Abstract: This disclosure relates to performing implicit radio resource control state transitions in a cellular communication system. A wireless device may establish a radio resource control (RRC) connection with a cellular base station. A data inactivity timer length and a target RRC state for implicit RRC transitions may be determined. A data inactivity timer having the determined data inactivity timer length may be initiated. It may be determined that the data inactivity timer has expired. The wireless device may transition to the target RRC state based at least in part on determining that the data inactivity timer has expired.

Abstract: A network controller, a user equipment (UE) device, and associated methods for adaptively prioritizing simultaneous unicast and multicast communications based on traffic classes. The UE may determine whether each of a unicast communication and a multicast communication are associated with a foreground application or a background application. The UE may further determine whether each of the unicast communication and the multicast communication are high priority or low priority. The UE may then buffer one of the unicast or multicast communications based on the whether it is associated with a foreground or background application, whether it is high or low priority, and whether it is a unicast or multicast communication.

Abstract: A device and method for transmitting user equipment capability information to a network. In a first mechanism, the device and method determines the carrier aggregation (CA) combinations supported by the user equipment that are relevant to the user equipment. in a priority order to the network. The relevant CA combinations may be determined based on most recent camped bands and the neighbor bands of the most recent camped bands. In a second mechanism, the device and method orders the relevant CA combinations into a prioritized list according to which CA combination have priority based on selected priority factors. Subsequently, the user equipment broadcasts the prioritized list of CA combinations to the network.

Abstract: A device and method for transmitting user equipment capability information to a network. In a first mechanism, the device and method transmits carrier aggregation (CA) combinations supported by the user equipment in a priority order to the network. The priority order may be determined based on most recent camped bands and the neighbor bands of the most recent camped bands. In a second mechanism, the device and method transmits indicators corresponding to types of gapless measurements, where when an indicator is set to the user equipment being incapable of performing the type of gapless measurement, the capability message does not include individual indications for the bands for that type of measurement.

Abstract: Embodiments for performing a fast return to Wi-Fi following completion of a cellular voice call are provided. These embodiments include detecting that a device has switched from communicating over a Wi-Fi interface to communicating over a cellular interface; determining the earliest time that the device can switch back to Wi-Fi; and instituting the switch. In some embodiments, the process of performing a fast return to Wi-Fi is carried out by devices having small form factors, such as smartwatches and other wearables, which may be susceptible to coexistence and peak power problems. The fast return to Wi-Fi embodiments disclosed herein allow a device to perform a voice call over a cellular interface when Wi-Fi calling is not available, and switch over to a Wi-Fi interface immediately upon completion of the voice call in order to conserve battery life, achieve higher data speeds, and avoid high costs associated with cellular data transmissions.

Abstract: This disclosure relates to cellular service recovery techniques using cell-specific cellular service history information for an accessory device. According to some embodiments, cellular service history information relating to cellular service loss occasions for each of one or more cells from which the accessory device has previously lost cellular service may be stored. It may be determined that cellular service loss is currently occurring from a cell for which cellular service history information relating to cellular service loss occasions is stored. Cellular service recovery may be attempted using the cellular service history information relating to cellular service loss occasions for the cell from which the current cellular service loss is occurring.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) and/or cellular network to perform to perform capability updates. Under at least some circumstances, the UE may use a non-cellular (e.g., non-3GPP) access to transmit updated capability information to a cellular network. Elements of the core of the cellular network may provide an identifier corresponding to the updated capability information to the UE for use in future registrations with the cellular network. Further, the core network may provide the updated capability information to a cellular radio access network associated the cellular network. The UE and the cellular network may communicate according to the updated capability.

Abstract: A user equipment (UE) displays a list of available networks for manual network selection. The UE detects multiple networks during a public land mobile network (PLMN) scan, wherein the multiple networks include one or more PLMNs and one or more stand-alone non-public networks (SNPNs), generates a manual network selection list that includes at least i) the one or more PLMNs or ii) the one or more SNPNs, determines a sequence in which entries of the manual network selection list are to be displayed at the UE, displays a graphical user interface (GUI) that includes a representation of the manual network selection list and registers with one of the multiple networks in response to user input.

Abstract: This application describes methods and apparatus to manage data transport across multiple radio links for 5G-capable wireless devices. Under certain criteria, including performance of at least one radio link, a mobility state of a 5G-capable wireless device, and data transport requirements for a latency sensitive application session, the 5G-capable wireless device sends buffer status report (BSR) requests for one or more both of the radio links to prioritize and transition uplink (UL) data between radio links before a measurement reporting threshold is met. In some embodiments, the 5G-capable wireless device proactively sends BSR requests for radio resources before the UL data is generated by the latency sensitive application session. In some embodiments, the 5G-capable wireless device duplicates UL data for the latency sensitive application session across multiple radio links.

Abstract: A user equipment (UE) is configured to store information related to network slices. The UE receives network slice related information associated with a first public land mobile network (PLMN), stores the network slice related information in a database locally at the UE, identifies a predetermined condition and removes at least a portion of the network slice information associated with the first PLMN based on camping on a second PLMN and the predetermined condition.
