Abstract: Some embodiments relate to methods, computer readable media, and apparatus for resolving acknowledgements between associated and unassociated stations. An apparatus is disclosed including processing circuitry configured to decode responses to a random-access trigger frame, wherein one of the responses is a response from an unassociated station. The processing circuitry may be further configured to: encode an acknowledgement to acknowledge receipt of the response from the unassociated station, where the acknowledgement comprises an indication that the acknowledgement is for the unassociated station, and where the acknowledgement further comprises a media access control (MAC) address of the unassociated station in a field of the acknowledgement other than a field in a MAC header portion of the acknowledgement. The processing circuitry may configure the HE access point to transmit the acknowledgement.

Abstract: New wireless networks can perform enhanced beamforming training for a multiple access technique, such as orthogonal frequency division multiple-access (OFDMA). The configurations of the stations and the networks presented herein provide a multiple-station beam refinement protocol (MSBRP) that may be used to train the transmit end and/or the receive end for the stations in a dense wireless local area network (WLAN). The MSBRP can have at least two phases. The first phase concurrently trains the receive side of multiple responder stations from one set of training signals sent from an initiator station. Then, each responder station can send training signals to the initiator station in a set of ordered phases associated with each responder station. The MSBRP eliminates inefficiencies associated with conducting multiple BRPs that include only pairs of stations.

Abstract: Techniques for implicit indication of trigger frame start times are described. In various embodiments, an AP may be configured to transmit a trigger frame at the beginning of each target wake time (TWT) interval. In some embodiments, each STA that uses a given TWT interval may be configured to treat a TWT Start Time received from the AP not only as a start time for that TWT interval but also as a start time for the trigger frame to be received from the AP. In various embodiments, each STA in a TWT Group may wait to receive the trigger frame from the AP upon awakening during its TWT interval. The embodiments are not limited in this context.

Abstract: Embodiments of a station (STA) and method for communication on primary and secondary channel resources are generally described herein. The STA may transmit a grant frame to indicate a transmission of a data payload by the STA during a grant period. The grant frame may indicate whether the data payload is to be transmitted on primary channel resources or on secondary channel resources. The STA may transmit the data payload to a destination STA on the secondary channel resources when the grant frame indicates that the data payload is to be transmitted on the secondary channel resources. The grant frame may be transmitted on the primary channel resources and on the secondary channel resources when the grant frame indicates that the data payload is to be transmitted on the secondary channel resources.

Abstract: Apparatuses, methods, and computer readable medium for access categories (ACs) and enhanced distributed channel access functions for trigger frames are disclosed. An apparatus of a wireless device is disclosed. The apparatus comprises processing circuitry configured to contend for access to a wireless medium of a channel with a first access category (AC), where the first AC comprises a first transmission opportunity (TXOP) limit, a first contention window minimum (CWmin), a first contention window maximum (CWmax), and a first arbitration inter-frame space (AIFS) number (AIFSN), and where the wireless device is to contend for the wireless medium in accordance with the first CWmin, the first CWmax, and the first AIFSN. The processing circuitry configured to transmit a trigger frame with a second AC to the stations, where the trigger frame is to start a TXOP with the first TXOP limit, when access to the channel is gained with the first AC.

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.
