Method for providing information of access point selection

A device configured to transmit basic service set (BSS) load information in a wireless local area network, the device comprising:

• a communication device;
• and
• a processor operatively connected to the communication device and configured to:
• establish an association with at least one very high throughput (VHT) station that has successfully synchronized with the device that has a capability of receiving at least one spatial stream of a plurality of spatial streams transmitted via a multi user-multiple input multiple output (MU-MIMO) transmission, and
• instruct the communication device to broadcast a beacon frame that includes load information including a station count field and an antenna utilization field,
• wherein the station count field indicates a number of the at least one VHT station that has successfully synchronized with the device and that has the capability of receiving the at least one spatial stream of the plurality of spatial streams transmitted via the MU-MIMO transmission, and
• wherein the antenna utilization field indicates information about an under-utilization of spatial streams in the MU-MIMO transmission.

A method of selecting an access point (AP) in a wireless local area network system, the method comprising:

• receiving, by a scanning station from the AP a beacon frame including load information including a station count field and an antenna utilization field;
• and
• determining, by the scanning station based on the load information, whether a station requests association with the AP or not,
• wherein the station count field indicates a number of at least one very high throughput (VHT) station that has successfully synchronized with the AP and that has a capability of receiving at least one spatial stream of a plurality of spatial streams transmitted via a multi user-multiple input multiple output (MU-MIMO) transmission, and
• wherein the antenna utilization field indicates information about an under-utilization of spatial streams in the MU-MIMO transmission.
