In the study of MIMO uplink 8-port transmission enhancement of R18, relevant discussions were conducted on the design of fully coherent codebooks, partially coherent codebooks, incoherent codebooks, TPMI design, and full-power transmission. Optionally, the number of antenna port groups of the user equipment (UE) is defined as Ng, and the antennas in each antenna port group are fully coherently transmitted, and the antennas between different antenna port groups are incoherently transmitted. When the UE is a fully coherent UE, Ng=1; when the UE is a partially coherent UE, Ng=2 or 4; when the UE is an incoherent UE, Ng=8. For the 8-port fully coherent codebook, the 8-port R15 downlink Type I codebook is used, and the oversampling coefficient is set to 1. For the partially coherent codebook with Ng=2, the design is based on the R15 uplink 4-port codebook. For the partially coherent codebook with Ng=4, the design is based on the R15 uplink 2-port codebook. For the incoherent codebook, all antenna selection vectors or antenna selection matrices are used. For some 8-port codewords, due to the limitation of power control rules, full power transmission cannot be achieved. The transmission power needs to be multiplied by the power scaling factor, which is defined as the number of antenna ports for non-zero PUSCH transmission divided by the total number of configured antenna ports. For example, when the 4-port codeword is When the 4-port codeword is When , the parameter is 4 / 4 = 1, then Therefore, when the number of uplink transmission ports is 8, the fully coherent codebook can achieve full power transmission, the partially coherent codebook with Ng=2 cannot achieve full power transmission when the number of layers is 1, the partially coherent codebook with Ng=4 cannot achieve full power transmission when the number of layers is 1 to 3, and the incoherent codebook cannot achieve full power transmission when the number of layers is 1 to 7. In the discussion of R16 uplink 2-port and 4-port full power transmission, multiple full power transmission modes are defined to achieve full power transmission. First, according to the different power amplifier (PA) architectures of the terminal, for terminals of power class 3, the full power, maximum power or rated power (full rated) of the amplifier is 23dBm, so three different UE capabilities are defined. The following takes a 2-port terminal as an example. UE capability 1: The RF chain corresponding to each port is configured with a PA capable of full power, for example, [23 23] dBm. UE capability 2: The RF chain corresponding to each port is not configured with a PA that can provide full power, for example, [20 20] dBm. UE capability 3: The RF chains corresponding to some ports can be configured with full-power PAs, for example, [23 20]dBm. In view of the above three UE capabilities, R16 proposes three full-power transmission modes, namely Mode 0, Mode 1 and Mode 2 below. Mode 0: In Mode 0, the 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 Full power is transmitted through the first PA alone. 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. Mode 2: In Mode 2, full-power transmission can be achieved through two methods. In method 1, full-power transmission of a single port can be achieved through port virtualization. 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 PA = [20 20 1717] dBm (i.e., the first port, the second port, the third port, and the fourth port correspond to 20, 20, 17, and 17 dBm, respectively), the base station configures 2-port SRS resources, and the terminal can obtain [23 20] dBm through SRS port virtualization, i.e., the first two ports are virtualized into one port, at which time, two 20 dBm can be virtualized to obtain 23 dBm, and the third and fourth ports are virtualized into one port, at which time, two 17 dBm can be virtualized to obtain 20 dBm. In this way, the codeword is used. Full power transmission can be achieved. In method 2, the terminal reports the TPMI group that can support full power transmission according to the PA architecture. For example, for PA = [20 20 20 17] dBm, TPMI group G3 can be reported. The following table is a schematic table of TPMI group G3, where TPMI group G3 can enable the terminal to achieve full power transmission under PA = [20 20 20 17] dBm. FIG2 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2, the present disclosure embodiment relates to a communication method, which is used in a communication system 100. The communication system 100 may include a terminal 101 and a network device 102. The method includes: Step 2101: The terminal determines the first information. In some embodiments, the terminal may determine the first information based on a power amplifier PA structure of the terminal. In some embodiments, the name of the first information is not limited, and it can be "index information", "indication information" and the like. In some embodiments, the indication method of the first information is not limited, and it can be indicated by an index value (index) of several bits, or by a bitmap (bitmap). In some embodiments, the first information is used to indicate at least one antenna port group of the terminal and the transmission precoding matrix corresponding to at least one antenna port group indicates a TPMI group, the TPMI group includes at least two transmission layers and at least two TPMIs, and the activated antenna ports corresponding to at least two TPMIs are included in at least one antenna port group, and at least one antenna port group and TPMI group are used to enable the terminal to transmit at full power. Uplink channel and / or uplink signal. In some embodiments, the TPMI group may include at least a first TPMI and a second TPMI, wherein the number of transmission layers of the first TPMI is different from the number of transmission layers of the second TPMI. The number of transmission layers has a corresponding relationship with the TPMI. For example, the index of the first TPMI is 0-15, and its corresponding precoding matrix is The number of transmission layers is 1; the index of the second TPMI is 0–7, and its corresponding precoding matrix is The number of transmission layers is 2. In some embodiments, the terminal may determine different first information for different PA architectures. For example, when the PA architecture of the terminal is that all port groups can achieve full power transmission, the first information may indicate any antenna port group to transmit. For example, when PA=

[2323] dBm, the first information may indicate that the first antenna port group or the second antenna port group has full-power transmission capability; when the PA architecture is that some port groups can achieve full-power transmission, the full-power port group can be specified for transmission, for example, when PA=[23 20 20 17]dBm, the first information may indicate that the first antenna port group has full-power transmission capability; when PA=[23 20 23 17]dBm, the first information may indicate that the first antenna port group has full-power transmission capability; when the PA architecture is that some port groups can achieve full-power transmission, the combination of antenna port groups may also be indicated to have full-power transmission capability, for example, when PA=[23 20 20 17]dBm, the first information may indicate that the combination of the second antenna port group and the third antenna port group has full-power transmission capability; when the PA architecture is that any port group alone cannot achieve full-power transmission, but a combination of multiple port groups can achieve full-power transmission, the first information may indicate that a combination of multiple antenna port groups has full-power transmission capability, for example, when PA=[17 20 20 17]dBm, the first information may indicate that the combination of the second antenna port group and the third antenna port group has full power transmission capability. In some embodiments, the number of antenna ports of the terminal may be 4, 8, 16, etc., which is not limited in the present disclosure. In the case where the terminal has 8 antenna ports, for different types of terminals, the following discusses the manner of determining the first information according to the PA of the terminal.
