Abstract: Methods, systems and apparatus for a user equipment to implement a dynamic discard timer. The user equipment may generate a packet for transmission and store the packet in a buffer of the user equipment. The user equipment may then generate a timeout value for a discard timer for the buffer, where the discard timer discards the packet from the buffer when the timeout value is reached. After a predetermined amount of time, the user equipment may determine whether the packet has been discarded from the buffer and, when it is determined that the packet has not been discarded from the buffer, update the timeout value.

Abstract: A mobile wireless device adapts receive diversity during discontinuous reception based on downlink signal quality, page indicators and page messages. When the downlink signal quality exceeds a pre-determined threshold, the mobile wireless device decodes a page indicator channel through an initial antenna, and otherwise, decodes a paging channel through the initial antenna without decoding the page indicator channel. The mobile wireless device switches to decoding the paging channel through an alternate antenna when a page indicator decodes as an erasure. When a paging message received through a single antenna decodes with an incorrect error checking code, the mobile wireless devices enables receive diversity through multiple antennas for subsequent decoding. The mobile wireless device switches between single antenna reception and multiple antenna reception based on tracking multiple consecutive error checking code failures and successes.

Abstract translation: 移动无线设备基于下行链路信号质量，页面指示符和寻呼消息来适应不连续接收期间的接收分集。 当下行链路信号质量超过预定阈值时，移动无线设备通过初始天线解码页面指示符信道，否则，通过初始天线对寻呼信道进行解码，而不对页面指示符信道进行解码。 当页面指示符被解码为擦除时，移动无线设备切换到通过替代天线解码寻呼信道。 当通过单个天线接收的寻呼消息用错误的错误校验码进行解码时，移动无线设备能够通过多个天线进行接收分集以用于后续解码。 基于跟踪多个连续的错误检查代码故障和成功，移动无线设备在单天线接收和多天线接收之间切换。

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: Methods and apparatus to reduce power consumption in user equipment (UE) that operates in a connected discontinuous reception (C-DRX) mode while in communication with wireless network are disclosed. A C-DRX warm-up period before the UE enters an on-duration is adjusted dynamically based on one or more factors including a time division duplex (TDD) uplink/downlink (UL/DL) subframe configuration, signal-to-noise ratio (SNR) values, and Doppler shift values. The C-DRX warm-up period is adapted based on the pattern of DL subframes in the UL/DL subframe configuration by including DL subframes that best contribute to channel estimation and adaptive tracking loops based on measured SNR and Doppler shift conditions. Favorable channel conditions, such as higher SNR and lower Doppler shift, can require fewer DL subframes and consequently shorter C-DRX warm-up periods. Higher Doppler shift values indicate more rapidly varying channel conditions and require DL subframes positioned closer to the start of the on-duration.

Abstract: A network reselection procedure, of a wireless communication device, that occurs following a network detachment event, such as a device sleep event or a device power savings mode event. The wireless communication device attempts to acquire a first wireless network to which the wireless communication device was most recently attached, immediately preceding the network detachment event. Then, in response to an unsuccessful acquisition of the first wireless network, the wireless communication device attempts an alternate network acquisition utilizing a Most Recently Used List (MRUL) that is stored at the wireless communication device and includes information about one or more frequency bands allocated to a primary service provider with which the wireless communication device is affiliated. After determining whether the alternate network acquisition attempt was successful, the wireless communication device attaches to a second network and stores information associated with the second network.
