    Abstract: Various embodiments enable recovering from an out-of-service state in a wireless device. A processor may perform scans of a first acquisition database to acquire a first renewed service connection for a first subscriber identification module (SIM). The scans include first and second searches for first and second channels identified in first and second technology lists, respectively, from the first acquisition database, respectively, until either a renewed service connection is acquired or each of the first and second technology lists are exhausted. The first and second technology lists identify channels from first and second radio access technologies. A currently used channel of a second SIM acquired service is first on the first technology list. The processor may perform a full frequency scan to acquire a first renewed service connection for the first SIM in response to determining that each of the first and second technology lists were exhausted.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may run a process associated with a low latency. As such, the UE may operate in a mode to stay in a connected state with a network. The mode may include transmitting a keep alive message. Such message may be transmitted based in part on a keep alive timer with a shorter duration than a network traffic inactivity timer. If no communications occur between the UE and the network by the expiration of the keep alive timer, the UE may transmit a keep alive message to the network to maintain the connected state and reset the keep alive timer. Alternatively, if communications do occur, the UE may reset the keep alive timer. If the process is terminated, the UE may exit the mode for staying in the connected state, which may include canceling the keep alive timer.

    Abstract: Various embodiments include methods for adjusting timing advance values on a mobile communication device that includes receiving, on the mobile communication device, a timing advance adjustment value from a base station and determining whether the timing advance adjustment value exceeds an adjustment threshold. The mobile communication device may ignore the timing advance adjustment value in response to determining that the timing advance adjustment value exceeds the adjustment threshold, and may adjust a timing advance value stored on the mobile communication device by the timing advance adjustment value in response to determining that the timing advance adjustment value does not exceed the adjustment threshold.

    Abstract: Systems, methods, apparatuses, and media are provided for recovery of information from redundancy version packets in systematic encoding environments when a redundancy version packet containing primarily systematic information may be corrupted. A plurality of redundancy version packets may be received at a user equipment device from a transmission device. Each redundancy version packet of the plurality of redundancy version packets may be based on a same group of information bits. A first redundancy version packet of the plurality of redundancy version packets may contain more bits of the same group of information bits than do the other redundancy version packets of the plurality of redundancy version packets. The same group of information bits may be recovered based on one or more second redundancy version packets of the plurality of redundancy version packets but not based on the first redundancy version packet.
