Abstract: A user equipment (UE) may receive a quality of service (QoS) flow for a multicast or broadcast service that is secured with a multicast-broadcast key. The UE may transmit a data session establishment request to a service management function (SMF) for the multicast or broadcast service. The UE may receive at least one multicast-broadcast key for the PDU session. The UE may determine a radio bearer (RB) configuration for the multicast or broadcast service. The UE may receive one or more QoS flow packets for the multicast or broadcast service over the RB. The UE may decode the one or more QoS flow packets using the at least one multicast-broadcast key, or a key derived from the at least one multicast-broadcast key. Decoding may include decrypting, verifying the integrity, or a combination thereof.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes receiving a network access control broadcast including access control criteria associated with connecting to a base station, determining an access category associated with the UE and an access identity of the UE associated with the access category, where the access category of the UE is specific to a reduced capability classification of the UE, and selectively performing a random access procedure to connect to the base station in accordance with the access control criteria, the access identity of the UE, and the access category associated with the UE.

Abstract: Methods, systems, and devices for wireless communications are described that provide for truncated identification indicators. A user equipment (UE) may receive control signaling indicating a truncating configuration for an identification indicator. The truncating configuration may indicate a set of bits within an initial identification indicator to remove to generate a truncated identification indicator. The UE may remove the indicated set of bits and transmit the truncated identification indicator to a base station. The base station may receive the truncated identification indicator and reconstruct the initial identification indicator according to the truncating configuration. The base station may reconstruct the initial identification indicator by adding the set of bits (e.g., removed by the UE to generate the truncated identification indicator) to the truncated identification indicator.

Abstract: Methods, systems, and devices are described for wireless communications. A wireless communication system may use access preferences to indicate a preferred access for communicating signaling for a control plane service. In some aspects, an AMF and a UE may establish access preferences for one or more control plane services and communicate signaling for the control plane service based on the established access preferences. In some cases, the UE may transmit modified access preferences for a control plane service to the AMF, and the UE and AMF may communicate signaling for the control plane service based on the modified access preferences. In some aspects, an AMF may also restrict the accesses used by a control plane service. A UE may also request that certain accesses are restricted for use by a control plane service.

Abstract: Methods, systems, and devices for wireless communication are described that provide for identification, on a per-PLMN basis of a type of core network associated with each PLMN in a list of networks associated with a base station. A user equipment (UE) may receive the list of networks and, based at least in part on the type(s) of core network accessible via each PLMN and a capability of the UE, initiate a connection establishment with a PLMN and associated core network. In some cases, UEs that are not capable of connections with a first type of core network (e.g., a 5G core network) may be restricted from camping on a cell or PLMN that may provide only connections with the first type of core network (e.g., a 4G core network).

Abstract: Techniques are discussed herein for supporting periodic or triggered location of a user equipment (UE) using control plane (CP) optimization with optional use of Early Data Transmission (EDT). A location server (LS), such as a 5G LMF, sends a request to a UE for periodic or triggered location and includes a request and/or criteria for using CP optimization. After confirming the request, the UE monitors for periodic or triggering events and, for each detected event, sends an event report to the LS which may include location information. In embodiments, the UE establishes a signaling association with a RAN node to send the event report using CP optimization and optionally using EDT. The RAN node may then release the signaling association after the LS returns a single response to the UE.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for handling mobility between areas with heterogeneous network slices in wireless communications systems operating according to new radio (NR) technologies. An exemplary method that may be performed by a UE includes receiving an indication that a network slice is not available, entering a connection management idle (CM-IDLE) state, and initiating a registration procedure with an access and mobility management function (AMF) subsequent to entering the CM-IDLE state.

Abstract: Aspects of the disclosure relate to a method of operating a user equipment for wireless communication with a network. In some aspects, the UE establishes a connection to a network and obtains a control plane message from the network. The control plane message may include one or more types of policy information if a size of the one or more types of policy information is less than or equal to a maximum payload size of the control plane message, or information indicating at least a network location from where the one or more types of policy information may be obtained by the UE over a user plane if the size of the one or more types of policy information is greater than the maximum payload size of the control plane message, or a combination thereof. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a request to establish a multicast session. The request may identify a multicast service session including a multicast quality of service flow. The UE may receive, from a base station wirelessly communicating with the UE, an indication of communication resources for the UE to use to receive multicast packets of the multicast service session from a content provider via a tunnel between a first network node and the base station. The tunnel may be established for the multicast service session based on identifying that the multicast service session lacks an existing tunnel between the first network node and the base station. The UE may identify a discontinuous reception (DRX) cycle for the multicast service session, and receive the multicast packets from the base station according to the indicated communication resources and the identified DRX cycle.
