Abstract: A communication method and a communication apparatus. The method includes: A terminal device sends an uplink reference signal to an access network device based on a sending pattern, where an uplink reference signal resource of the uplink reference signal includes N ports, the N ports in the sending pattern are carried on two or more OFDM symbols, or the N ports in the sending pattern are carried on two or more frequency domain combs and one OFDM symbol, and N is an integer greater than 4; and the terminal device receives precoding indication information indicating precoding for transmitting uplink data, the precoding indication information is obtained by the access network device based on the uplink reference signal, and rows of a matrix corresponding to the precoding are in one-to-one correspondence with the N ports.

Abstract: This application provides channel state information reporting methods and communications apparatuses. One method includes: generating first indication information and a plurality of groups of second indication information, where the first indication information indicates a plurality of frequency domain component vectors, each group in the plurality of groups of second indication information corresponds to a spatial layer and a plurality of spatial domain component vectors and constructs precoding vectors of the spatial layer in a plurality of frequency bands, and each piece of second indication information in each group corresponds to a spatial domain component vector in the plurality of spatial domain component vectors and indicates at least one of the plurality of frequency domain component vectors that corresponds to the spatial domain component vector; and sending the first indication information and the second indication information.
