Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for optimizing procedures to update a UE radio capability ID (URCID) when a UE moves to a new Public Land Mobile Network (PLMN) within a registration area. The techniques may help avoid unnecessary signaling traffic and reduce UE power consumption. An example method performed by a user equipment (UE) generally includes receiving at least one URCID assigned by a first PLMN; and taking one or more actions to delay or avoid updating the URCID when moving to a second PLMN in a same registration area as the first PLMN.

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: Certain aspects of the present disclosure relate to methods and apparatus relating to local area data network connectivity. In certain aspects, a method for use by a network device includes determining a set of available local area data networks (LADNs) for a user equipment (UE) based on a subscription of the UE to a set of data network names (DNNs) corresponding to the set of available LADNs and sending the UE information indicative of the set of available LADNs and a location of availability corresponding to each of the LADNs of the set of available LADNs.

Abstract: Certain aspects of the present disclosure provide techniques for traffic burst awareness in wireless systems. An application function, such as via an application server, can determine one or more burst parameters associated with a traffic flow for at least one service. The application function can send the one or more burst parameters a network. The burst parameters may include a burst factor associated with a minimum bit rate for providing service coverage for the traffic flow and/or a burst spread. A core network and/or access network (AN) entity can obtain the burst parameters and utilize the burst factor for communicating with a user equipment (UE). The CN and/or AN may use the burst parameters for admission control, resource allocation, and/or setting sleep mode parameters.

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.

Abstract: Aspects of the disclosure relate to mechanisms for interworking between legacy and next generation radio access technologies (RATs) in a communication network. In some examples, a handover from a next generation access network to a legacy access network may be performed via a next generation core network and a legacy core network. A handover request received at a next generation core network serving node may include an identifier of a target cell within the legacy access network. The next generation core network serving node may identify a legacy core network serving node to which the handover may be forwarded based on the target cell identifier. Packet data units may then be routed over the legacy access network and the next generation core network by mapping data flows in the next generation core network to packet data connections in the legacy access network.

Abstract: A method of wireless communication by a user equipment (UE) without a radio resource control (RRC) connection to a base station includes receiving system information from the base station and transmitting a data communication to the base station over a control plane without establishing an RRC connection with the base station. A UE in an RRC suspended state may transmit a data communication to the base station over a user plane without resuming an RRC connection with the base station. The data communication may comprise data and UE identity information and/or a cause indication. A base station may indicate resources in the system information for the transmission of the data communication information and receive the data communication over the control plane without establishing an RRC connection with the UE or over a user plane without resuming an RRC connection with an RRC suspended 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: Certain aspects of the present disclosure generally relate to wireless communications. In some aspects, a mobile device may receive configuration information, associated with configuring a state of the mobile device, via a unicast transmission, and may access a header-compressed broadcast transmission using the configuration information received via the unicast transmission. In some aspects, a network entity may transmit configuration information, to facilitate decompression of a header-compressed broadcast transmission, via a unicast transmission to a mobile device of a plurality of mobile devices, and may transmit the header-compressed broadcast transmission to the plurality of mobile devices in accordance with the configuration information.
