1. A method, comprising:
at a base station:
transmitting a message to a user equipment (UE) comprising a group ID, wherein the group ID is assigned to a group of UEs by a network and indicated via non-access stratum (NAS) signaling;
transmitting one or more synchronization signals, wherein the synchronization signals correspond to a wake-up signal (WUS) that is to be transmitted to the UE when the UE is operating in a paging discontinuous reception (DRX) cycle that includes a paging occasion (PO); and
transmitting the WUS to at least the UE during a WUS occasion, wherein the WUS indicates that the UE is to utilize an active mode during the PO when the WUS includes the group ID and the UE is to utilize a sleep mode during the PO when the WUS does not include the group ID.
