    摘要： 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 repetition logic to repeat portions of the data streams to increase the ability of a receiving device to detect and decode the data streams. In some embodiments, the repetition logic may comprise a preamble repeater to repeat the training and/or signal fields. In further embodiments, the repetition logic may comprise a payload repeater to repeat the payload one or more times. Other embodiments comprise a receiving device comprising a correlator to correlate the repeated preamble symbols to detect a communication from a transmitting device. The receiving device may also comprise correction logic to correct data streams from the communications signal based upon repetitions of the payload in the data streams.

    摘要： Logic may comprise a single phase tracking implementation for all bandwidths of operation and the logic may adaptively change pre-defined and stored track parameters if the receiving packet is 1 MHz bandwidth. Logic may detect a packet and long training fields before performing a 1 MHz classification. Logic may auto-detect 1 MHz bandwidth transmissions by a property of the long training field sequences. Logic may auto-detect 1 MHz bandwidth transmissions by detecting a Binary Phase Shift Keying (BPSK) modulated first signal field symbol rather than the Quadrature Binary Phase Shift Keying (QBPSK) associated with the 2 MHz or greater bandwidth transmissions. Logic may perform an algorithm to determine an estimated phase correction value for a given orthogonal frequency division multiplexing symbol and several embodiments integrate this value with an intercept multiplier that may be 0.2 for 1 MHz transmissions and, e.g., 0.5 for 2 MHz or greater bandwidth communication.

    摘要： Examples are disclosed for updating a wireless communication channel estimation. In some examples, a packet may be transmitted or received via a communication channel, the packet having one or more pilot signals that may shift between subcarrier frequencies based on a predetermined first variable associated with a first time duration. A second variable associated with a second time duration may be determined by the receiver of the data packet. The second variable may enable a receiver of the data packet to decide how many pilot signals may be used to update an initial channel estimation for the communication channel. Other examples are described and claimed.

    摘要： Pilot logic may determine channel information updates such as channel state information and phase correction information from pilot tones that do not travel close to the DC tone or the band edge tones. Logic may skip channel updates and phase tracking from pilot tones that have traveled close to the DC tone or the edge tones. In other words, logic may process the shifting pilot tones except for the pilot tones located adjacent to the DC tone and the edge tones. Logic may use channel estimates and phase rotations that are obtained from previous locations of the pilot tones instead of pilot tones that are adjacent to the DC tone or the edge tones. Logic may access memory to store the channel information such as the phase correction information previously obtained and the channel state information previously obtained and derived from processing pilot tones at locations adjacent to the symbol indices next to the DC tone and the edge tones.

    摘要： Methods, apparatuses, and computer readable media for signaling high-efficiency packet formats using a legacy portion of the preamble in wireless local-area networks are disclosed. A high-efficiency (HE) wireless local area network (HEW) device including circuitry is disclosed. The circuitry may be configured to generate a HE packet comprising a legacy signal field (L-SIG) followed by one or more HE signal fields, and configure the L-SIG to signal to a second HEW device either a first packet format of the HE packet or a second packet format of the HE packet, where a length of the L-SIG modulo 3 is used to signal the first packet format or the second packet format. The circuitry may be configured to generate a duplicated L-SIG field with a polarity difference to indicate a third packet configuration of the HE packet or a fourth packet configuration of the HE packet.

    摘要： Wireless devices, methods, and computer readable media for synchronization in a wireless local-area network. A method on a wireless communication device may include tuning to a first subchannel based on a schedule received from an access point (AP) the schedule to indicate that the HEW device is assigned to the first subchannel. The method may further include determining a target beacon receive time and tuning to a second subchannel to receive the target beacon at the target beacon receive time. The method may further include receiving the target beacon on the second subchannel and tuning back to the first subchannel. A method on an AP for synchronization may include transmitting information that indicates a target beacon receive time on a subchannel. The method may include not transmitting to a wireless communication device operating on a second subchannel for a period of time before the target beacon receive time, and transmitting a target beacon on a first subchannel at the target beacon receive time.
