Clear channel assessment (CCA) threshold adaptation method

An Institute of Electrical and Electronics Engineers (IEEE) 802.11 station (STA), the STA comprising:

• a receiver configured to receive a target transmit power control (TPC) parameter and a target clear channel assessment (CCA) parameter from an IEEE 802.11 cluster head configured to control TPC and CCA for a plurality of STAs associated with a basic service set (BSS);
• a processor configured to dynamically calculate, at the STA, a STA specific TPC value and a STA specific CCA value based on the target TPC parameter and the target CCA parameter, wherein a product of the target TPC parameter and the target CCA parameter is a constant;
• and
• the STA configured to determine whether a carrier sense multiple access (CSMA) wireless medium of a wireless local area network (WLAN) BSS is occupied or idle based on the STA specific CCA value.

A method for use in a network node, the method comprising:

• receiving a target clear channel assessment (CCA) parameter from an IEEE 802.11 cluster head configured to control transmit power control (TPC) and CCA for a plurality of network nodes, wherein a product of the target CCA parameter and a TPC parameter is a constant;
• dynamically calculating, at the network node, a network node specific CCA value based on the target CCA parameter and based on a frame type, wherein the frame type is a data frame with one destination or a control frame with a plurality of destinations;
• and
• determining whether a carrier sense multiple access (CSMA) wireless medium of a wireless local area network (WLAN) basic service set (BSS) is occupied or idle based on the network node specific CCA value.
