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.

Abstract: A method, device, computer readable storage medium and integrated circuit for providing user equipment (UE) capability information to a network. The method includes receiving a request from a network for radio access capabilities of the UE, determining a first plurality of band combinations that the UE is capable of utilizing for communications with the network, determining a number of band combinations that are to be included with a message generated in response to the request, ordering the plurality of band combinations into a prioritized order of band combinations based on at least one priority factor, generating the message that includes the radio access capabilities, wherein the message includes a second plurality of band combinations that are based on the prioritized order and the number of band combinations that are to be included with a message and transmitting the message to the network.

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.
