Abstract: An apparatus of a first high-efficiency (HE) access point (AP) or station for spatial reuse is the disclosed. The apparatus includes processing circuitry configured to: decode a first portion of a first packet; and if the first portion indicates the first packet was transmitted by a second HE AP or station and that the first packet is an overlapping basic service set (OBSS) packet, then if a preamble detect energy is below a threshold, cause to be transmitted a second packet simultaneously with a portion of the first packet after the first portion. The processing circuitry may be configured to determine the first portion was transmitted by the second HE AP or station if a field in a physical (PHY) header or a second field in a media access control (MAC) header indicate the first packet was transmitted by the second HE AP or station.

Abstract: Embodiments of a station (STA), access point (AP) and method for rate adaption are generally described herein. The STA may receive a medium access control protocol data unit (MPDU) encoded in accordance with a first modulation and coding scheme (MCS). The STA may detect bit errors of the MPDU based on a comparison between the received MPDU and the decoded MPDU. The STA may determine an MCS reception margin parameter based at least partly on a comparison between a number of detected bit errors and a predetermined threshold of bit errors. The STA may transmit a block acknowledgement (BA) frame that includes the MCS reception margin parameter. The MCS reception margin parameter may enable a rate adaptation, from the first MCS to a second MCS for a subsequent MPDU for the STA.
