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.

摘要： Apparatuses, methods, and computer readable media are disclosed for fragmentation of media access control service data units (MSDU) in a high-efficiency wireless local-area network. An apparatus of a access point or station comprising memory and processing circuitry coupled to the memory is disclosed. The processing circuitry is configured to fragment a media access control (MAC) service data unit (MSDU) into two or more MSDU fragments, and encapsulate the two or more MSDU fragments into two or more aggregated MSDUs (A-MSDUs); one or more A-MSDUs and one or more MAC protocol data units (MPDUs); or, two or more MPDUs. The processing circuitry may be further configured to encode a delimiter in front of a first fragment of the two or more MSDU fragments, where the delimiter indicates a length of the two or more MSDU fragments, and to encode each MPDU to comprise a sequence number.
