METHOD AND DEVICE FOR TRANSMITTING AND RECEIVING FRAME USING SHORT GUARD INTERVAL

摘要

Disclosed are a method and a device for transmitting and receiving a frame using a short guard interval. A method for receiving a beacon frame comprises the steps of: receiving a first beacon frame which contains guard interval type information; determining a second beacon frame which is to be received after the first beacon frame on the basis of the guard interval type information; and receiving the second beacon frame, wherein the guard interval type information may be information which is related to a guard interval used when said second beacon frame is transmitted. Thus, since a station can determine whether to receive a frame using a certain guard interval, the station can receive a power-saving effect.
