  • Publication number: 20190082446
    Abstract: Various embodiments for managing uplink transmissions in a mobile communication device may include receiving, on a first subscription of the mobile communication device, an uplink grant from a first network and determining whether a tune-away from the first subscription to a second subscription of the mobile communication device is scheduled to occur during reception of a response message sent from the first network following an initial transmission of a data packet according to the uplink grant. The mobile communication device may use a block error rate and a buffer status report index of a connection between the first subscription and the first network to determine how to manage uplink transmissions following the tune-away.

  • Patent number: 9942090
    Abstract: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to predicting a system loss event and/or proactive system recovery. Aspects of the present disclosure relate to techniques and apparatus for system loss event (e.g., radio link failure event) geo-coding and proactive system recovery. According to certain aspects, a user equipment (UE) may generate and store information about one or more system loss events associated with the UE. The UE may then predict one or more other system loss events associated with the UE based on this information and take action, based on the prediction to continue communication of the UE.

  • Patent number: 9854601
    Abstract: A method, device and system provide improved throughput for network subscriptions in multi-SIM, multi-standby wireless devices by triggering false or fake NAK/Tx messages prior to the tune-away. The technique includes receiving and decoding communications from a node at a user equipment during a first subscription communication mode; in response to a communication from the node to the user equipment after a certain time period prior to a tune away period in which the user equipment communicates in a second subscription communication mode, communicating a fake NACK message from the user equipment to the node; and after the tune away period ends, receiving communications at the user equipment from the node and responding with an ACK message.

  • Publication number: 20170324519
    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.
