Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a network entity within a wireless communications network. The UE may transmit a request for information to the network entity and, in response to the request, the UE may receive the requested information from the network entity. For example, the UE may request data from one or more data repositories associated with the network entity. In some examples, the information request may be associated with one or more measurements associated with operations of the network. In some instances, the UE may use a machine learning model to perform training or inference based on the information associated with the one or more measurements.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may support dual connectivity. That is, the UE may establish communications with a master node and a secondary node of a wireless communications network. The master node may correspond to a master cell group (MCG) and the secondary node may correspond to a secondary cell group (SCG). In some examples, as described herein, the UE operating in dual connectivity may collect data for optimization of the wireless communications network or upon detecting a failure associated with the master cell group or the SCG and transmit the collected data to a network entity (e.g., one of the master node or the secondary node), where the collected data is based on the SCG being in a deactivated state. In some examples, upon receiving the collected data, the network entity may attempt to recover from the failure.

Abstract: Capability exchange enhancements include filtering and/or indexing. In some aspects, a user equipment (UE) determines UE capabilities to be reported to a network based on one or more of: one or more enquiries from the network, received system information, a home operator policy, configuration associated with public land mobile network (PLMN) information of one or more networks, a user preference, or a service type. In other aspects, a UE may report a subset of UE capabilities for features used for the connection establishment. Following connection establishment, the UE may use an identifier to communicate a more complete set of modes of operation that the UE is currently capable of performing. Base stations of the network may share the reported subset so that the UE may avoid transmitting the subset to a target base station.

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: Wireless communications systems and methods related to improving user equipment (UE) mobility performance are provided. A wireless communication device camps on a first cell operating on a first carrier frequency. The wireless communication device receives, from the first cell, cell selection priority information indicating a priority for each of a plurality of carrier frequencies. The wireless communication device evaluates each of two or more candidate cells over an evaluation time duration associated with each candidate cell, wherein an end time of the evaluation time duration of a candidate cell associated with a lower priority carrier frequency is configured to be after an end time of the evaluation time duration of a candidate cell associated with a higher priority carrier frequency. The first wireless communication device selects a second cell from the two or more candidate cells for camping based at least in part on the evaluation of the second cell.

Abstract: The disclosure provides for a user equipment (UE) to change from a first network to a second network for an internet protocol (IP) multimedia subsystem (IMS) call. Initially, the UE has a connection to a first network providing an IP address for the UE. The UE may receive, via the first network, a message indicating an incoming IMS call. The UE may transmit one or more IMS call setup messages on the first network at an IP layer. The UE may change the connection from the first network to a second network that uses a same identifier for the UE (e.g., the IP address). The UE may complete setup of the IMS call on the second network using the same identifier for the UE.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for coordinating UE capabilities across RATs. In some cases, a UE may provide an indication of one or more first sets of capabilities of the UE to operate in a first RAT network that are compatible with one or more second sets of capabilities of the UE to operate in a second RAT network. Indicating the sets of capabilities may require less signaling overhead than explicitly signaling all possible combinations of capabililites.

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.
