Abstract
Wireless communications systems and methods related to performing paging operations in a shared radio frequency band (e.g., in a shared spectrum or an unlicensed spectrum) with an improved paging reliability. A first user equipment (UE) determines a frequency hopping pattern for a paging occasion window (POW) in a plurality of frequency subbands within a shared radio frequency band. The first UE monitors for a paging message from a base station (BS) in the POW, where the monitoring includes hopping from at least a first frequency subband of the plurality of frequency subbands to a second frequency subband of the plurality of frequency subbands based on the frequency hopping pattern.
Claims28
