    摘要： The disclosure generally relates to a shortened training field preamble structure for high-efficiency Wi-Fi environments. In one embodiment, the disclosure relates to a communication system having a transmitter transmitting a Master-Sync packet received by stationary and mobile receivers. The Master-Sync packet contains information for communicating in a HEW environment. Upon receipt each receiver decodes the Master-Sync packet to (i) estimate a frequency offset and/or an automatic gain control (AGC) setting; (ii) select a transmission frequency consistent with the frequency offset; and/or (iii) determine a new transmission power consistent with the AGC; (iv) tune to a new frequency offset and gain control setting to receive subsequent packets from the transmitter.

    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： An approach is provided for defining a 1MHz preamble of a packet. The approach involves determining a preamble sequence of a packet, the preamble sequence having a determinable length. The approach also involves causing, at least in part, the preamble sequence to be divided into a predetermined number of blocks. The approach further involves causing, at least in part, a mathematical operation and a summation over the predetermined number of blocks and a corresponding number of received blocks. The approach also involves causing, at least in part, the summation to be maximized to determine the preamble sequence corresponds to one of a first bandwidth or a second bandwidth, the second bandwidth being greater than the first bandwidth, to determine a type of the packet.

    摘要： Systems, devices and methods for updating link adaptations in multi-carrier modulated signals between an access point (AP) and a wireless local area network (WLAN) station (STA) include (are configured for) periodically transmitting a channel sounding signal from the AP. The STA receives each unsolicited channel sounding signal and evaluates the current channel conditions between the AP and STA. The AP adjusts a rate of transmission of the channel sounding signals in accordance with the channel coherence time so that the channel estimates performed by the STA will be valid within the time varying characteristics of the channel. Depending on the length of the coherence time for network environment, the channel sounding signals may be AP beacons, low overhead signal fragments with no payload, or a combination of both.

    摘要： Logic may reduce overhead in communications that include pilot tones in symbols by establishing a predefined pattern of subcarriers on which the pilot tones are transmitted and including the pilot tones in L out of every N symbols in the communications. Logic may implement communications in accordance with the predefined pattern of subcarriers by inserting N minus L symbols between symbols with pilot tones on each of the subcarriers of the predefined pattern of subcarriers or by inserting tones other than pilot tones on pilot subcarriers in N minus L out of every N symbols. Logic may determine channel state information along with carrier frequency and phase tracking information from pilot tones in the symbols. And logic may determine channel state information for symbols that do not include pilot tones by calculating channel estimates based upon channel estimates of adjacent subcarriers and/or by previous channel estimates of the pilot subcarriers.
