  • 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: 20150319666
    Abstract: Methods and apparatus for wireless communication for improving handover between a network and a user equipment (UE) when a measurement report is received. Aspects of the methods and apparatus relate to determining the quality of a serving cell associated with a fast handover performance threshold. When the fast handover performance threshold is breached, the UE may transmit a measurement report requesting a handover to a target cell. Upon requesting a handover to a target cell when the fast handover performance threshold is breached, the UE receives a handover trigger allowing handover to a target cell.

  • Publication number: 20150280803
    Abstract: In an aspect of the disclosure, a method, a computer program product, and an apparatus are provided. The apparatus switches from a multiple receive diversity (RxD) on state to a RxD off state upon detecting a condition is in a certain state. The condition may be a high measure of correlation between a first antenna and a second antenna, or a high level of imbalance between the first antenna and the second antenna. The apparatus also periodically switches back to the RxD on state to determine if the condition remains in the certain state. The time period between entries into the RxD on state is dynamically adjusted as a function of prior conditions.

  • Publication number: 20140133319
    Abstract: In a TD-SCDMA user equipment (UE) with multiple receive chains, receive diversity may be implemented where multiple receive chains may simultaneously activate to perform reception on downlink signals. Receive diversity may be enabled when single chain reception provides undesired results and when receive diversity will not impact power consumption too much. A state machine may be implemented to control receive diversity operation based on operating conditions such as an error rate, signal-to-interference ratio, and other factors.

  • Publication number: 20130235956
    Abstract: In wireless communication systems, received signal estimation and detection is computationally intensive. During such processing, received signal matrices may be conditioned prior to inversion to improve stability. In particular, code domain conditioning, followed by time domain conditioning prior to inversion results in improved receiver performance. Such code and time domain conditioning may be particularly suited to a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) system where code values are not averaged out of a received signal matrix.
