Reference resource or capability for cross-link interference measurement
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a cross-link interference (CLI) measurement reporting configuration indicating a reporting resource for reporting of a CLI measurement regarding an aggressor network node or an aggressor UE associated with the aggressor network node. The UE may transmit a CLI measurement report on the reporting resource, the CLI measurement report indicating the CLI measurement on a measurement resource that occurs no later than a CLI reference resource that is defined by an offset relative to the reporting resource. Numerous other aspects are described.
