摘要:
Embodiments of an access point (AP), station (STA) and method for multi-user (MU) location measurement are generally described herein. The AP may contend for a transmission opportunity (TXOP) to obtain access to a channel. The AP may transmit a trigger frame (TF) to initiate a multi-user (MU) location measurement during the TXOP. The AP may receive service requests for the MU location measurement from a plurality of STAs. The AP may transmit an MU acknowledgement (ACK) frame that indicates reception of the service requests. The AP may receive, from the STAs, uplink sounding frames that include per-STA timing information for the service requests and the MU ACK frame. The STA may determine location measurements for the STAs based on the per-STA timing information included in the uplink sounding frames.

Embodiments of a virtual access point (VAP) and method for channel selection in a wireless network are generally described herein. The VAP may determine, from a group of channels available for VAP usage, a primary channel for the VAP based at least partly on a determination of whether the channels of the group are used as primary channels by one or more other VAPs. The VAP may transmit a downlink signal to a station (STA) in VAP channel resources that include the determined primary channel and one or more secondary channels. The VAP may use a first encryption type and a first media access control (MAC) identifier while a second VAP may use a second encryption type and a second media access control (MAC) identifier. In some embodiments, multiple VAPs may be supported by a single access point (AP).

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.
