Beam-related paging assistance information can be exchanged between a core network, radio access networks, and user equipment. Beam-related paging assistance information can enable more efficient paging operations at a base station. A centralized unit (CU) of a base station can exchange beam-related paging assistance information with a distributed unit (DU) of the base station to facilitate paging operations using the beam-related paging assistance information.

A method of handling Paging Early Indication with Paging Subgrouping (PEIPS) assistance information when a UE is registered to the same or different PLMN/SNPN networks is proposed. The PEIPS assistance information includes PEIPS parameters such as a PEIPS subgroup ID that is used by the UE for monitoring paging with PEIPS for power saving. If the UE registers to the same PLMN/SNPN via 3GPP access and non-3GPP access, then the UE handles the PEIPS parameters as one common parameters. If the UE registers to different PLMN/SNPN via 3GPP access and non-3GPP access, then the UE handles the PEIPS parameters as two independent parameters.

A method comprises transmitting, to a terminal (101), at least one synchronization signal burst (150) in a time-limited channel access interval (405) of an open spectrum (409). The method further comprises transmitting, to the terminal (101), at least one paging signal (4004, 4005) in the channel access interval (405) of the open spectrum (409).

Systems, methods, and apparatus for paging early indication (PEI) and paging subgrouping are described herein. One described user equipment (UE) includes a set of one or more transceivers and a processor. The processor is configured to transmit, via the set of one or more transceivers, UE assistance information including a preferred time offset between receipt of a PEI by the UE and receipt of a paging occasion (PO) by the UE; transition from a sleep state to an awake state prior to the PO; and monitor for the PEI via the set of one or more transceivers, after transitioning to the awake state.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may operate in a radio resource control (RRC) inactive state of a discontinuous reception (DRX) mode. The UE may receive one or more synchronization signal blocks (SSBs) over a serving single frequency network (SFN) for a first notification zone, wherein the first notification zone comprises a plurality of cells. The UE may perform a channel measurement procedure using the received one or more SSBs. The UE may determine, based at least in part on a result of the channel measurement procedure, that a channel performance metric for the serving SFN of the first notification zone fails to satisfy a threshold. The UE may perform a cell reselection procedure to identify a cell of a neighboring SFN for a second notification zone that has a channel performance metric satisfying the threshold.

A wireless device sends a first radio resource control (RRC) message to a first base station. The first RRC message may indicate one or more first frequency band combinations that the wireless device is capable of communicating with the first base station. During an RRC connection with the first base station, a cell of a second base station for monitoring one or more downlink channels may be selected. One or more second frequency band combinations may be determined based on: one or more operating frequency bands of the cell; the one or more first frequency band combinations; and radio transceiver capability of the wireless device. During the RRC connection with the first base station, a second RRC message indicating the one or more second frequency band combinations may be transmitted to the first base station.

A communication system is disclosed in which a base station receives, from a core network entity, a paging request for paging an MTC device. The base station determines a paging occasion for sending to said MTC device paging related information, wherein the paging occasion is defined such that it identifies a plurality of subframes in which the paging related information can be sent and repeated. The base station sends (and repeats, as appropriate) the paging related information in the plurality of subframes identified by the paging occasion.
