Abstract: Methods, systems, and devices for wireless communications are described. An access and mobility management function (AMF) associated with a first radio access network (RAN) may identify a user equipment (UE) connected to a source base station of the first RAN. The AMF may receive a handover message including a voice call continuity handover trigger message indicating a handover of the UE to a target base station associated with a second RAN. In some examples, the AMF may transmit a bypass handover message to a second network device based a on the received handover message. In some cases, the bypass handover message may include the voice call continuity handover trigger message. In some examples, the second network device is a mobility management entity (MME) associated with an Evolved Universal Terrestrial Radio Access Network (E-UTRAN).

Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications systems may support a determination of user equipment (UE) capabilities, such as a category or a coverage level for broadcast or multicast content. In some cases, a radio interface may be configured to account for an indicated capability of a target UE. For example, a base station may receive an indication of a capability of a particular targeted UE. The capability of the targeted UE may be specified by a service provider to deliver multicast or broadcast content, and subsequently associated with a radio interface between the base station and the target UE. The radio interface may then be configured based on the indicated capability of the target UE, for example, by configuring a transport block size or bandwidth. The base station may then transmit broadcast or multicast content to the UE using the configured radio interface.

Abstract: Methods, systems, and devices are described for signaling protocols for proximity service functions in a wireless communication system. A first wireless device may identify a wireless relay requirement associated with the first wireless device. A proximity service protocol may be initiated between the first wireless device and a second wireless device based at least in part on the identified wireless relay requirement. The proximity service protocol may be initiated prior to an initiation of a communication data exchange between the first wireless device and the second wireless device. A relay link may be established, via the ProSe protocol, between the first wireless device and the second wireless device based at least in part on the identified wireless relay requirement.

Abstract: Techniques are discussed herein for supporting periodic or triggered location of a user equipment (UE) using 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 EDT. 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 connection with a RAN node but not with a core network to send the event report using EDT. The RAN node may then release the signaling connection, either immediately or after the LS returns a single response to the UE.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for communicating data between a user-equipment and network entity. For example, certain aspects of the present disclosure provide a method for wireless communication. The method generally includes receiving a message comprising a data packet from a user equipment (UE) during a communication session, and detecting whether the data packet is the last data packet for transmission or reception by the UE during the communication session. In certain aspects, the method also includes determining whether to process or discard the data packet based on the detection and whether a backoff timer is to be sent to the UE, and processing or discarding the data packet based on the determination.

Abstract: Methods, systems, and devices for wireless communication are described for inter-RAT mobility from a first radio access technology (RAT) to a second RAT, including cases in which different RATs correspond to different generations of networks. Approaches described herein include providing a preemptive indication of inter-RAT mobility for one or more geographic areas such to a user equipment (UE). The UE can thus use a mobility procedure to transition from the first RAT to the second RAT that is supported in the UE's location without first attempting an unsupported mobility procedure, reducing transition latency.

Abstract: Location services for a user equipment (UE) are supported with a Network Exposure Function (NEF) serving as a focal point for any location request. An entity that needs the location of the UE sends a location request to the NEF in the home PLMN or Visited PLMN for the UE. The location request includes, e.g., a type of location request, a required location accuracy, a required response time or some combination of these. The NEF determines whether to use a Gateway Mobile Location Center (GMLC) or a serving Access and Mobility Management Function (AMF) for the UE to obtain the UE location based on the content of the location request and sends the location request to the GMLC or serving AMF accordingly. Additionally, if the serving AMF is used, a serving base station may obtain the UE location and send the UE location to the serving AMF.

Abstract: Methods, systems, and devices for wireless communications are described that provide for a user equipment (UE) to report packet switched voice call capabilities to a base station. The UE may explicitly report voice call capabilities via one or more system-level parameters that are transmitted to the base station. The base station may operate in a first radio access network (RAN), such as a 5G or new radio (NR) RAN. In cases where the UE indicates a capability for packet switched voice calls via the first RAN, one or more voice calls may be established with the UE via the first RAN. In cases where the UE indicates that it is not capable of packet switched voice calls via the first RAN, the UE may fall back to a different RAN (e.g., a 4G or LTE RAN, a 3G RAN, or a 2G RAN) for voice calls.

Abstract: Methods, systems, and devices for wireless communication are described. Relocation of a user plane may be minimized through the exchange of communication session information between network nodes. For example, a connectivity session manager and an access and mobility manager may exchange information associated with a user equipment (UE) communication session to prevent unnecessary reestablishment of an existing communication session. In such cases, the access and mobility manager may receive a session management request from a UE and send a request including the session management request to the connectivity session manager. Based on the received message, the connectivity session manager may identify a continuity mode, select a user plane anchor for the communication session, and send a response message to the access and mobility manager. In some examples, the connectivity session manager and the access and mobility manager may exchange session area codes associated with the location of the UE.
