[0207] For uplink 8-port transmission enhancement, the design of fully coherent codebook, partially coherent codebook, non-coherent codebook equipment, TPMI design, and full-power transmission design are proposed.

[0208] The number of antenna port groups of the terminal is Ng, and the antennas in each antenna port group are fully coherently transmitted, and the antennas between different antenna port groups are incoherently transmitted.

[0209] When the terminal is a fully coherent terminal, Ng = 1; when the terminal is a partially coherent terminal, Ng = 2 or 4; when the terminal is an incoherent terminal, Ng = 8. For the 8-port fully coherent codebook, the 8-port R15 downlink Type I codebook is used, and the oversampling factor 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 with Ng = 8, all antenna selection vectors or antenna selection matrices are used.

[0210] It is understandable that for some 8-port codewords, full-power transmission cannot be achieved due to the limitations of PUSCH power control rules.

[0211] Among them, in the power control rule of PUSCH, its 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, which means full power transmission can be achieved.

[0212] Therefore, when the number of uplink transmission ports is 8, the 8-port fully coherent codebook can achieve full-power transmission. When the number of layers of the 8-port partially coherent codebook with Ng=2 is 1, full-power transmission cannot be achieved. When the number of layers of the 8-port partially coherent codebook with Ng=4 is 1 to 3, full-power transmission cannot be achieved. When the number of layers of the 8-port incoherent codebook with Ng=8 is 1 to 7, full-power transmission cannot be achieved.

[0213] In the discussion of full-power transmission of uplink 2 ports and 4 ports, in order to achieve full-power transmission, multiple full-power transmission modes are defined. According to the different power amplifier (PA) architectures of the terminal, three different capabilities are defined for power class 3.

[0214] Among them, Capability 1: Each RF chain is configured with a PA capable of full power, for example, [23 23]dBm; Capability 2: Each RF chain is not configured with a PA capable of full power, for example, [20 20]dBm; Capability 3: Some RF chains are configured with PAs capable of full power, for example, [23 20]dBm.

[0215] For the three different capabilities of the terminal, three full-power transmission modes are proposed. Mode 0: The physical uplink shared channel (PUSCH) power scaling factor is fixed to 1, corresponding to the terminal 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 transmission can be achieved through only the first PA. Mode 1: Corresponding to capabilities 2 and 3 of the terminal, 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: Corresponding to capabilities 2 and 3 of the terminal, full power transmission is achieved through two methods. In method 1, the terminal achieves full power transmission by virtualizing the sounding reference signal (SRS) port. For example, for [20 20 17 17]dBm, the base station configures 2 ports of SRS, and the UE can obtain [23 20]dBm through SRS port virtualization, that is, using codeword to achieve full-power transmission; in method 2, the terminal reports a transmission precoding matrix indicator (TPMI) group that can support full-power transmission according to the PA architecture. For example, for [20 20 20 17]dBm, TPMI group G3 can be reported.

[0216] Illustratively, the codewords included in the TPMI group G3 are as described in Table 1 below.

[0217] Table 1

[0218] In some embodiments, for a non-coherent codebook with 2 antenna ports, to achieve uplink full power transmission:

[0219] When the number of transmission layers is 1, the codeword corresponding to TPMI=2 is added.

[0220] In some embodiments, for a non-coherent codebook with 4 antenna ports, to achieve uplink full power transmission:

[0221] When the number of transmission layers is 1, for both CP-OFDM and DFT-s-OFDM waveforms, add the codeword corresponding to TPMI=13.

[0222] When the number of transmission layers is 2, add the codeword corresponding to TPMI=6;

[0223] When the number of transmission layers is 3, the codeword corresponding to TPMI=1 is added.

[0224] In some embodiments, for a partially coherent codebook with 4 antenna ports, to achieve uplink full power transmission:

[0225] When the number of transmission layers is 1, codewords corresponding to TPMI=12-15 are added for both CP-OFDM waveform and DFT-S-OFDM waveform.

[0226] In the related art, a terminal supporting 8-port non-coherent transmission with at least one of the transmission layers 1 to 7 does not support full-power transmission when using an 8-port non-coherent codebook with any of the transmission layers 1 to 7 to transmit uplink signals or uplink channels. This is an urgent problem that needs to be solved.

[0227] Based on this, embodiments of the present disclosure provide a codebook indication method, terminal, and network device. The method, performed by the terminal, includes receiving indication information sent by the network device, wherein the indication information is used to indicate a codebook configured by the network device for the terminal, indicating that the terminal supports 8-port non-coherent transmission with at least one transmission layer number from 1 to 7, and at least one codeword in the codebook supports full-power uplink transmission of the terminal. This enables full-power uplink transmission of the terminal, increases the terminal's transmit power, and improves uplink transmission performance.
