1. A communication method, comprising:
receiving monitoring information from a network device, wherein the monitoring information comprises information of a search space set corresponding to a wake-up signal (WUS), wherein the information of the search space set identifies one or more search space sets to be activated, wherein each of the one or more search space sets includes a monitoring periodicity and an intra-slot monitoring start symbol;
determining at least one of a monitoring periodicity of the WUS or a monitoring occasion in the monitoring periodicity based on the information of the search space set;
receiving the WUS from the network device, wherein the WUS comprises wake-up information of at least one terminal device, and wherein the WUS comprises a first index indicating scheduling information of an aperiodic channel state information reference signal (A-CSI-RS), a go-to-sleep (GTS) duration, and a second index indicating a GTS pattern; and
performing, based on wake-up information of a terminal device, physical downlink control channel (PDCCH) monitoring in an on duration of at least one discontinuous reception (DRX) cycle corresponding to the WUS, wherein the wake-up information of at least one terminal device comprises the wake-up information of the terminal device.
