Method, user equipment, base station, and readable storage medium for transmitting wake-up signal

A user equipment (UE) for monitoring a wake-up signal (WUS), the UE comprising:

• a transceiver;
• and
• a processor configured to:
• control the transceiver to receive first information on a UE group WUS and second information on a common WUS in a system information block (SIB),
• determine a first paging cycle and the UE group WUS corresponding to a UE group to which the UE belongs among a plurality of UE groups based on the first information,
• determine a maximum duration for monitoring the UE group WUS based on a value corresponding to a ratio configured in the first information,
• determine a second paging cycle based on a monitoring cycle of the common WUS included in the second information and a third paging cycle of paging occasion (PO),
• monitor the common WUS which is used to wake up all UEs monitoring a same WUS resource based on the second paging cycle,
• in response to the common WUS being detected, monitor at least one first PO based on the third paging cycle,
• in response to the common WUS not being detected, monitor the UE group WUS based on the maximum duration and the first paging cycle, and
• in response to the UE group WUS being detected, monitoring at least one second PO based on the third paging cycle.
