Abstract: Example communication methods and communications apparatus to measure an interference degree in a cross-link interference scenario are described. One example method includes receiving at least one first sounding reference signal (SRS) by a first terminal from at least one second terminal. The first terminal obtains, based on the at least one first SRS, information about one or more measurement results of the at least one second terminal, and sends information about the one or more measurement results to a network device. The one or more measurement results indicate signal strength of the at least one first SRS from the second terminal, the first SRS is used to measure cross-link interference (CLI), and the first SRS occupies a first resource.
