Abstract: Disclosed is a method for transmitting data in a wireless network employing an access point. Each transmission opportunity for transmitting data between the access point and each station is set by using channel state information and traffic state information in relation to stations existing in the same communication area with the access point in a wireless network employing the access point, so that overheads can be reduced and a data processing amount can be improved.

Abstract: A method for increasing transmission efficiency between stations by representing and using a new media access control (MAC) frame format for a management frame of the 802.11a standard in wireless network communication. The method including securing transmission media through a predetermined channel securing procedure at one or more Multiple Input/Multiple Output (MIMO) transmission stations, and constructing information associated with a basic service set (BSS) and a MIMO Supported Rate and carrying the information associated with the BSS and MIMO Supported Rate on the management frame at the MIMO transmission station and transmitting the carried information to at least one reception-sided station by means of the transmission media.
