An IEEE 802.11 station (STA) may dynamically calculate a STA specific transmit power control (TPC) value and a STA specific clear channel assessment (CCA) value based on a target TPC parameter and a target CCA parameter. The target TPC parameter and the target CCA parameter may be received from an IEEE 802.11 cluster head configured to control TPC and CCA for a plurality of STAs associated with the BSS. The target TPC parameter and the target CCA parameter also may be related. The STA may then determine 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 STA specific CCA value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Clear channel assessment (CCA) threshold adaptation method","description":"Methods and apparatuses are described herein for adapting clear channel assessment (CCA) thresholds with or without Transmit Power Control (TPC) are disclosed.
