Abstract: Methods and devices are described for providing wireless stations (STAs) with two sets of enhanced distributed channel access (EDCA) parameters. Legacy EDCA parameters that are for single user (SU) operations and may be used by both high-efficiency (HE) STAs and legacy STAs without multi-user (MU) capability. MU EDCA parameters are defined to be more restrictive than legacy EDCA parameters in favoring MU operations. Embodiments are described that define sets of rules for regulating how STAs capable of both SU and MU uplink operations can use the different sets of EDCA parameters.

Abstract: Embodiments of a station (STA), access point (AP) and method for aggregation of data packets are generally described herein. The AP may transmit a trigger frame (TF) to an STA that indicates an access class (AC) constraint parameter and a traffic identifier (TID) aggregation limit parameter. The STA may select a group of aggregate TIDs from which medium access control (MAC) protocol data units (MPDUs) may be aggregated into an aggregated MPDU (A-MPDU). The AC constraint parameter may indicate a recommended AC from which at least a portion of the aggregate TIDs are to be selected. The TID aggregation limit parameter may indicate a number of TIDs to be selected for the group of aggregate TIDs.

An apparatus of a high-efficiency wireless local-area network (HEW) master station is disclosed. The apparatus includes transceiver circuitry and processing circuitry which may be configured to generate a trigger frame for uplink random access (TF-R), and transmit the TF-R. The transceiver circuitry and processing circuitry may be further configured to receive one or more responses in accordance with orthogonal frequency division multiple-access (OFDMA) to the trigger frame from one or more pre-association stations where the responses comprise pre-association identifiers corresponding to the one or more pre-association stations. Moreover, the transceiver circuitry and processing circuitry may be further configured to generate one or more acknowledgements to the one or more pre-association stations, and transmit the acknowledgements in accordance with OFDMA to the one or more pre-association stations.

Abstract: An apparatus, computer readable medium, and method for overlapping basic service set (OBSS) indication in a high-efficiency wireless local-area network (HEW). An apparatus of a high-efficiency wireless local-area network device is disclosed. The apparatus including transceiver circuitry and processing circuitry configured to receive a frame and determine whether the frame is a frame transmitted from a basic service set (BSS) or a frame transmitted from an OBSS based on one or more media access control (MAC) addresses of the frame. The MAC address may include an indication of a BSS of the HE wireless device. If the HE wireless device is an access point, then a second part of the MAC address may be a predetermined pattern, the second part of the MAC address may be a formula applied to a first part of the MAC address, or an individual/group bit of the MAC address may be set.
