1. A method, wherein the method comprises:
sending, by a network device, first signaling, wherein the first signaling carries first indication information, the first indication information indicates a subset identifier corresponding to a first precoding subset in a first codebook, the first codebook comprises a plurality of precoding subsets, each precoding subset comprises a plurality of precoding matrices, and different precoding subsets correspond to different subset identifiers; and
sending, by the network device, second signaling, wherein the second signaling carries second indication information, the second indication information indicates a matrix identifier corresponding to a first precoding matrix in the first precoding subset, different precoding matrices in the first precoding subset correspond to different matrix identifiers, and the first precoding matrix is used to precode a physical uplink shared channel (PUSCH) carried on a first subband.
