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 discloses a sounding reference signal transmission method and a communication apparatus. In the method, a network device sends configuration information of one or more sounding reference signal (SRS) ports to a terminal device, where the configuration information indicates a sending occasion corresponding to the SRS port, each SRS port is in one-to-one correspondence with a receive antenna of the terminal device, and SRS transmit bandwidths corresponding to at least two of sending occasions corresponding to each SRS port are different; and the terminal device sends an SRS based on the SRS resource configuration information.
