A communication method, comprising: monitoring, by a terminal device, a wake-up signal from a network device, wherein the wake-up signal is used to wake up the terminal device that monitors, on a next paging occasion, PO, a physical downlink control channel, PDCCH, scrambled by a paging radio network temporary identifier, P-RNTI; determining (S202, S304, S404, S504), according to the wake-up signal, by the terminal device, a monitoring situation of monitoring on the next PO the PDCCH scrambled by the P-RNTI; wherein the wake-up signal is used for an indication of at least one group of terminal devices of multiple groups of terminal devices monitoring on the next PO the PDCCH scrambled by the P-RNTI; wherein the wake-up signal comprises first indication information, the first indication information is used for an indication of waking up at least one group of terminal devices; characterized in that the first indication information is bitmap information, each bit in the bitmap information corresponds to a group of terminal devices, and the bit is used for an indication of waking up a wake-up state of the terminal device in the corresponding group of terminal devices; wherein the monitoring, by the terminal device, the wake-up signal from the network device comprises: monitoring, by the terminal device, the wake-up signal from the network device on a monitoring occasion of a target time period; wherein the target time period is a time period between a maximum time offset of the next PO and a minimum time offset of the next PO. monitoring, by a terminal device, a wake-up signal from a network device, wherein the wake-up signal is used to wake up the terminal device that monitors, on a next paging occasion, PO, a physical downlink control channel, PDCCH, scrambled by a paging radio network temporary identifier, P-RNTI; determining (S202, S304, S404, S504), according to the wake-up signal, by the terminal device, a monitoring situation of monitoring on the next PO the PDCCH scrambled by the P-RNTI; wherein the wake-up signal is used for an indication of at least one group of terminal devices of multiple groups of terminal devices monitoring on the next PO the PDCCH scrambled by the P-RNTI; wherein the wake-up signal comprises first indication information, the first indication information is used for an indication of waking up at least one group of terminal devices; characterized in that the first indication information is bitmap information, each bit in the bitmap information corresponds to a group of terminal devices, and the bit is used for an indication of waking up a wake-up state of the terminal device in the corresponding group of terminal devices; wherein the monitoring, by the terminal device, the wake-up signal from the network device comprises: monitoring, by the terminal device, the wake-up signal from the network device on a monitoring occasion of a target time period; wherein the target time period is a time period between a maximum time offset of the next PO and a minimum time offset of the next PO. monitoring, by the terminal device, the wake-up signal from the network device on a monitoring occasion of a target time period; wherein the target time period is a time period between a maximum time offset of the next PO and a minimum time offset of the next PO.
