Abstract

The present disclosure relates to resource indication methods and apparatus. In one example method, a network device configures resource configuration information for a terminal device. The terminal device determines channel state information based on the resource configuration information, and sends the channel state information. The resource configuration information is used to indicate a first reference signal resource set, L second reference signal resource sets, and a type of the first reference signal resource set. The first reference signal resource set includes resources for M first reference signals, and a resource for one of the M first reference signals is used to measure a channel.
