Wake-up signal (WUS) design and configuration for paging

A method, performed by a user equipment (UE), of wake-up signal (WUS) detection for facilitating paging in a wireless communication system, the method comprising:

• receiving from a next generation Node B (gNB) configuration information indicating a secondary synchronization signal (SSS)-like sequence corresponding to a paging occasion in a paging frame;
• detecting presence of a WUS in a SSS corresponding to the paging occasion;
• and
• attempting to decode the SSS-like sequence of the WUS received via resources of the SSS to determine whether the paging occasion includes a paging message for the UE.

A method, performed by a user equipment (UE), of wake-up signal (WUS) detection for facilitating paging in a wireless communication system, the method comprising:

• detecting a Synchronization Signal Block (SSB) for time and frequency tracking;
• searching for a WUS in downlink control information (DCI) corresponding to a paging occasion in a paging frame, the DCI including subgrouping information;
• in response to detecting the WUS, checking the subgrouping information;
• and
• in response to the subgrouping information applying to the UE, attempting to decode a paging message at the paging occasion.
