Abstract:
Systems and methods of increasing paging opportunities when the unlicensed band is used are described. The gNB sends an RRC message that indicates multiple monitoring occasions in a paging occasion of a paging frame. The UE monitors a monitoring occasion of a PO to determine whether a PDCCH with a P-RNTI has been received in an unlicensed band. If such a PDCCH is received, the UE decodes PDSCH information in the PDCCH to determine whether the P-RNTI is a P-RNTI of the UE. If so, the UE avoids monitoring subsequent monitoring occasions of the PO. If the PDCCH does not contain a P-RNTI, the UE continues to monitor other monitoring occasions within the PO.
