Filed on 30 October 2024
Abstract
The present application provides a codebook-based uplink channel sending method and an apparatus, and relates to the technical field of communications. The method comprises: determining a codebook set matching the number of antenna ports of a terminal device for sending an uplink channel, the maximum number of antenna ports of the uplink channel being 8 (201); receiving indication information sent by a network device (202); according to the indication information, determining a corresponding precoding matrix from the codebook set (203); precoding the uplink channel by using the precoding matrix (204); and sending the precoded uplink data channel to the corresponding network device (205). Codebook-based uplink transmission may realize spatial multiplexing, thus effectively increasing the uplink channel transmission rate, and improving communication efficiency.
