Abstract: A network entity, such as a user equipment (UE), may request that a network provide multicast and broadcast services, e.g., where the request includes entity preferences such as network slice selection information. The network may provide information regarding provision of such services, where the information may include, for example, whether a service will be provided via a user plane or a control plane connection, network slice information, additional connections to be formed, separate encryption for such connections, etc. A Multicast/Broadcast Network Function (MBNF) may be used to establish such connections and manage a broadcast and multicast sessions. The MBNF may, for example, manage groups of entities, check an entity's access privileges for services, communicate with the a Management and Network Orchestration (MANO) system to reserve resources, and send data to entities over a shared control plane connection.

Abstract: Radio resource management measurements for new radio unlicensed are performed that are based on a measurement model where a missed received signal transmission opportunity indicator is provided to higher layers to adapt the measurement functions performed by the radio resource control when a missed received signal transmission opportunity is detected. Radio link monitoring for new radio unlicensed is performed based on in-sync or out-of-sync indications that are based on the estimated radio link quality in combination with missed radio link monitoring reference signal transmission opportunities.

Abstract: Methods and apparatus are disclosed pertaining to paging for Unlicensed New Radio (NR-U). Methods include means to: perform paging using multiple paging occasions (POs) during a DRX Cycle, perform paging using a paging window, perform paging using a PO comprised of multiple sweeps and/or repetitions, signal DL channel access indication for paging, and perform paging using dynamic DRX. In accordance with one embodiment, an apparatus may receive a signal comprising a plurality of POs, wherein each PO comprises a plurality of physical downlink control channel (PDCCH) monitoring occasions. The apparatus may monitor, based on receiving an identifier associated with the apparatus, a portion of the plurality of paging occasions. The apparatus may detect, in a PDCCH monitoring occasion of the plurality of PDCCH monitoring occasions in the monitored portion, paging downlink control information (DCI).

Abstract: The present application at least describes a method for obtaining channel access in a network. The method includes a step of selecting, via a gNodeB, a spatial filter from a first set of spatial filters to perform listen before talk (LBT). The method includes a step of detecting, via the gNodeB, a channel in an idle state. The method also includes a step of obtaining, a directional channel occupancy time (COT) in the channel in a direction of the selected spatial filter. The method also includes a step of transmitting, to a node, a channel access indicator transmission (CAI-T) on a beam in the cot via a spatial filter of a second set of spatial filters. The method further includes a step of receiving, from the node, a channel access indicator response (CAI-R). The method further includes a step of sensing, via short channel sensing and via the spatial filter or another spatial filter of the second set of spatial filters, the channel is clear. The method even further includes a step of sending, via the channel, information to the node using one or more spatial filters of the second set of spatial filters. Other embodiments of this aspect include corresponding computer systems, apparatus, and computer programs recorded on one or more computer storage devices, each configured to perform the actions of the methods.
