Abstract: Apparatuses, systems, and methods for application awareness interworking between cellular systems. A wireless device may be configured to initiate an application during an ongoing procedure serviced by a first operating according to a first radio access technology (RAT), receive, from a first cellular system, an indication to switch to a second cellular system operating according to a second RAT, and delay the switch to the second cellular system until completion of the ongoing procedure. A network function may be configured to detect initiation of an application during an ongoing procedure serviced by a cellular system operating according to a first RAT, the application having associated application preferences, determine that the associated application preferences indicate a switch to a second cellular system operating according to a second RAT, and delay the switch to the second cellular system until completion of the ongoing procedure.

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 service device (e.g., a user equipment (UE), or other network component) can operate generate sidelink communications with peer UE devices based on PC5 unicast link to enable a direct peer-to-peer communication as part of PC5 vehicle-to-everything (V2X) communications. Radio status link detection can be configured based on a keep alive (KA) coordination scheme via the PC5 unicast link to monitor a status of the PC5 unicast link. A KA timer can be configured based on the KA coordination scheme via the PC5 unicast link. The KA coordination scheme is configured to reduce redundant KA requests in the PC5 unicast link to coordinate the direct peer-to-peer communication across the PC5 unicast link.

Abstract: This disclosure relates to transport link selection for an accessory wireless device in association with a companion device. The accessory device may communicate via a short range wireless communication link with the companion device. The companion device may detect an event and, based on the event, transmit assistance information to the accessory device. The accessory device may evaluate various conditions. The accessory device may select a transport link and/or short range link based at least in part on the received assistance information and/or the evaluated conditions.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for mitigation of secondary cell failures. A user equipment (UE) may establish communication with a macro cellular base station. The UE may perform a signal quality measurement of a small cell base station and compare the signal quality measurement to a threshold. Based on the signal quality measurement exceeding the threshold, the UE may attempt to additionally connect to the small cell base station. In response to a radio link failure of the second base station, the UE may modify the first threshold. In response to subsequent failures to additionally connect to the small cell base station using the modified first threshold, the UE may disable connections to the small cell base station.

Abstract: The exemplary embodiments relate to inter-radio access technology (iRAT) signaling reduction for a user equipment (UE). The UE may identify an inter-radio access technology (iRAT) event and determine that a predetermined condition is satisfied. The predetermined condition may be based on identifying a predetermined number of iRAT events within a predetermined time window. The UE may then implement a mechanism for iRAT signaling reduction based on the predetermined condition.
