    Abstract: Embodiments of a wireless station to operate as a per-symbol relay device and method for retransmission of symbols between client devices and a master device using millimeter-wave links is generally disclosed herein. In some embodiments, the relay device may receive one or more of independent symbol streams from the master device. Each independent symbol stream may comprise packets that include groups of one or more symbols. Each group within a packet may be destined for a different one of the client devices. The relay device may separately decode each symbol or group of symbols to generate an independent stream of symbols for retransmission to the client devices using beamforming. The relay device may be arranged to receive, decode, and retransmit each symbol or group of symbols within a delay that is bounded by the number of symbols in the group.

    Abstract: Embodiments of a wireless device and method for transmitting a packet comprising one or more orthogonal frequency division multiplexed (OFDM) transmission symbols are generally described herein. In some embodiments, the wireless device may be configured to map data to active tones and map zeroes to nulled tones of a set of OFDM tones to generate an OFDM symbol comprising both the active and the nulled tones. The number of active and nulled tones may be based on a nulling factor. The OFDM symbol may be down-clocked to generate an OFDM transmission symbol for transmission over a reduced transmission bandwidth. Accordingly, low power may be used for very low data rate transmissions, which may be suitable for sensor devices.

    Abstract translation: 本文通常描述用于发送包括一个或多个正交频分复用（OFDM）传输符号的分组的无线设备和方法的实施例。 在一些实施例中，无线设备可以被配置为将数据映射到活动音调并且将零映射到一组OFDM音调的零位音，以生成包括有效和无效音调的OFDM符号。 有效和无效音调的数量可以基于归零因子。 OFDM符号可以被降频以产生用于在降低的传输带宽上传输的OFDM传输符号。 因此，低功率可用于非常低的数据速率传输，这可能适用于传感器设备。

    Abstract: Pilot logic may determine based upon channel and phase information how to process pilot tones that shift locations every N symbols in an orthogonal frequency division multiplexing (OFDM) packet transmission. Pilot logic may determine a signal-to-noise ratio (SNR) for the channel to determine how to process the shifting pilot tones. Pilot logic may also determine channel and phase information updates such as channel state information and phase correction information from pilot tones. In situations of high SNR, logic may use channel estimates and phase rotations that are obtained from locations of the pilot tones for phase tracking and updating the equalizer. In situations of low SNR, logic may use the phase rotations for phase tracking and not update the equalizer during the OFDM transmission. Logic may also determine the presence or absence of a Doppler effect on the transmission and transmit a selection for N to an access point in response.

    Abstract: Embodiments may comprise an orthogonal frequency division multiplexing (OFDM) system operating in the 1 GHz and lower frequency bands. In many embodiments, the physical layer logic may implement orthogonal frequency division multiplexing symbols encoded with 32 sub-carriers such as twenty data sub-carriers, four pilot sub-carriers, seven guard sub-carriers, and one direct current (DC) sub-carrier. Many embodiments may transform the orthogonal frequency division multiplexing symbols between frequency and time domains with a 32-point, fast Fourier transform or inverse fast Fourier transform. Some embodiments may up-convert and transmit a communication signal with the orthogonal frequency division multiplexing symbols at one megahertz. Further embodiments may receive and detect communications signal with the orthogonal frequency division multiplexing symbols at one megahertz.
