Disclosed is a polling list management method using orthogonal signaling in a wireless LAN including a plurality of terminals and a base station, the method comprising: a first step where the base station transmits a first and a second orthogonal code to the respective terminals, the orthogonal codes being unique for each terminal and "bit-wise inverse" of each other; a second step where the respective terminals having received the first and second orthogonal codes transmit one of the first and second orthogonal codes to the base station to request polling; and a third step where the base station determines whether the corresponding terminal should be polled, based on the received orthogonal code.
