For example, before S202, the terminal may receive downlink control information (Downlink Control Information, DCI), and the DCI may be used to indicate the two first precoding matrices.
上述两个第一预编码矩阵中,一个可以是支持M端口PUSCH传输的预编码矩阵,另一个可以是支持N端口PUSCH传输的预编码矩阵,M+N=K,M和N是正整数。例如,K的取值可以为6或8等,在K为6时,M和N的取值可以分别为2和4;又例如,在K为8时,M和N的取值可以均为4。Of the two first precoding matrices, one may be a precoding matrix supporting M-port PUSCH transmission, and the other may be a precoding matrix supporting N-port PUSCH transmission, where M+N=K, and M and N are positive integers. For example, the value of K may be 6 or 8, and when K is 6, the values of M and N may be 2 and 4, respectively; for another example, when K is 8, the values of M and N may both be 4.
第一预编码矩阵可以是相关技术中网络侧设备为终端配置的预编码矩阵,例如,第一预编码矩阵可以为支持4端口PUSCH传输的预编码矩阵,如The first precoding matrix may be a precoding matrix configured by a network side device for a terminal in the related art.

又例如,第一预编码矩阵可以为支持2端口PUSCH传输的预编码矩阵,如For another example, the first precoding matrix may be a precoding matrix supporting 2-port PUSCH transmission, such as
等。 wait.
在一个例子中,终端确定出的第二预编码矩阵可以为如下之一:In an example, the second precoding matrix determined by the terminal may be one of the following:
其中,W1和W2为第一预编码矩阵,和α为系数,该系数可以是相位、幅度或系数矩阵,如[1j]T等。Wherein, W1 and W2 are the first precoding matrices, and α are coefficients, which can be phase, amplitude or coefficient matrix, such as [1j] T , etc.

本申请实施例提供的PUSCH传输方法,终端可以根据两个第一预编码矩阵确定出一个第二预编码矩阵,根据第二预编码矩阵进行K端口的PUSCH传输。本申请实施例可以使用两个支持较少端口PUSCH传输的预编码矩阵,来实现多端口的PUSCH传输,有利于提高终端的通信性能。In the PUSCH transmission method provided in the embodiment of the present application, the terminal can determine a second precoding matrix according to the two first precoding matrices, and perform K-port PUSCH transmission according to the second precoding matrix.

同时,本申请实施例无需重新配置预编码矩阵,对现有的协议改动较小,例如,不需要引入新的8Tx(传输)预编码矩阵就能实现8Tx传输,终端实现简单,且有利于较少资源开销。At the same time, the embodiments of the present application do not need to reconfigure the precoding matrix, and the changes to the existing protocol are relatively small. For example, 8Tx transmission can be achieved without introducing a new 8Tx (transmission) precoding matrix. The terminal implementation is simple and conducive to less resource overhead.
