摘要： A system and method are provided for using frequency domain spreading to generate real signals in the time domain. The method supplies a first complex frequency domain symbol (α) and a second complex frequency domain symbol (αi), and maps (α+jαi) onto a subcarrier (+f). Further, (α−jαi)* is mapped onto a mirror subcarrier (−f). The mappings are converted into a complex time domain symbol carrying α and jαi in a single inverse fast Fourier transformation (IFFT). The real component of the complex time domain symbol (α) is initially supplied, and subsequently supplied is an imaginary component of the complex time domain symbol (αi). The real symbol component (α) is supplied by carrying α on the subcarrier (+f), and carrying (α)* on the mirror subcarrier (−f). The imaginary symbol component αi is supplied by carrying αi on the subcarrier (+f), and carrying (αi)* on the mirror subcarrier (−f).

摘要： A method and apparatus for generating and use of a position location reference signal that allows a receiver to receive position location signals from relatively weak signal generators when in the presence of a strong signal source. The position location reference signals from multiple sources can be synchronized to occur within a scheduled time slot of a time division multiplexed communication system. During the scheduled time slot, each signal source can configure a transmission that includes a media access control address that corresponds to a value reserved for position location signals. Each signal source also configures the transmission to include a position location reference signal that corresponds to the signal source. The position location signals from each of the signal sources is positioned to occur at a time within the data portion of the scheduled time slot that no neighboring signal source transmits its corresponding position location signal.

摘要： In general, techniques are described for preparing video data in accordance with a wireless display protocol. For example, a portable device comprising a module to store video data, a wireless display host module and a wireless interface may implement the techniques of this disclosure. The wireless display host module determines one or more display parameters of a three-dimensional (3D) display device external from the portable device and prepares the video data to generate 3D video data based on the determined display parameters. The wireless interface then wirelessly transmits the 3D video data to the external 3D display device. In this way, a portable device implements the techniques to prepare video data in accordance with a wireless display protocol.

摘要： In a generic Media Access Control (MAC) protocol, the retransmission of a dropped MAC frame is independent of the payload. Methods, systems, and computer products defining a mechanism of retransmission of one or more frames based on content of the payload are provided. The system identifies the content as text or video and retransmits if the content is text. The one or more frames may be retransmitted using a specific retransmission scheme. The retransmission is checked again to determine if it is was dropped, and transmitted again if it was dropped.

摘要： An orthogonal frequency division multiplex (OFDM) transmitter may adaptively load each sub-carrier, buffering less than an OFDM frame in order to reduce hardware requirements and latency. The transmitter may use feedback information from the receiver regarding the quality of the sub-carriers. In addition, combining repetition and puncturing to achieve a desired date rate per class further reduces hardware by simplifying or even eliminating an interleaver. Additional mitigation and even performance enhancement techniques are incorporated to address inter-class boundaries within an OFDM frame, such as introducing transition classes. Channel state information may be reported in various formats including full bitmap, changed subchannels, and reported bad subchannels.

摘要： A method is provided for reducing the search space of an acquiring ultra wideband (UWB) device seeking to join an UWB communication system, such as a Multi-band orthogonal frequency divisional multiplexing (OFDM) UWB system, by providing wireless network information, such as the hopping pattern or Time-Frequency Code (TFC), timing and frequency information to the acquiring UWB device. The wireless network information is provided using a short range wireless module such as Bluetooth that may coexist with a UWB device. For example, an assisting UWB device, via a short range Bluetooth device module, may convey initial synchronization information, to the acquiring UWB device that also may have a coexisting UWB module. By knowing the TFC, timing and frequency information the acquiring UWB device may know the approximate beginning of the superframes of the UWB devices in the UWB communication system which may help reduce power consumption and probability of false alarm.

摘要： In embodiments, a one-to-one association is established between a client and a host in a wireless network, such as a wireless local area network or a wireless personal communication network. The client may be a display device. The host may be a cellular telephone. Active association corresponds to the host exclusively using a shared resource of the client. When the association is solid, requests from other hosts to establish an active association are denied. When the association is fragile, such requests are granted. In the case of a semi-solid association, a request from another host to establish an active association causes the client to generate a query to the host currently owning the active association. If the host currently owning the association grants a release, a new active association is established between the requesting host and the client. Otherwise, the request from the other host is denied.

摘要： A novel power conservation scheme is provided for conserving power in client terminals by using a proxy server. The client terminal, having a low-power communication interface and a high-power communication interface, may power down its high-power communication interface, to conserve power. Prior to shutting off its high-power communication interface, the client terminal may assign a host terminal to act as a proxy for the client terminal. The host terminal monitors the paging channels for the client terminal via a high-power communication interface. If the host terminal detects a paging message for the client terminal, it forwards at least a portion of the paging message to the client terminal via a low-power communication interface. Upon receipt of the paging message from the host terminal via its low-power communication interface, the client terminal may power up its high-power communication interface and directly respond to an access terminal that initiated the paging message.
