Method and apparatus for managing quantity of data to be transmitted in a wireless network

A method of communication in a wireless network comprising a plurality of wirelessly communicating stations, one station playing the role of access point, the other stations being connected to the access point station, the method comprising by the access point station:

• receiving at least one buffer status report from a station indicating an amount of data the station has to transmit to the access point station;
• storing received buffer status reports;
• generating a channel resource allocation for a multi-user transmission from the stations to the access point station based on stored buffer status reports;
• wherein the generation of a channel resource allocation further takes into account any amount of data received from the stations after the buffer status reports;
• and
• upon reception of a data frame from one station, and if a buffer status report is comprised within the received data frame, storing the received buffer status report.
