Abstract: A MAC(Media Access Control) protocol in a wireless local area network and a data transmission method using the same are provided to make a wireless LAN terminal device request allocation of necessary bandwidth by a super frame unit to allocate the bandwidth by a wireless LAN base station in order to release allocation of unnecessary bandwidth, thereby efficiently using a limited bandwidth. If there is an uplink which is not allocated to any terminal device, a wireless LAN terminal device transmits a BR(Bandwidth Request) frame to a wireless LAN base station requesting necessary bandwidth through a short uplink or the uplink(302,303). The wireless LAN base station allocates downlinks and uplinks of a new super frame properly for a bandwidth that each terminal device needs(304). The allocated information is reported to all terminal devices through a BSR frame(305).
