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.

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.

An exemplary apparatus includes a receiver to wirelessly receive a first packet comprising first and second shifting pilot signals amidst first data symbols transmitted via multiple subcarriers in symbol sets; a transmitter to wireless transmit a second packet; and logic to track a phase shift using the first and second shifting pilot signals, to configure the receiver to compensate for the shift in phase, to refrain from using reception of the first and second shifting pilot signals to update an initial channel estimate derived from a preamble of the first packet, and to transmit third and fourth shifting pilot signals amidst second data symbols of the second packet.

摘要： Embodiments may comprise logic such as hardware and/or code to reduce power consumption by, e.g., a device such as a station or relay by implementing prediction logic to decode and determine whether a communication affects the operation of the device. Some embodiments may comprise logic to receive at least a portion of a header of a frame from a physical layer and begin to decode the portion of the header of the frame without first checking the correctness of the value in the frame check sequence field. In many embodiments, prediction logic may determine whether the frame could have an impact on the operation of the device. For circumstances in which the prediction logic determines that the frame will not have an impact, the MAC logic may terminate processing, receipt, and decoding of the frame and enter the device into a low power consumption state.
