Abstract: This application provides a rate matching method and an apparatus. The method includes: A terminal device measures a reference signal delivered by a serving network device; the terminal device reports a measurement result to the serving network device; and if the measurement result indicates that quality of the reference signal is less than or equal to a first threshold, the terminal device performs rate matching on a transmission resource of a serving cell based on a location of a reference signal resource of a neighboring cell. This method reduces unnecessary rate matching in neighboring cell measurement, enhances rate matching reliability, and improves transmission efficiency.

Abstract: In a guard symbol configuration method and a communication apparatus, a first node indicates, to a second node, a number of guard symbols used or expected to be used in a larger subcarrier spacing, to avoid a scheduling conflict. The method includes: the first node sends a first medium access control control element (MAC CE) to the second node, where the first MAC CE indicates a number of guard symbols used in a first subcarrier spacing. The first node sends a second MAC CE to the second node, where the first MAC CE and the second MAC CE are jointly used to determine a number of guard symbols used or expected to be used in a second subcarrier spacing.
