Abstract
Provided are a basic service set (BSS) load management procedure and a quiet interval setup procedure in a wireless local area network (WLAN) system. The WLAN system uses a bonding channel, and an access point (AP) of the WLAN system provides BSS load information regarding a channel having a bandwidth less than or equal to a bandwidth of the bonding channel (e.g., each of channels of 20 MHz, 40 MHz, 60 MHz, and 80 MHz) to STAs of the WLAN system. The BSS load information may be specified by an extended BSS load element. The AP transmits the extended BSS load element to the STAs by including the BSS load information to a beacon frame or a probe response frame.

A method of load management, performed by an access point (AP), in wireless local area network (WLAN) system, the method comprising:
- transmitting a frame comprising a first utilization field and a second utilization field to a station performing scanning procedure for finding a Basic Service Set (BSS),
- wherein the AP has a first subchannel and a second subchannel as operating channels on which the AP transmits frames to the station,
- wherein a bandwidth of the first subchannel and a bandwidth of the second subchannel are different,
- wherein the first utilization field is defined as a first fraction of time that the first subchannel is busy and the second utilization field is defined as a second fraction of time that the second subchannel is busy.
A wireless apparatus comprising:
- a transceiver;
- and
- a processor operatively coupled with the transceiver and configured to:
- transmit a frame comprising a first utilization field and a second utilization field to a station performing scanning procedure for finding a Basic Service Set (BSS),
- wherein the wireless apparatus has a first subchannel and a second subchannel as operating channels on which the wireless apparatus transmits frames to the station,
- wherein a bandwidth of the first subchannel and a bandwidth of the second subchannel are different,
- wherein the first utilization field is defined as a first fraction of time that the first subchannel is busy and the second utilization field is defined as a second fraction of time that the second subchannel is busy.
