Abstract: Various embodiments provide methods implemented in a mobile communication device (e.g., a multi-RAT communication device) for maintaining at least one separate RGS value for each of a plurality of RATs operating on the mobile communication device. Specifically, a device processor on the mobile communication device (e.g., a crystal oscillator manager) may maintain a separate, up-to-date RGS value for each of the plurality of RATs and may associate each of the plurality of RATs with their respective RGS values. By keeping track of the plurality of RATs' respective RGS values, the device processor may ensure that an appropriate RGS value is used to facilitate each RAT's individual operations, such as acquisition/re-acquisition operations, sleep scheduling calculations, and handover/inter-RAT measurement operations. As a result, various embodiments may improve the performance of each RAT and the overall performance of the mobile communication device.

Abstract: Methods, devices, and systems embodiments enable recovering from an out-of-service state in a wireless device. A processor may perform scans of first and second acquisition databases to acquire a first renewed service connection for a first subscriber identification module (SIM). The scans include first and second searches for first channels identified in first and second technology lists, respectively, from the first and second 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 a most recently used radio access technology of the respective acquisition databases. 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: Aspects of the disclosure provide techniques for improving uplink transmit power control at a user equipment (UE). When the UE is communicating with multiple cells using Multi-flow High-Speed Downlink Packet Access (MF-HSDPA), the UE may control its uplink power based on an improved MF-HSDPA uplink power control algorithm, which is different from an or-of-downs (OOD) transmit power control. In handover, a UE may determine its transmit power to be less than a transmit power requested by a high-speed cell and more than an OOD transmit power.

Abstract: In various aspects, the disclosure provides the capability for a UE to implement a partial PLMN scan, providing quick results to a user's request for a manual PLMN scan, in a way that is expedited relative to the conventional method of providing PLMN results only when a full scan is completed. In further aspects, the disclosure provides for various optimizations to expedite a PLMN scan, which may be implemented either with the partial PLMN scan, or in a full PLMN scan, to further expedite the provision of PLMN scan results to the user.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a predicted tune-away for a set of voice frames. In some aspects, the user equipment may alter a vocoder rate from a first vocoder rate to a second vocoder rate that is less than the first vocoder rate based at least in part on determining the predicted tune-away for the set of voice frames. In some aspects, the user equipment may drop, in connection with an occurrence of the predicted tune-away, a subset of packets for a time period corresponding to the predicted tune-away. Numerous other aspects are provided.

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.

Abstract: Embodiments include systems and methods for managing inter-radio access technology (IRAT) procedure concurrency between subscriptions on a multi-subscription multi-active communication device. A device processor may identify a higher-priority subscription and a lower-priority subscription on the multi-subscription multi-active communication device. The device processor may determine whether an IRAT procedure on the lower-priority subscription will overlap in time with an IRAT procedure on the higher-priority subscription. The device processor may calculate a deferral time period for the lower-priority subscription in response to determining that the IRAT procedure on the lower-priority subscription will overlap in time with the IRAT procedure on the higher-priority subscription. The device processor may defer performance of the lower-priority subscription IRAT procedure using the deferral time period in order to perform the IRAT procedure on the higher-priority subscription, and may perform the IRAT procedure on the lower-priority subscription after the deferral time period.

Abstract: Various embodiments include methods, systems, and devices for communicating with a first network and a second network using a mobile device having a single radio comprising a transmitter and a receiver. The transmitter and the receiver may be tuned to the first network. The transmitter may also transmit to the first network. The receiver may tune away to the second network for a tune-away period. The transmitter may transmit to the first network during the tune-away period. A determination may be made whether the transmitter and the receiver will cause interference during the tune-away period. Transmissions may be paused from the transmitter in response to determining that the transmitter and the receiver will cause interference during the tune-away period.

Abstract: Various embodiments include methods implemented on a mobile communication device for sharing network information among subscriptions when a first subscription is in a voice call and a second subscription is in an idle mode. The methods may include determining whether the first subscription and the second subscription share a network operator and are camped on a same base station. If so, the first subscription may receive network information from the base station and store the network information in a shared memory of the mobile communication device that can be accessed by the second subscription. The second subscription may then perform some idle mode operations using the network information stored in the shared memory.
