Abstract: Apparatus and methods to support multiple subscriber identities in a wireless communication device are disclosed. A representative method includes the wireless communication device communicating with a first wireless network via a first wireless cellular protocol software stack for a first subscriber identity provided by a first subscriber identity module; communicating with a second wireless network via a second wireless cellular protocol software stack for a second subscriber identity provided by a second subscriber identity module; and sharing mobility management tasks between the first and second wireless cellular protocol software stacks when the first and second subscriber identity modules are each associated with the same wireless network provider either as a serving carrier or as a roaming carrier. Mobility management tasks that are shared include one or more of paging channel monitoring, measuring a serving cell and/or neighbor cells, evaluating cell reselection and handover options, and reading broadcast channels.

Abstract: This disclosure relates to performing cellular communication using a power efficient downlink control information framework. A wireless device and a cellular base station may exchange configuration information indicating that the cellular base station and the wireless device support a sleep downlink control information (sDCI) format. An sDCI configuration according to the sDCI format may be negotiated, including selecting at least one sDCI configuration parameter based at least in part on an application type currently associated with cellular communication between the cellular base station and the wireless device. Downlink control information may be provided during one or more subframes in accordance with the sDCI configuration. One or more subframes for which no downlink control information will be provided to the wireless device may be determined based at least in part on the sDCI configuration.

Abstract: Apparatus and methods to reuse wireless circuitry to communicate with multiple wireless networks to support multiple subscriber identities in a wireless communication device are disclosed. A representative method includes receiving signaling messages for a second subscriber identity from a second wireless network while connected to a first wireless network for a first subscriber identity. A portion of radio frequency wireless circuitry is reconfigured to communicate with the second wireless network to establish a signaling channel and respond to signaling messages received from the second wireless network. The portion of radio frequency wireless circuitry is reconfigured between the first and second wireless networks to maintain a connection with the first wireless network while also receiving from the second wireless network limited information that can be provided to a user. Representative information includes an indication of an originator of a mobile terminated connection request and short message service data.

Abstract: Apparatuses, systems, and methods for user equipment (UE) devices to perform more efficient frequency scans for potential base stations. According to techniques described herein, the UE may, in response to detecting that UE does not have cellular service, perform a full band scan to search for a last registered public land mobile network (PLMN) and the full band scan may discover one or more cells not associated with the last registered PLMN. The UE may populate a database with one or more parameters associated with the one or more cells and in response to not finding the last registered PLMN, perform a targeted scan limited to a set of PLMNs found during the full band scan. In some embodiments, each PLMN in the set of PLMNs may be comprised in a roaming PLMN list for an operator.

Abstract: An accessory wireless device partakes in a data session with a remote device. The data session may be a voice call or other service. To preserve the battery power of the accessory wireless device, the accessory wireless device opportunistically offloads medium-to-long range radio transmission and reception tasks to the companion wireless device while maintaining call continuity. The accessory wireless device and the companion wireless device communicate through a local connection. In one embodiment, the accessory wireless device pushes a wireless wide area network (WWAN) connection to the companion device by sharing selected security and network information with the companion wireless device. When the accessory device and/or the companion device determine that the local connection may not be sustainable, the accessory device pulls the WWAN connection of the companion device back to itself.

Abstract: In some embodiments, a user equipment device (UE) implements improved communication methods which include radio resource time multiplexing, dynamic sub-frame allocation, and UE transmit duty cycle control. In some embodiments, the UE may communicate with base stations using radio frames that include multiple sub-frames, transmit information regarding allocation of a portion of the sub-frames of a respective radio frame for each of a plurality of the radio frames, and transmit and receive data using allocated sub-frames and not using unallocated sub-frames. In some embodiments, the UE may operate according to a sub-frame allocation based on its current power state. The UE may transmit information to the base station and receive the sub-frame allocation based on at least the information. In some embodiments, the UE may switch transmit duty cycles based on an occurrence of a condition at the UE. The UE may inform the network of the switch.

Abstract: A station that generates data packets to be transmitted by the station such that the data packets spend a minimum amount of time in a buffer prior to transmission. The method includes receiving a specification for a connected discontinuous reception (C-DRX) cycle, the specification indicating when a plurality of onDurations of the C-DRX cycle occurs, the onDurations having a predetermined interval therebetween, receiving data at a known time relative to the C-DRX cycle, determining a modification to a conversion process that converts the data to data packets such that the data packets are stored in a buffer at a subframe immediately preceding one of the onDurations subsequent to the known time, performing the conversion process based upon the modification and storing the data packets at the subframe immediately preceding the one of the onDurations. In one embodiment, the data is raw audio data and the data packets are audio packets.
