    摘要: A method and apparatus for acquiring timing signals for use in a positioning receiver using timing assistance provided by a wireless communications system, such as cellular telephone system. A mobile terminal equipped with a positioning receiver operates in a wireless communications system having control channels and at least one traffic channel unsynchronized to the control channels. The mobile terminal camps on a first control channel in a first cell having a first time base associated therewith. While camped on the control channel, the mobile terminal establishes a local clock reference, internal to the mobile terminal, capable of tracking the first time base. The mobile terminal then operates on a first traffic channel that is unsynchronized to the first control channel and notes the difference in time bases between the control channel and the traffic channel. Either while camped on the control channel or while operating on the traffic channel, the mobile terminal receives TDMA-to-GPS relationship data, which is a measure of the offset between system time for the wireless communications system as expressed on particular control channel (“TDMA time”) and the system time for the GPS system (“GPS time”). Thereafter, an accurate estimate of the GPS time is calculated in the mobile terminal based on the local clock reference and the TDMA-to-GPS relationship data. In some aspects, the local clock reference is updated based on the first traffic channel so as to minimize errors arising from timing drift.

    摘要: An event-triggered pairing mechanism allows pairing wireless devices having short range interfaces (e.g., Bluetooth devices) by bumping the wireless devices together. A wireless device being paired with a connecting device detects a bump event; exchanges time information about the bump event with the connecting device; authenticates the connecting device based on the exchanged time information; and allows exchange of user data with the connecting device based on verification of the exchanged time information. Once the devices are paired, user content can be securely exchanged between the devices.

    摘要: Methods and apparatus for processing received signals in a multi-carrier system are disclosed. An exemplary method includes estimating one or more first propagation channel coefficients based on a training sequence in each of one or more first slots received over a first radio channel, equalizing signal samples from one or more second slots received over a second radio channel immediately frequency-adjacent to the first radio channel, using the first propagation channel coefficients, and demodulating user data bits from the equalized signal samples. In some embodiments, the training sequence is located at a fixed position in each of the one or more first slots and user data bits are demodulated from a directly corresponding position in each of the second slots. Improved data rates are thus achieved by constraining radio carriers in a multi-carrier system to frequency-adjacent channels and eliminating training symbols from one of the signals.

    摘要: The wireless receiver of the present invention accommodates dual-carrier Evolved EDGE without significantly impacting existing receiver architectures. The inventive receiver comprises a shared local oscillator and two image-rejecting downconverters. The local oscillator generates a local oscillator frequency between two carrier frequencies of adjacent radio channels. The receiver receives a signal in each of the adjacent radio channels. In a dual-carrier mode, a first image-rejecting downconverter uses the local oscillator frequency to downconvert a first signal received in the first radio channel while rejecting a second signal received in the second radio channel. A second image-rejecting downconverter uses the local oscillator frequency to downconvert the second signal while rejecting the first signal. In a diversity mode, the first and second image-rejecting downconverters use the local oscillator frequency to downconvert the signal received in one of the radio channels while rejecting the signal received in the other radio channel.

    摘要: A method for scheduling another time for a communication session when a called party is presently unable or unwilling to accept an incoming call. A first user's communications device receives a request for a communication session from a second user's communications device. Upon failure to accept the request, a server automatically forms a calendar data object, such as in response to receipt of a scheduling trigger message from the first communications device that includes an indication of the failure to accept and an identifier of the second user. The calendar data object includes scheduling information indicating, explicitly and/or implicitly, future time(s) when the first user is available. The calendar data object is sent to either one of the devices, and a time is selected. The server then notifies the other device of the selected time. Corresponding devices are also described.

    摘要: A method and apparatus for selectively rendering audio-video information to user output devices based on the current configuration of the wireless communication device is described herein. The audio-video information comprises an audio component, a video component, and a metadata component. The wireless communication device outputs the video component to an internal display and the audio component to a speaker when the wireless communication device operates in an open configuration. When in the closed configuration, the wireless communication device stops outputting the video component to the internal display. Further, the closed wireless communication device continues to output the audio component to the speaker while outputting the metadata to an external display.
