Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive an indication of a deadline for transmission of a protocol data unit (PDU) set, the indication of the deadline including one or more of: an indication of a jitter of the PDU set, an indication of a packet delay budget that is based at least in part on the jitter of the PDU set and a nominal PDU set delay budget (PSDB), or an indication of an absolute time of the deadline. The network node may transmit the PDU set at a time that is based at least in part on the indication of the deadline. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, in an inactive state, that uplink data is to be transmitted. The UE may determine whether a timing advance of the UE is valid. The UE may, if the timing advance is not valid, determine whether the uplink data satisfies a transport block size (TB S) threshold. The UE may, based at least in part on whether the uplink data satisfies the TB S threshold, selectively transmit the uplink data via an uplink random access channel (RACH) message or a configured uplink resource, or establish a radio resource control (RRC) connection for the uplink data. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit capability information indicating a first capability associated with a core network based UE subgrouping type and a second capability associated with a UE identifier based subgrouping type. The UE may receive, from a base station, an indication of whether the base station supports one or more UE subgrouping types, of the core network based UE subgrouping type and the UE identifier based subgrouping type. The UE may monitor a selected paging occasion based at least in part on the capability information and the indication. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an AMF may receive, from a user equipment (UE), a communication associated with a request for an identifier. The AMF may transmit, to the UE, the identifier, wherein the identifier is based at least in part on a synchronization signal block (SSB) periodicity and a number of paging frames per discontinuous reception (DRX) cycle.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication that a 5G media streaming (5GMS) service is partially available over a 5G multicast/broadcast service (5MBS). The UE may receive information that indicates a first set of resources of the 5GMS service that are accessible or delivered via 5G unicast, and a second set of resources of the 5GMS service that are accessible or delivered via 5MBS, wherein the second set of resources are hosted on a server of the UE. The UE may receive or transmit data associated with the 5GMS service. Numerous other aspects are described.

Abstract: The present disclosure relates to wireless communications, and more particularly to providing connectivity of a PC5 remote user equipment (UE) with UE-to-network (NW) relay access to the 5G core (5GC) via an IWF (e.g., N3IWF). In one aspect, a remote UE may be provided support for a network access stratum (NAS) connection with 5GC via an IWF. In another aspect, Access Traffic Steering, Switching and Splitting (ATSSS) support may be provided for a remote UE.

Abstract: Methods, systems, and devices for wireless communications are described. A multicast architecture may support flexible change between unicast and multicast operations and may support additional traffic types (e.g., Internet Protocol and Ethernet traffic). For example, the multicast architecture may include transmitting data over a shared multicast radio bearer (MRB) and/or specific data radio bearers (DRBs), a multicast user plane function (UPF) for supplying the multicast data to a base station, multicast data from different radio access networks (RANs), protecting the multicast data through creating a group key, ciphering the multicast data sent on the MRB using the group key, and transitioning the multicast data from a source RAN to a target RAN.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration for a multicast or broadcast radio bearer (MRB) in a radio link control (RLC) acknowledged mode (AM). The UE may determine an adjustment of an RLC AM transmission window of a base station. The RLC AM transmission window may be associated with retransmission of RLC packets associated with the MRB. The UE may synchronize an RLC AM reception window of the UE with the RLC AM transmission window based at least in part on determining the adjustment of the RLC AM transmission window of the base station. The RLC AM reception window may be associated with reassembly of RLC packets associated with the MRB. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration for a shared physical downlink shared channel (PDSCH). The UE may receive a first communication via the shared PDSCH and a first bearer based at least in part on the configuration, the first communication being one of a unicast communication or a multicast/broadcast communication. The UE may receive a second communication via the shared PDSCH and the first bearer or a second bearer based at least in part on the configuration, the second communication being the other of the unicast communication or the multicast/broadcast communication. Numerous other aspects are provided.

Abstract: A core network receives data from at least one of an Application Function (AF), a Data Network (DN), or a User Equipment (UE). A Session Management Function (SMF) processes the data for transport with a low overhead as a session management (SM) payload over a Non Access Stratum (NAS) protocol. The data may be received from an ΔF or DN external to the core network and may be processed to transport the data to the UE based as a SM payload. The data may be received as uplink data from a UE, e.g., in an SM payload. The SMF may processed the SM payload to obtain the data and may transport the data to the AF or DN. The SMF may perform IP header compression, data encryption based on an SMF encryption key, and/or buffering of data for a UE in an idle mode.
