1. A precoding matrix configuration method, applied to uplink transmission, comprising:
generating first configuration information to configure M precoding matrices, wherein M is an integer that is equal to or bigger than 2; and
transmitting, to a terminal device, the first configuration information;
wherein:
in response to the uplink transmission is non-codebook-based uplink transmission, the first configuration information comprises first indication information indicating M sounding reference signal resource indicators (SRIs), and wherein the M SRIs are used to configure the M precoding matrices;
in response to the uplink transmission is codebook-based uplink transmission, the first configuration information comprises second indication information indicating M transmit precoding matrix indicators (TPMIs), and wherein the M TPMIs are used to configure the M precoding matrices.
