Claim:
1. A method for detecting a hidden node by an access point, the method comprising: setting at least one first time slot of a first restricted access window for allowing at least one of multiple terminals to transmit a hidden node detecting (HND) frame within the first restricted access window, and for allowing another terminal to transmit an HND frame in a second time slot that is not allocated to the at least one terminal; setting at least one second time slot of a second restricted access window for allowing the multiple terminals to transmit hidden node reporting (HNR) frames generated based on the HND frame within the second restricted access window; generating a beacon including setting information of the at least one first time slot of the first restricted access window and setting information of the at least one second time slot of the second restricted access window; and transmitting the generated beacon.
