Abstract
One example method includes receiving first indication information through a higher layer signaling, the first indication information indicating an available codebook subset, receiving downlink control information, determining a precoding matrix corresponding to a transmission precoding matrix indicator (TPMI) and a transmission rank obtained from the downlink control information, where the precoding matrix belongs to the available codebook subset indicated by the first indication information, precoding a signal based on the determined precoding matrix, and sending the precoded signal to a network device.
