Abstract
Embodiments of this application relate to the field of communications technologies, and disclose a precoding matrix configuration method and apparatus, to help improve performance of decoding data. The method, applied to uplink communication, includes generating first configuration information to configure M precoding matrices, where M is an integer that is equal to or bigger than 2. The method further includes transmitting, to a terminal device, the first configuration information. 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 where 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 where the M TPMIs are used to configure the M precoding matrices.
