Abstract: 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.

Abstract: Embodiments of a high-efficiency Wi-Fi (HEW) station, access point (AP), and method for random access contention in a wireless network are generally described herein. In some embodiments, the HEW station may receive a beacon frame that indicates a number of trigger frames (TFs) included in a beacon interval. The beacon frame may be received from an HEW access point (AP) in channel resources that include multiple sub-channels. The HEW station may receive a random access TF that indicates a random access portion of the sub-channels that are allocated for random access contention during an uplink transmission period. The HEW station may select a candidate sub-channel from the channel resources. When the candidate sub-channel is included in the random access portion, the HEW station may transmit an association request (AR) frame on the candidate sub-channel during the uplink transmission period.

Abstract: Logic may transmit or receive communications that hop frequencies in response to trigger events across a large bandwidth. Logic may generate a communication with a contiguous or non-contiguous bandwidth based upon frequency segments of 80 and/or 160 MHz. Logic may generate a communication with a contiguous bandwidth of 480 MHz. Logic may generate a communication with a non-contiguous bandwidth of 480 MHz. Logic may transmit or receive communications with a 480 MHz bandwidth that hop across a 3 GigaHertz (GHz) bandwidth of frequency channels. Logic may determine a channel-hopping pattern. Logic may hop frequency channels after each link transmission. Logic may hop channels after a fixed time interval. And logic may hop frequency channels in response to another triggering event.
