1. An interference rejection combining method, wherein the method comprises:
receiving, by a terminal device, one or more signals on a first resource, wherein the first resource includes N first resource units, a zero power (ZP) resource, and M second resource units, the N first resource units includes a first resource unit carrying a first demodulation reference signal DMRS, the M second resource units includes a second resource unit carrying first data, and N and M are positive integers;
performing, by the terminal device, interference and noise measurement on a physical downlink shared channel (PDSCH) based on a first signal of the one or more signals received on the N first resource units and a second signal of the one or more signals received on the ZP resource, to obtain an interference and noise measurement result, wherein the interference and noise measurement result indicates a first covariance matrix of interference and noise of the PDSCH; and
demodulating, by the terminal device based on the interference and noise measurement result, a third signal of the one or more signals received on the M second resource units, to obtain the first data.
