    摘要： In a network that contains both new devices capable of using wide channels and legacy devices that can only use narrow channels, the network controller may define which devices are to use which narrow channels for concurrently transmitting uplink acknowledgements. Further, the network controller may schedule the devices to respond in groups based on the received signal strength of their transmissions at the network controller.

    摘要： Systems and techniques for random access to a wireless network are described herein. Components of a wireless station may obtain a back-off value. The components may also decode random access resource units from a frame transmitted to the wireless station from an access point of the wireless network. The components may decrement the back-off for each decoded random access frame. The wireless station may select this frame from a sequence of frames when the back-off reaches zero while decoding the random access resource units of this frame. The wireless station then selects the random access resource unit with a more favorable transmission metric than another random access resource unit of the frame and uses the selected random access resource unit to communicate with the access point.

    摘要： Wireless devices, methods, and computer-readable media for transmitting and receiving beacon frames are disclosed. A master station is disclosed. The master station may include circuitry configured to operate in accordance with orthogonal frequency division multiple access (OFDMA) on a plurality of sub-channels and a primary channel. The circuitry may be further configured to assign a high-efficiency wireless local-area network (HEW) station to a sub-channel and transmit a legacy beacon on the primary channel with a first period. The circuitry may be further configured to transmit a HEW beacon on the sub-channel with a second period, wherein the second period is greater than the first period. The circuitry may be further configured to determine that the HEW station has data at the master station, and to transmit the HEW beacon on the sub-channel with an indication that the HEW station has the data. A HEW station is disclosed for receiving HEW beacons.

    摘要： Apparatuses, methods, and computer readable media are disclosed. A HE station may include circuity. 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.
