The circuitry may be configured to: generate a HE packet with a short preamble format or a long preamble format, wherein the HE packet comprises one or more legacy signal (L-SIG) fields followed by one or more HE signal fields (HE-SIG) and an HE long-training field (HE-LTF); and configure the HE packet to indicate whether the HE packet is configured with the short preamble format or the long preamble format. The HE packet may be configured with the short preamble format or the long preamble format based on one from the following group: a symbol after the L-SIG fields, a L-SIG polarity of a repeated L-SIG, a number of times the L-SIG fields is repeated, or a length field of one of the one or more L-SIG fields.

    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.
