Clear channel assessment (CCA) threshold adaptation method

A station (STA) comprising:

• a processor;
• and
• a transceiver,
• the processor and the transceiver configured to:
• receive, from an access point (AP) associated with a Basic Service Set (BSS), a transmit power control (TPC) clear channel assessment (CCA) constant for a wireless network comprising the BSS and a neighboring BSS, wherein the TPC CCA constant indicates a CCA threshold for a group of STAs associated with the neighboring BSS;
• determine, based on the TPC CCA constant and a transmit power selected by the STA, a STA specific CCA threshold to be used by the STA;
• and
• transmit, based on the determined STA specific CCA threshold, to the AP, one or more frames.
