Abstract
A terminal device may receive precoding indicator information, where the precoding indicator information includes K first indicators and one second indicator. The terminal device determines K first precoding matrices based on the K first indicators, and determines a second precoding matrix based on the second indicator, where K is a positive integer. The terminal device precodes, by using the K first precoding matrices, data sent in K first frequency bands, to obtain precoded first data, and precodes, by using the second precoding matrix, data sent in a second frequency band, to obtain precoded second data. The K first frequency bands are located in some frequency bands in a physical uplink shared channel (PUSCH) scheduling frequency band. The second frequency band is a frequency band in the PUSCH scheduling frequency band other than the K first frequency bands.
