Method and apparatus for transmitting management information frame in wireless local area network system

摘要

A method of transmitting management information, performed by an access point (AP), in a wireless local area network system. The method according to one embodiment includes transmitting, to a station, a frame including a basic service set (BSS) load information element, the BSS load information element including a multi user (MU) multiple input multiple output (MIMO) capable station (STA) count field and a plurality of bandwidth utilization fields. The MU-MIMO capable STA count field indicates a total number of STAB with MU reception capability currently associated with a candidate BSS managed by the AP. Each of the plurality of bandwidth utilization fields includes information about time that each corresponding channel width is busy.
