Abstract: Apparatuses, systems, and methods for a wireless device to perform negotiation of bearer type configuration and/or related parameters. A user equipment device (UE) and/or network may determine a bearer configuration and/or other parameters based on information or measurements of the UE. The UE and the BS may exchange data using a negotiated configuration.

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: Apparatuses, systems, and methods for a wireless device to perform detection and mitigation of data stalls. The mitigation may occur during and/or at initiation of a data connection. The wireless device may establish a data connection(s) with a network over a Wi-Fi or cellular interface and monitor the data connection(s) for a data stall condition(s)/hint(s). The wireless device may perform a remedial action(s) responsive to detection of a data stall condition(s)/hint(s), including initiating a service recovery of the cellular interface, initiating a radio access technology (RAT) upgrade procedure, and/or initiating a handover procedure to a neighbor cell.
