Abstract: Embodiments of this application disclose a communication method and an apparatus, and relate to the communication field, to support a terminal device in performing beam failure detection in a common beam scenario. The method includes: A terminal device receives a first transmission configuration indicator (TCI) from an access network device, where the TCI may indicate a common beam. For example, the first TCI includes information about a first uplink reference signal and/or information about a first downlink reference signal, a spatial transmission filter corresponding to the first uplink reference signal is used for sending a plurality of uplink channels, and the first downlink reference signal and demodulation reference signals DMRSs of a plurality of downlink channels meet a quasi co-location QCL relationship.

Abstract: A method includes configuring, by a terminal, spatial reception parameters of K channel resources as spatial reception parameters of each interference resource of M interference resources of the terminal, wherein the K channel resources are channel resources on which the terminal is configured to simultaneously receive signals from a network device, and M is a positive integer. The method further includes determining, by the terminal, a first measurement result of the K channel resources based on spatial reception parameters of a first interference resource in the M interference resources, wherein K is a positive integer greater than or equal to 2. The method further includes sending, by the terminal, a measurement report to the network device, wherein the measurement report indicates M measurement results, and the measurement report includes the first measurement result.
