摘要： Embodiments of a system and methods for distinguishing high-efficiency Wi-Fi (HEW) packets from legacy packets are generally described herein. In some embodiments, an access point may select a value for the length field of a legacy signal field (L-SIG) that is non-divisible by three for communicating with HEW stations and may select a value for the length field that is divisible by three for communicating with legacy stations. In some embodiments, the access point may select a phase rotation for application to the BPSK modulation of at least one of the first and second symbols of a subsequent signal field to distinguish a high-throughput (HT) PPDU, a very-high throughput (VHT) PPDU and an HEW PPDU.

摘要： Embodiments of a master station and method for communicating in a Wi-Fi network in accordance with a high-efficiency Wi-Fi (HEW) technique are generally described herein. In some embodiments, the master station is configured to communicate with scheduled stations using the antennas within a bandwidth comprising one or more 20 MHz Wi-Fi channels using a plurality of minimum orthogonal frequency division multiple access (OFDMA) bandwidth units during an OFDMA control period during which the master station has exclusive control of a wireless medium. Each minimum OFDMA bandwidth unit may comprise a predetermined number of subcarriers that do not include guard subcarriers of the channel wherein the guard subcarriers are provided at band edges of the bandwidth, the guard subcarriers being in addition to the subcarriers of each of the minimum OFDMA bandwidth units. In some embodiments, no guard subcarriers are provided between the minimum OFDMA bandwidth units within a 20 MHz channel.

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： 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.

摘要： Embodiments of the disclosure relate to operational association between communication devices in the presence of a link-budget imbalance between an upstream link and a downstream link at one of the communication devices. The association relies on a request for a narrowband resource block sent from the communication device having the link-budget imbalance to a remote communication device that can schedule and/or allocate the narrowband resource block. The request can be modulated according to an on-off keying modulation scheme or can be encoded according to a multi-repetition encoding scheme. In response to the narrowband resource block being allocated, an association request can be sent to the remote communication device in the narrowband resource block.

摘要： Generally, embodiments to enable, indicate and detect Short Interframe Space (SIFS) of different time durations, a short (or small) SIFS which is shorter in duration than a regular SIFS, are described herein. Embodiments may comprise logic such as hardware and/or code to signal a short SIFS or a regular SIFS by setting or clearing a bit of a management frame transmitted by a station to an access point during the network association process, or by setting or clearing a bit in the SIG field of the preamble of a data unit transmitted by an access point to an associated station. In some embodiments, a third party station is able to receive the data unit sent by the access point, and decode, e.g., the SIG field bit to determine whether the short SIFS duration or regular SIFS duration is defined for the communication between the access point and the station.
