Briefly, in accordance with one or more embodiments, an apparatus of user equipment (UE), comprises one or more baseband processors to derive a dynamic scrambling key, and a memory to store the dynamic scrambling key and a temporary UE identifier (temporary UE ID) assigned to the UE. The one or more baseband processors monitor a paging request for a scrambled UE identifier (UE ID) to determine ifthe paging request is intended for the UE by unscrambling the scrambled UE ID with the dynamic scrambling key to produce the temporary UE ID. The paging request is intended for the UE if the temporaryUE ID produced by unscrambling the scrambled UE ID matches the temporary UE ID stored in the memory. A new dynamic scrambling key may be derived each time the UE returns to a radio resource control idle (RRC_IDLE) state.
