摘要： Motion status states reported by an advanced motion detection process or other means of obtaining a movement state of Stationary or Non-Stationary from filtered accelerometer data are utilized to reacquire service during Out of Service scenarios. Both movement states operate in three power phases: aggressive scanning or normal power mode, slow scanning or moderate power mode, and deep sleep or power saving mode. The scanning rate, power mode, scanning period and/or channel list depend upon the movement state and power phase. Motion information obtained from an advanced motion detection process provides substantial improvements in service reacquisition performance and power consumption in stationary Out of Service scenarios. When compared to traditional service reacquisition scanning routines, the reductions in average current can be achieved of: at a 5-minute OOS mark, ~45% reduction, at a 15-minute OOS mark, ~60% reduction and at a 6-hour OOS mark, ~50% reduction.
摘要翻译：利用先进的运动检测过程或从过滤的加速度计数据获得静止或非静止的运动状态的其他手段报告的运动状态状态被用于在停用场景期间重新获取服务。两种移动状态都有三个功率阶段：积极扫描或正常功耗模式，慢速扫描或中等功耗模式以及深度睡眠或省电模式。扫描速率，功率模式，扫描周期和/或频道列表取决于移动状态和功率相位。从先进的运动检测过程中获得的运动信息提供了服务重新捕获性能和固定停止服务情况下的功耗的实质性改进。与传统服务重新捕获扫描例程相比，平均电流的降低可以达到：在OOS标记5分钟，减少约45％，OOS标记15分钟，减少约60％以及6小时 OOS标志，减少〜50％。

摘要： Disclosed are methods and apparatus for detecting mismatch of ciphering parameters, such as Count-C, in a wireless device and recovery therefrom. The methods and apparatus for detection include examining a predefined ciphered field, such as a Length Indicator field, in one or more received Radio Link Control (RLC) Protocol Data Units (PDUs). Next, a determination of when the field is invalid over a predetermined sample number of PDUs is performed. Mismatch of ciphering parameters can then be determined when a predetermined number of samples of the field detected as invalid exceed a predetermined threshold. Additionally, recovery of PDUs after mismatch detections is disclosed using a range of Hyper-Frame Numbers (HFNs) to decipher buffered PDUs, and then check which of the HFNs eliminate the parameter mismatch by again determining if parameter mismatch occurs using the methods and apparatus for detection.

摘要： An improved method and apparatus for Mobile Transmit Diversity (MTD), or Uplink Transmit Diversity (ULTD) is disclosed. The mobile device either selects the best antenna at any given time, or transmits from both antennas using the best beam forming phase without feedback from the base station on which antenna to transmit from or which phase to use if using two antennas. Essentially operating in Open Loop MTD, a Hybrid Phase Sweeping algorithm requires testing of a fraction of phase hypotheses resulting in improved base station performance and higher data rates for the user. One among the set of transmission test phase hypotheses (for example: 0,90,180 and 270 degrees) is selected using a turn direction (left or right). The uplink transmission quality for the selected test phase hypotheses during a test period is compared with the uplink transmission quality during steady state. The current phase is changed to the test phase if the first quality value is better.

摘要： A channel impulse response (CIR) estimate associated with a communication channel may be processed by determining coefficient values that respectively correspond to taps of the CIR estimate, and multiplying the taps by the respectively corresponding coefficient values. The coefficient values are determined according to a soft decision technique. The resulting modified CIR estimate is used to demodulate a communication signal received via the communication channel.

摘要： Disclosed are apparatus and methods for use in a USB device with multiple processors, allowing shared USB connectivity in the device. The disclosed apparatus and methods allow selective coupling of a first processor to a USB port of the device or to a USB hub operable to route a plurality of USB connections including connection of a second processor to the port. Providing selective coupling of the processors to the port by switching the coupling of the first processor and selectively powering the hub on and off for selective coupling of the second processor, thereby selectively enabling tethered networking such as wireless networking, affords increased power savings in the device. Furthermore, default coupling of the first processor to the port allows for USB battery charger detection, or direct connectivity to USB peripheral devices, as well as providing programming capability via the default coupling of the port to the first processor.

摘要： Methods and apparatus for signal scanning and acquisition for multiple-air-interface devices are discussed. In particular, scanning of a location for signals from one or more local service providers is carried out, wherein scanning is operable to detect signals based on at least a first air interface and a second air interface, such as CDMA and UMTS, respectively. A list of local service providers detected from the scanning is assembled to allow a user to select a connection to at a local service provider from the list. Thus, a user is afforded the ability to see all service provider signals in the location, for all bands and air-interfaces supported by the modem on a user's multiple-air-interface device. The user may therefore acquire connection more easily without having any prior knowledge about the area or its service providers, and regardless of the type of air interface originating the local signals.
摘要翻译：讨论了用于多空气接口设备信号扫描和采集的方法和装置。特别地，执行对来自一个或多个本地服务提供商的信号的位置的扫描，其中扫描可操作以分别基于至少第一空中接口和第二空中接口（例如CDMA和UMTS）来检测信号。组装从扫描检测到的本地服务提供商的列表，以允许用户从列表中选择到本地服务提供商的连接。因此，向用户提供在用户的多空接口设备上为调制解调器支持的所有频带和空中接口的位置查看所有服务提供商信号的能力。因此，用户可以更容易地获取连接，而不需要关于区域或其服务提供商的任何先前知识，并且不管发起本地信号的空中接口的类型如何。
