Abstract: The present invention relates to a method and apparatus for transceiving data. A method in which a transmitting terminal transmits data to a receiving terminal in a MIMO system according to one embodiment of the present invention comprises the following steps: generating a data field containing the data; generating a signal field containing information on the data field; generating a data frame containing the data field and the signal field; and transmitting the data frame to the receiving terminal. According to the present invention, an end of the frame being transmitted is accurately notified to the receiving terminal in a communication system in which the frame is transmitted using MIMO, thereby decoding the frame in a more efficient manner at the receiving terminal.

Abstract: A method for guaranteeing a data frame transmit opportunity in a wireless LAN system having three different transmission modes includes: setting a first transmission protection interval based on a lowest transmission mode, when a node of a mode having a lowest transmission rate among the three transmission modes exists in the wireless LAN system, aggregating a data frame to be transmitted within time of the set transmission protection interval, and transmitting the data frame; and setting a second transmission protection interval based on a mode having a highest transmission rate, when only nodes of a mode having a highest transmission rate among the three transmission modes exist, aggregating a data frame to be transmitted within time of the set transmission protection interval, and transmitting the data frame.
