Multi-user communication in wireless networks

Abstract

A first wireless device operating in a wireless network generates a frame and transmits the frame to a second wireless device operating in the wireless network. Generating the frame includes inserting, into a Quality of Service (QoS) field of the frame or into a High Throughput (HT) Control field of the frame, buffer status information for one or more traffic identifiers (TIDs). Generating the frame may also include inserting, into the QoS or HT Control field, an indication whether the buffer status information represents all TIDs active between the first and second wireless device. A first wireless device operating in a wireless network receives a frame from a second wireless device operating in the wireless network, and decodes the frame. Decoding the frame includes determining, using a QoS field of the frame or using a HT Control field of the frame, buffer status information for multiple TIDs.
