Abstract: Embodiments of an access point (AP), station (STA) and method of communication are generally described herein. The AP may include a used basic service set (BSS) color in a downlink physical layer convergence procedure protocol, data unit (PPDU). The used BSS color may indicate communication between the AP and associated STAs. The AP may detect another PPDU from an STA that is un associated with the AP. If a header portion of the detected PPDU includes the used BSS color, the AP may: determine an alternate BSS color, and transmit a color switch announcement (CSA) element that indicates the alternate BSS color. The CSA element may be configurable to further indicate whether the AP and the associated STAs are to switch, from the operating channel to an alternate channel for the communication.

Abstract: Embodiments of a user station (STA), access point (AP), and method for random access contention in a wireless network are generally described herein. The STA may receive, from the AP, a beacon frame for a beacon interval. The STA may further receive a first random access Trigger Frame (TF) that indicates a first allocation of channel resources for random access contention by STAs during a first uplink transmission period of the beacon interval. The beacon frame may include a transmission timing for the first random access TF and a first TF cascade type for the first random access TF. The first TF cascade type may indicate whether a next TF is a random access TF or a scheduled access TF.

Abstract: An exemplary aspect is directed toward methods, apparatus, and systems related to spatial reuse with overlapping basic service set. A device may determine an overlapping basic service set (OBSS) associated with one or more access points. The device may then reduce a transmit power by a first margin. The device may then increase a packet detection threshold associated with the OBSS by a second margin. The device then sends an uplink data frame to at least one of the one or more access points.

Abstract: Embodiments of an access point (AP), station (STA) and methods of communication are generally described herein. The AP may transmit a trigger frame (TF) that indicates resource units (RUs) that are available for contention based access by STAs for a fine timing measurement (FTM) protocol. The AP may attempt to decode one or more initial fine timing measurement request (iFTMR) frames received in the indicated RUs. The AP may transmit a broadcast acknowledgement (ACK) frame that indicates whether at least one iFTMR frame was decoded. The AP may, for a decoded iFTMR frame: allocate the RU corresponding to the decoded iFTMR frame to a corresponding STA for the FTM protocol; and transmit, in the corresponding RU, an initial fine timing measurement (iFTM) frame that includes an identifier of the corresponding STA.

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.

Abstract: Methods, apparatuses, and computer readable media for pre-association frame exchange using random access are disclosed. 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.
