A communication device, comprising a processor, a memory, and a program or instructions stored in the memory and capable of running on the processor, wherein the program or the instructions, when executed by the processor, causes the communication device to perform:
- obtaining wake-up signal configuration information;
- performing detection for a wake-up signal within a first duration according to the wake-up signal configuration information, wherein the first duration belongs to a physical downlink control channel (PDCCH) monitoring period configured by a network-side device;
- and
- determining a monitoring behavior for a target channel based on the detection of the wake-up signal, wherein the target channel comprises at least one of the following:
- physical downlink control channel (PDCCH);
- physical downlink shared channel (PDSCH);
- and
- physical uplink shared channel (PUSCH).
