Abstract: Smart vehicle-to-everything (V2X) preemptive connections for emergency and/or potential accident scenarios. A V2X-enabled vehicle may determine a current route of the vehicle and high-risk areas through which the vehicle may travel (e.g., a hospital zone, high pedestrian traffic area, etc.). The vehicle may determine a distance (d) from a beginning of the high-risk area and begin establishing a V2X connection upon reaching the determined distance. The V2X-enabled vehicle may also, or alternatively, pre-emptively establish a V2X connection upon detecting an event initiative of an emergency, a hazardous situation, or a potential emergency. Examples of such events may include a sharp turn, a vehicle speed exceeding a speed threshold, a sudden acceleration or declaration, etc. A preemptive V2X connection may, for example, enable vehicles to begin communicating with one another faster in case of a threat, emergency, or unsafe conditions for vehicles in the area.

Abstract: Techniques, described herein, may enable a vehicle to engage in vehicle-to-everything (V2X) communications via PC5 sidelink (SL), even when the vehicle does not have a global positioning system (GPS) or other type of satellite signal. While receiving a satellite signal, the vehicle may pre-store future geographic locations based on a travel route and upon detecting a loss of the satellite signal, the vehicle may estimate a geographic location of the UE based on one or more types of information, such as mapping or navigation capabilities of the UE, a travel time since the signal failure or last estimated geographic location, a travel velocity since the since the signal failure or last estimated geographic location, etc. The vehicle may determine, based on an estimated geographic location, that physical resources are appropriate for SL communications and begin using the physical resources accordingly.

Abstract: The present application relates to improving a roaming service. In an example, user equipment (UE) initiates a cell selection process to choose between a first cell and a second cell. The UE evaluates a first uplink (UL) channel condition of the first cell and a second UL channel condition of the second cell based on the initiation. The UE selects the first cell or the second cell based on the evaluated first UL channel condition and second UL channel condition. The UE initiates a random access channel (RACH) procedure based on the selected first cell or second cell.

Abstract: The present application relates to devices and components including apparatus, systems, and methods for IMS registration in wireless networks.

Abstract: This disclosure relates to techniques for a wireless device to determine a radio access technology availability indicator to present. A wireless device may establish a wireless link with a cellular network via a cell that operates according to a first radio access technology. The wireless device may determine if access to the cellular network is also available via a cell that operates according to a second radio access technology, by configuration by the serving cell or from another standalone cell. The wireless device may select a radio access technology availability indicator to present based at least in part on determining if access to the cellular network is also available via a cell that operates according to the second radio access technology.

Abstract: This disclosure relates to methods and devices for a user equipment device (UE) to perform band measurements and provide a pruned measurement report to a base station. A first connection is established between the UE and a base station, and a configuration message is received from the base station. The configuration message identifies a plurality of bands for which the UE is to provide measurement reporting. The UE determines whether a band combination of the plurality of bands has an aggregate bandwidth that is greater than the aggregate bandwidth of the first connection and whether a signal quality metric of the determined band combination is greater than a predetermined threshold. Responsive to these determinations, the UE performs band measurements on the bands of the band combination and transmits a pruned measurement report to the base station.

Abstract: Apparatuses, systems, and methods for enhancement of Wi-Fi calling for DSDS user equipment devices (UEs). The UE may register a first connection supported by a first SIM with IMS for VoWiFi based on a determination to prefer VoWiFi for the first SIM. The first SIM may be associated with a first subscription to a first RAN. The UE may include a second SIM that may be associated with a second subscription to a second RAN. The UE may register a second connection associated with the second SIM with the IMS for VoWiFi and/or VoLTE and initiate/receive, via the first connection supported by the first SIM, a VoWiFi call. A recommendation to handover the VoWiFi call from Wi-Fi to cellular data may be received and, based, at least in part, on the recommendation, the UE may register a second connection associated with the second SIM for IWLAN over cellular data.

Abstract: A device, system and method for a user equipment (UE) to opportunistically utilize the wireless capabilities of a paired device. The UE is configured to establish a first cellular network connection based on a first subscription, a second cellular network connection based on a second subscription and a connection to a further UE based on a short-range communication protocol. The UE identifies a predetermined condition and transmits an indication to the further UE based on the predetermined condition. The further UE establishes a further cellular network connection in response to the indication and the further cellular network connection is based on one of the first subscription or the second subscription. The UE then declares no service for one of the first cellular network connection or the second cellular network connection based on the further cellular network connection.
