodiment, step S2103 may be implemented as an independent embodiment, and steps S2101+S2102 may be implemented as independent embodiments, but the present invention is not limited thereto.

For example, step S5101 may be implemented as an independent embodiment, step S5102 may be implemented as an independent embodiment, and steps S5101+S5102 may be implemented as independent embodiments, but are not limited thereto.

[0331] The steps in the embodiments of the present disclosure and their optional implementations may be arbitrarily combined with part or all of the steps in other embodiments, and may also be arbitrarily combined with the optional implementations of other embodiments.

[0332] The following is an exemplary introduction to the above method.

[0333] This disclosure mainly considers the SRS resource set configuration method and other related solutions when the uplink 8 ports transmit Mode 2 at full power.

[0334] The present disclosure proposes an SRS resource set configuration solution for uplink 8-port full-power transmission in Mode 2, so that the UE can achieve full-power transmission through SRS port virtualization.

[0335] The complete content of the disclosed technical solution is as follows:

[0336] When ULFPTxModes is configured as Mode 2, the UE can be configured with an SRS resource set, which contains one or more SRS resources with different numbers of SRS ports. The SRS resource set and SRS port virtualization are indicated by SRI, so that the UE can achieve full-power PUSCH transmission.

[0337] Option 1: The maximum number of SRS resources in the SRS resource set is 4, and a maximum of 2 bits of SRI indication is used

[0338] Option 2: The maximum number of SRS resources in the SRS resource set is 8, and a maximum of 3 bits of SRI indication is used.

[0339] The maximum number of SRS resources that can be supported according to UE capabilities is less than or equal to the maximum number of configurable SRS resources. For example, in Option 1, 2 or 4 SRS resources can be configured.

[0340] When configuring 2 SRS resources, each SRS resource can be configured with 1 or 2 ports, 1 or 4 ports, 1 or 8 ports, etc.

[0341] When 4 or 8 SRS resources are configured, each SRS resource can be configured with 1 or 2 ports, 1 or 4 ports, 1 or 8 ports, 1 or 2 or 4 ports, 1 or 2 or 8 ports, 1 or 4 or 8 ports, 1 or 2 or 4 or 8 ports, etc.

[0342] When there are multiple SRS resources with the same number of ports in the SRS resource set, each SRS resource can use a different spatial filter

[0343] When the number of SRS resource ports indicated by SRI is less than the number of antenna ports, the UE can achieve full-power transmission by merging the ports through SRS port virtualization; when the number of SRS resource ports indicated by SRI is equal to the number of antenna ports, the UE can achieve full-power transmission by reporting the TPMI group that allows full-power transmission.

[0344] Case 1: SRI indicates a single-port SRS resource (or 1-port SRS resource). The terminal virtualizes the SRS port and combines the 8 ports into 1 port, and transmits at full power through the single-port codeword. For example, for a terminal with PA = [14, 14, 14, 14, 14, 14, 14] dBm, the 8 ports are combined into 1 single port with 23 dBm, which can be transmitted through codeword 1.

[0345] Case 2: SRI indicates a 2-port SRS resource set. The terminal virtualizes the SRS port and combines the 8 ports into 2 ports. The R15 uplink 2-port codeword is used to transmit at full power. For example, for a terminal with PA = [17, 17, 17, 14, 14, 14] dBm, the 8 ports are combined into 2 ports [23, 20] dBm. The codeword [1 0] T transmission

[0346] Case 3: SRI indicates a 4-port SRS resource set. The terminal virtualizes the SRS ports and combines the 8 ports into 4 ports. The R15 uplink 4-port codeword is used to transmit at full power. For example, for a terminal with PA = [17, 17, 17, 14, 14, 14] dBm, the 8 ports are combined into 4 ports of [20, 20, 17, 17] dBm. The codeword [1, 0, 1, 0] can be used to transmit at full power. T transmission

[0347] Case 4: SRI indicates an 8-port SRS resource set. The terminal does not need to use port virtualization. The terminal can achieve full-power transmission by reporting the TPMI group that can support full-power transmission.

[0348] Potential Radio Resource Control (RRC) parameters

[0349] An RRC parameter, such as "ul-FullPwrMode2-MaxSRS-ResInSet-r18", is introduced to indicate the maximum number of SRS resources supported by the UE in each SRS resource set (usage set to 'codebook').

[0350] For example, the values ​​of ul-FullPwrMode2-MaxSRS-ResInSet-r18 are enumerated (ENUMERATED) as follows: {n1, n2, n4}, indicating that the maximum number of SRS resources supported by the UE in each SRS resource set is 1, 2, or 4.

[0351] Optional: ul-FullPwrMode2-MaxSRS-ResInSet-r18ENUMERATED{n1,n2,n4,n8}, indicating that the maximum number of SRS resources supported by the UE in each SRS resource set is 1, 2, 4, or 8.

[0352] An RRC parameter, such as "ul-FullPwrMode2-SRSConfig-diffNumSRSPorts-r18", is introduced to indicate the SRS configurations with different numbers of antenna ports per SRS resource set supported by the UE, where, for example, the value p1-2-4-8 indicates that each SRS resource set can be configured with 1, 2, 4, or 8 ports.

[0353] For example, the values ​​of ul-FullPwrMode2-SRSConfig-diffNumSRSPorts-r18 are enumerated as follows: {p1-2, p1-4, p1-8, p1-2-4, p1-2-8, p1-4-8, p1-2-4-8}.
