US 2009/0154405 A1 · MEDIUM ACCESS CONTROL METHOD AND DATA TRANSMISSION METHOD USING THE SAME IN WIRELESS LOCAL AREA NETWORK

Abstract

Provided are a MAC method and a method for transmitting data using the same in a WLAN. The MAC method includes: transmitting a bandwidth scheduling report frame for informing information on downlinks and uplinks allocated to a terminal by including the bandwidth scheduling report frame in one of the downlinks where the bandwidth scheduling report frame includes a plurality of downlinks, a plurality of uplinks, and a plurality of short uplinks and the number of the plurality of downlinks is equal to the number of the plurality of uplinks; receiving a bandwidth request frame for requesting bandwidth allocation through one of the uplinks; and allocating a bandwidth to each of the terminals by an unit of the downlink and the uplink.
