Abstract
Disclosed is a method for alleviating a hidden node problem in a wireless local area network (WLAN) system. A method for detecting a hidden node comprises the steps of: configuring a first restricted access interval used for a plurality of terminals transmitting a hidden node detection frame; configuring a second restricted access interval used for a plurality of terminals transmitting a hidden node report frame generated on the basis of an HND frame; generating a beacon including configuration information of the first restricted access interval and configuration information of the second restricted access interval; and transmitting the generated beacon. Accordingly, a terminal in a hidden node relation can be detected.
