Abstract

A method of data transmission employing frame bursting to improve traffic in a WLAN system. According to a representative embodiment of the invention, a variable parameter set, VPS[n], is provided to a channel access function in the process of obtaining a transmission opportunity (TXOP) for a corresponding access category, AC-n, at a wireless station of the WLAN system. The variation of one or more values in VPS[n] is based on the amount of buffered traffic and is preferably performed such that, when a TXOP is granted, AC-n has buffered an amount of traffic suitable for transmission using frame bursting in such a manner that the service and back-off overheads for AC-n are substantially reduced. Due to the overhead reduction, more channel time becomes available to traffic from other access categories and/or wireless stations. For example, bursting video traffic in accordance with the invention may significantly improve best-effort traffic. In addition, less channel time may be lost to collisions.
