  • Patent number: 9565687
    Abstract: Various embodiments include methods for reporting quality metrics of a wireless communication device to a network that includes scheduling, on the wireless communication device, a tune-away from a first carrier of a first subscription to a second subscription. Quality metrics of the first carrier before the tune-away begins are calculated and stored as frozen quality metrics. During the tune-away, the wireless communication device sends the stored frozen quality metrics to the network. The stored frozen quality metrics may continue to be sent to the network as long as the duration of the tune-away is shorter than a time threshold. If the duration of the tune-away exceeds the time threshold, the wireless communication device may calculate and send actual quality metrics of the carrier to the network.

    Abstract: Embodiments described herein relate to systems and methods for scheduling subscriptions in a user equipment (UE) having at least a first receive radio and a second receive radio, including receiving, by the first receive radio, a broadcast activity for a first subscription and receiving, by the second receive radio, a reception activity for a second subscription. A trigger event is detected while the broadcast activity for the first subscription is being received by the first receive radio and the reception activity for the second subscription is being received by the second receive radio. In response to detecting the trigger event, the reception activity for the second subscription is received by the first receive radio and the broadcast activity for the first subscription is received by the second receive radio.

  • Publication number: 20160198352
    Abstract: Methods and devices are disclosed for managing diversity tune-away on a wireless communication device configured with at least two radio frequency (RF) receive resources associated with a connection in a high speed data network. The wireless device may monitor data communications and downlink channel conditions in the high speed data network, and determine whether a diversity tune-away mode has been entered. Upon determining that the diversity tune-away mode has been entered, the wireless device may perform a deliberate acknowledgment procedure by ignoring normal error detection for received data and sending an acknowledgment message for the received data to the high speed data network. The wireless device may determine whether the diversity tune-away mode has ended, and in response to determining that the diversity tune-away mode has ended, and halt the deliberate acknowledgment procedure in response to determining that the diversity tune-away mode has ended.

  • Publication number: 20160134317
    Abstract: Methods and devices for implementing dynamic receive mode management to improve data throughput and paging performance on a multi-subscriber identification module (SIM) wireless communication device may include detecting, on a protocol stack associated with a first SIM, an active communication in a first network, detecting, on a protocol stack associated with a second SIM, an idle mode paging cycle in a second network, prompting entry into a selected dual receive mode on the shared RF resource, and monitoring at least one performance metric for the idle mode paging cycle associated with the second SIM while in the dual receive mode. Based on the monitored performance metric while in the dual receive mode, the wireless communication device may determine whether paging performance is degraded for the second SIM, and if so, trigger entry into a fallback mode on the shared RF resource.

  • Publication number: 20160095033
    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus, e.g., UE, suspends a discarding process of data packets associated with a first RAT during tune away by the UE to a second RAT by stopping a discard timer. The UE restarts the discarding process in response to an occurrence of a triggering event. The triggering event may occur when the UE tunes back to the first RAT, or when a duration of the UE tune away to the second RAT exceeds a threshold. The discarding process may be restarted by resuming the discard timer at the point in time where it was stopped or by resetting the timer to zero.
