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.

Techniques and apparatuses for tune-away management

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.

Subscriptions scheduling in multi-subscription devices

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.

Receiver-only tune-away

Various embodiments enable recovering from an out-of-service state in a wireless device. A processor may perform scans of a first acquisition database to acquire a first renewed service connection for a first subscriber identification module (SIM). The scans include first and second searches for first and second channels identified in first and second technology lists, respectively, from the first 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 first and second radio access technologies. A currently used channel of a second SIM acquired service is first on the first technology list. 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.

Out-of-service recovery for a multi-SIM wireless device

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.

Using client-specific RGS to improve performance on multi-SIM and multi-RAT devices

Various embodiments include methods implemented on a mobile communication device for sharing network information among subscriptions when a first subscription is in a data communication session 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.

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.

Systems, methods, apparatuses, and media are provided for downlink power control. Embodiments include determination that a portion of a frame to be transmitted in a downlink from a base station to a user equipment (UE) may be lost by the UE. Embodiments further include determination that a portion of the frame will be received by the UE. Embodiments further include causing a transmit power of the base station to be increased for the portion of the frame that will be received.

Downlink power control adjustment based on lost frame portion determination

Methods and apparatus of controlling user equipment transmit power in a wireless communication system include communicating with a first base station and a second base station. Further, the methods and apparatus include establishing a high speed channel with one of the first base station or the second base station, wherein the one of the first base station or the second base station defines a high speed serving cell and a remaining one of the first base station or the second base station defines a non-high speed cell. Additionally, the methods and apparatus include ignoring a transmit power control command from the non-high speed cell when a high speed power control state applies to controlling a transmit power level.

Apparatus and methods of HSPA transmit power control

Various embodiments include methods, systems, and devices for tuning away a mobile device's receiver without retuning the mobile device's transmitter, thereby allowing the mobile device to monitor multiple networks with a single radio frequency (RF) chain while avoiding the problems often associated with tune-away methods, such as loss of throughput, loss of tracking or synchronization, delays in acknowledgments, delays in rate control or channel quality control feedback, etc. The transmitter may remain tuned to a first network while the receiver may be separately tuned to one or more other networks. In various embodiments, the separately tuned receiver may monitor for paging signals on one or more networks while the transmitter remains tuned to the first network and transmits data or control signals.

Methods and apparatus of monitoring cells in a wireless communication system may include determining existence of a condition for performing a cell search on a frequency. In addition, the methods and apparatus may include calculating an undetected energy-related value for a hypothetical undetected cell based on a measured energy-related value of each detected cell on the frequency in response to determining the condition for performing the cell search. The methods and apparatus may further include determining whether to perform the cell search based on the undetected energy-related value and a reselection criteria.

Methods, systems and devices are provided for controlling a communication device. Embodiments include receiving, through the transceiver, a voice call from a first network subscription associated with a first SIM of the communication device. The voice call may interrupt an active data services session through the transceiver with a second network subscription associated with a second SIM of the communication device. Also, embodiments include establishing an active voice communication connection for the voice call on the transceiver with the first network subscription. Additionally, reestablishing the active data services session through the transceiver with the first network subscription while maintaining the active voice communication connection for the voice call with the first network subscription.

Simultaneous voice and data for Dual-SIM-Dual-Standby (DSDS) wireless device

The various embodiments include methods for managing how a MSMS communication device that is accessing an arbitrary combination of multiple telephony networks processes paging collisions. The embodiment methods promote improving a subscription's page blocking rate by causing a MSMS communication device to implement a retransmission remedial action for a blocked subscription. In the various embodiments, the MSMS communication device may implement the retransmission remedial action by increasing a blocked subscription's priority during a subsequent retransmission interval to increase the likelihood that the blocked subscription will receive a repeated page message from its mobile network during this retransmission interval. In some embodiments, the blocked subscription's current priority may be based on the number of retransmission intervals that are presently occurring.

Multiple subscription resource access control
