Abstract: This application provides a method which includes: receiving, by a terminal, N reference signal groups, where each of the N reference signal groups includes at least two reference signals that are simultaneously received; and sending indication information used to indicate channel state information of at least one reference signal in each of K reference signal groups. Therefore, the terminal can feed back the channel state information of the reference signal in a scenario in which a plurality of reference signals can be simultaneously received, so that a network device selects a beam from a plurality of beams that can be simultaneously sent to send data.

Abstract: A communication method and a communications apparatus are provided. The method includes: determining a first bandwidth part (BWP) and a second BWP; determining an association relationship between the first BWP and the second BWP; and recovering a link of a first downlink resource of the first BWP based on the association relationship and/or detecting a link failure of a second downlink resource of the second BWP based on the association relationship. The link of the first downlink resource of the first BWP can be accurately recovered based on the association relationship between the two BWPs, thereby ensuring communication reliability.

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.
