Abstract: This application provides a resource measurement method and an apparatus. A terminal receives measurement configuration information including N resource sets, and determines, based on a value of N, to send a first measurement result or a second measurement result to a network device. Specifically, the terminal sends the first measurement result to the network device when N>1, where the first measurement result is used to indicate m resources, downlink signals corresponding to the m resources can be simultaneously received by the terminal, and the m resources are in a one-to-one correspondence with m resource sets in the N resource sets. The terminal sends the second measurement result to the network device when N=1.
