  • 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.

  • Publication number: 20180035397
    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.

  • 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.

  • Publication number: 20170265205
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be communicating on a radio frequency spectrum band of a first radio access technology (RAT) using a set of antennas. The UE may reconfigure at least one antenna of the set of antennas to perform a first scan on the radio frequency spectrum band of a second RAT. The UE may determine, based on the first scan, whether to reconfigure a remaining portion of the antennas of the set of antennas to perform a second scan on the radio frequency spectrum band of the second RAT.

  • Patent number: 9743459
    Abstract: Certain aspects of the present disclosure relate to techniques and apparatus for optimizing long term evolution (LTE) connected discontinuous reception (CDRX) for single radio hybrid tune away devices. Certain aspects provide a method for wireless communications by a user equipment (UE). The method generally includes entering a DRX mode wherein the UE alternates between an activity period and an inactivity period while connected to a first radio access technology (RAT) network, tuning away from the first RAT network for a tune away period to monitor signals in a second RAT network, determining when an inactivity timer for the DRX mode expires or will expire, and adjusting a value of the inactivity timer based, at least in part, on the determination.

  • Publication number: 20170150548
    Abstract: Various aspects described herein relate to a user equipment (UE) that can receive a configuration for a radio bearer with an SCell in a radio resource control (RRC) reconfiguration procedure initiated by a primary cell (PCell) serving the UE. A component carrier with the SCell can be activated based at least in part on receiving a control element indicating to activate the component carrier for the radio bearer. It can be determined whether a first deactivation timer, for deactivating the component carrier with the SCell after a period of detected inactivity on the SCell, is configured by the PCell. A second deactivation timer can be configured for deactivating the component carrier with the SCell based at least in part on a determination that the first deactivation timer is not configured by the PCell or that a first configured duration of the first deactivation timer achieves a threshold.
