摘要： The present invention relates to a technique relating to a method and apparatus for generating, transmitting, and receiving a data frame having a newly proposed format in a wireless communication system. According to the technique, the method for generating a data frame in a wireless communication system comprises the following steps: generating at least one first subframe; generating at least one second sub frame; and generating a data frame including the first and second subframes, wherein the first and second subframes include length information of a MAC protocol data unit (MPDU) contained in the and second subrames, and the length information of the MPDU contained in the second subframe is zero.

摘要： 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.
