Abstract: The present invention relates to a technique of transferring a frame, which is transferred to each user, by binding the frame in one aggregated frame in a physical layer level, when an access point (AP) transfers the frame to multiple users existing in one group in a wireless communication system using a wireless LAN standard which supports the users. An objective of the present invention is to increase a data throughput of entire network by reducing a signal transferred commonly upon transferring the frame separately to each user, by binding the frame, which is transferred to the users existing in one same group, in the aggregated frame.
