摘要： In general, this disclosure describes techniques for exchanging information between a plurality of encoder modules and a multiplex module to combine segments of data from the encoder modules with an improved overall quality. In particular, the encoder modules associate their respective segments of data with quality and rate information and send at least the quality and rate information associated with the segments of data to the multiplex module. The multiplex module analyzes the quality and rate information to determine whether the segments of data that encoder modules desire to include in the current superframe fit within the available bandwidth of a transmission channel. If the multiplex module determines the plurality of segments of data do not fit within the available bandwidth, the multiplex module selects one or more of the segments to be resized based on the quality and rate information received from the encoder modules.

摘要： Aspects of de-registering a multicast group member from a multicast group within a wireless communications network are disclosed. An access terminal sends a first multicast registration message to an access network, with the first multicast registration message identifying a first set of multicast groups. The access network receives the first multicast registration message and registers the access terminal for each of the first set of multicast groups. The access terminal sends a second multicast registration message, the second multicast registration message omitting at least one multicast group from among the first set of multicast groups, the second multicast registration message being sent to request de-registration, for the access terminal, from at least one multicast group. The access network receives the second multicast registration message and interprets the second multicast registration message as a request to de-register the access terminal from the omitted at least one multicast group.

摘要： A method and device for managing a reference oscillator within a wireless device is presented. The method includes selecting reference oscillator parameters associated with the lowest reference oscillator error, where the selection is based upon reference oscillator parameters derived using different technologies within a wireless device, acquiring a satellite based upon the selected reference parameters, determining the quality of the satellite-based position fix, and updating the reference oscillator parameters based upon the quality of the satellite-based position fix. The wireless device includes a wireless communications system, a satellite positioning system (SPS) receiver, a reference oscillator connected to the wireless communications system and SPS receiver, and a mobile controller connected to the reference oscillator, SPS, and wireless communications system, and a memory connected to the mobile controller, where the memory stores a reference oscillator parameter table and instructions causing the mobile controller to execute the aforementioned method.

摘要： A method for processing a multichannel audio signal may be configured to control the amplitude of one channel of the signal relative to another based on the levels of the two channels. One such example uses a bias factor, which is based on a standard orientation of an audio sensing device relative to a directional acoustic information source, for amplitude control of information segments of the signal.

摘要： A wireless communication device that has one or more applications resident on a computer platform, a wireless communication interface, a display, and a user interface that, at least, appears on the display and through which a user of the wireless communication device interacts with the computer platform. The display is configured to be selectively controlled by the specific user interfaces of one or more applications resident on the computer platform, and the one or more applications and/or an arbiter that is resident on the computer platform will determine which user interface of the one or more applications resident on the computer platform controls the display based upon a predetermined criteria when the user interfaces compete for control of the display.

摘要： Backward compatibility may require the use of fields or other indicators that are interpreted by new nodes or stations in a system in a manner different from the way legacy nodes interpret those same fields. In some circumstances, these indicators may be used to 'spoof' legacy nodes to behave in certain ways, to allow a next generation protocol to be performed without interference from those legacy nodes. While this practice is may increase communication effectiveness, spoofing may lead to inefficient operation of legacy nodes. Legacy nodes may detect spoofing, including detecting field settings in a legacy portion of a transmitted message, or detecting phase shifts in a message. Once spoofing is detected, a variety of steps may be taken, including determining the duration of the next generation message, entering a low power state for the duration, communicating on alternate channels for the duration, modifying legacy backoff procedures, and others.
摘要翻译：向后兼容性可能需要使用不同于传统节点解释这些相同字段的方式在系统中由新节点或电台解释的字段或其他指示符。在某些情况下，这些指示符可以用于“欺骗”传统节点以某些方式表现，以允许执行下一代协议而不受这些传统节点的干扰。虽然这种做法可能会增加通信效率，但是欺骗可能导致传统节点的低效运行。传统节点可以检测欺骗，包括检测传输消息的传统部分中的字段设置，或检测消息中的相移。一旦检测到欺骗，可以采取各种步骤，包括确定下一代消息的持续时间，持续持续时间内进入低功率状态，在持续时间内在备用信道上进行通信，修改遗留回退过程等。

摘要： Techniques for performing detection and decoding at a receiver are described. In one scheme, the receiver obtains R received symbol streams for M data streams transmitted by a transmitter, performs receiver spatial processing on the received symbols to obtain detected symbols, performs log-likelihood ratio (LLR) computation independently for each of D best data streams, and performs LLR computation jointly for the M - D remaining data streams, where M > D ≥ 1 and M > 1. The D best data streams may be selected based on SNR and/or other criteria. In another scheme, the receiver performs LLR computation independently for each of the D best data streams, performs LLR computation jointly for the M - D remaining data streams, and reduces the number of hypotheses to consider for the joint LLR computation by performing a search for candidate hypotheses using list sphere detection, Markov chain Monte Carlo, or some other search technique.
