A communication method, a communication apparatus, and a storage medium, where the method includes: configuring, for a terminal device, a sounding reference signal (SRS) resource whose port quantity corresponds to an antenna sending capability of the terminal device, where the antenna sending capability of the terminal device indicates a maximum quantity of antennas capable of being simultaneously used by the terminal device to send a signal; receiving SRSs from the terminal device, where the terminal device includes at least two sub-receivers, and the SRSs are sent by the terminal device separately through antennas of different sub-receivers based on the SRS resource; and determining, based on the port quantity of the SRS resource and an antenna quantity of each sub-receiver of the terminal device, a sub-receiver corresponding to a port corresponding to the SRS.
