    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.

    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： An apparatus, a method and a machine-readable storage medium to accommodate both high function and low cost wireless devices in a wireless network. 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： Systems, devices, and methods for mitigating collisions between wireless transmissions operating at different bandwidths are disclosed. As such, a wireless device operating at a predefined bandwidth includes a transceiver that receives a signal across a wireless channel, a filter that generates a band-limited filtered signal at the predefined bandwidth of the wireless device, a correlating mechanism that correlates the band-limited filtered signal with a delayed, conjugated version of the band-limited filtered signal, logic that performs a moving average of the correlated filtered signals to determine correlation peaks, and logic configured to compare the correlation peaks with a predetermined threshold. With this configuration, if the correlation peaks are greater than the predetermined threshold, the received signal is determined to operate at a wider bandwidth than the predefined bandwidth of the wireless device, and the wireless device defers accessing the wireless channel to transmit until a predetermined time interval.
