Power control methods and procedures for wireless local area networks

An access point (AP) configured for interference coordination in a wireless local area network (WLAN), the AP comprising:

• a transmitter configured to transmit a measurement request to a plurality of mobile stations (STAs) in the WLAN;
• a receiver configured to receive a measurement report from each of the plurality of mobile STAs, wherein each measurement report includes a clear channel assessment (CCA) threshold margin value and a CCA busy fraction measurement value;
• a processor configured to determine whether to modify transmission power in the WLAN and a CCA threshold for the WLAN based on each received measurement report;
• and
• the transmitter further configured to transmit a CCA modification element to the plurality of STAs on a condition that the CCA threshold for the WLAN is modified, wherein the CCA modification element includes a modified CCA threshold value.

A mobile station (STA) configured for interference coordination in a wireless local area network (WLAN), the STA comprising:

• a receiver configured to receive a measurement request from an access point (AP);
• a transmitter configured to transmit a measurement report measurement to the AP, wherein the measurement report includes a clear channel assessment (CCA) threshold margin value and a CCA busy fraction measurement value;
• the receiver further configured to receive from the AP a CCA modification element, wherein the CCA modification element includes a modified CCA threshold value;
• and
• the receiver further configured to receive a modified transmission power from the AP.
