Abstract
Methods and devices are described that facilitate uplink multi-user acknowledgment transmissions. In particular, acknowledgment information may be located in a media access control (MAC) header of a payload section of a MAC Protocol Data Unit within a downlink multi-user frame. The acknowledgment information may be present in each resource unit of the downlink multi-user frame to indicate to each corresponding station properties/characteristics of a subsequent acknowledgment transmission. The properties may include one or more of (1) whether the acknowledgement transmission is multi-user or single user, (2) whether the acknowledgement transmission is transmitted immediately following receipt of the downlink multi-user frame or upon receipt of a multi-user block acknowledgement request frame, and (3) resource scheduling information for an uplink multi-user acknowledgement transmission.
