Abstract: This application discloses a reference signal configuration method and apparatus. Before a network device sends reference signals aperiodically, the network device sends configuration information to a terminal device, where the configuration information is used to indicate a timeslot offset of one or more reference signal resource sets. Therefore, the network device can flexibly send reference signals in different timeslots, thereby reducing a quantity of times of reference signal triggering and measurement result reporting, and improving efficiency of a communications system.

Abstract: The present disclosure relates to resource configuration methods and apparatus. A user equipment (UE) generates receiving beam quantity indication information indicating a maximum quantity of receiving beams that is supported by the UE, and sends the receiving beam quantity indication information to a network device. The maximum quantity of receiving beams is used for a configuration of a beam management reference signal resource for the UE. The UE receives the configuration of a beam management reference signal resource for the UE from the network device.
