Abstract: Aspects of the present disclosure provide techniques that allow the user equipment (UE) that initiated single radio voice call continuity (SRVCC) handover during an active voice session from 5G new radio (NR) to 3G legacy system to effectively transition back from 3G legacy systems to 5G NR systems after conclusion of the active voice session. In one example, the UE may override radio resource control (RRC) connection release with evolved universal terrestrial radio access network (E-UTRAN) frequency information that may direct the UE to camp in E-UTRAN cell (LTE cell). In another example, the UE, as a local policy or configuration, may override the UTRAN cell information when the UE is registered in next generation radio access network (NR) cell as 5G capable UE.

Abstract: In an embodiment, a drone-coupled UE determines whether the drone-coupled UE is engaged in a flying state, and transmits a message to a network component of a terrestrial wireless communication subscriber network that indicates a result of the determining. The network component receives the message from the drone-coupled UE. In an embodiment, a network component of a terrestrial wireless communication subscriber network determines whether the drone-coupled UE is engaged in a flying state based on the message from the drone-coupled UE. The network component then applies protocols based on the determining.

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.

An example method of wireless communications obtaining, by a first wireless communication device from a second device associated with a second network, information regarding whether the first wireless communication device is within coverage by a first network. The first wireless communication device supports dual connectivity with the first network and the second network. The method also includes determining, based at least in part on the information, whether to display an icon indicating that the first wireless communication device is connected to the first network. The method further includes in response to a determination to display the icon, displaying, by the first wireless communication device, the icon on a display coupled to the first wireless communication device.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for enabling access control in a connected mode, idle mode, and an inactive state. An exemplary method generally includes receiving access control information associated with one or more services used by the UE for communicating with the wireless communications network, receiving a request to transmit traffic using the one or more services, checking a type of the traffic against the access control information, and scheduling the traffic for transmission if the type of the traffic satisfies one or more criteria in the access control information based on the checking.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for improving voice over new radio (VoNR)-to-voice over long term evolution (VoLTE). An example method generally includes communicating with and camping on a next generation node B (gNB) in a 5G new radio (NR) system; initiating a voice call with the gNB; receiving a 5G NR-to-long term evolution (LTE) handover command in response to initiating the voice call; performing a handover procedure in response to the handover command; detecting a failure in the handover procedure; and taking one or more actions in response to detecting the failure in the handover procedure.

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.
