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

A device for a wireless local area network, the device comprising:

• a transceiver configured to transmit radio signals;
• and
• a processor operatively coupled with the transceiver and configured to:
• determine first utilization information for a first channel having a bandwidth of 40 MHz;
• and
• instruct the transceiver to transmit basic service set (BSS) load information, the BSS load information including a multi user (MU) multiple input multiple output (MIMO) capable station count field and the first utilization information,
• wherein the MU-MIMO capable station count field indicates a total number of stations with MU reception capability currently associated with a BSS managed by the device, and
• wherein the first utilization information includes information about a time during which the first channel is busy.

A method for a wireless local area network system, the method comprising:

• receiving, by a station, basic service set (BSS) load information from an access point (AP);
• and
• establishing, by the station, a connection with the AP based on the BSS load information,
• wherein the BSS load information including a multi user (MU) multiple input multiple output (MIMO) capable station count field and a first utilization field,
• the MU-MIMO capable station count field indicating a total number of stations with MU reception capability currently associated with a BSS managed by the AP,
• the first utilization information including information about a time during which a first channel having a bandwidth of 40 MHz is busy.
