Abstract:
Methods and apparatuses are described herein for determining a transmit power based on clear channel assessment (CCA) thresholds. A station (STA) associated with a first Basic Service Set (BSS) may receive, from an access point (AP) associated with the first BSS, a clear channel assessment (CCA) value for a group of STAs associated with a second BSS. The CCA value may indicate a minimum CCA threshold for a packet received from the second BSS. The STA may then determine, based on the CCA value, a STA specific CCA parameter and a target CCA parameter. The target CCA parameter may be greater than or equal to the STA specific CCA parameter. Based on the STA specific CCA parameter and the target CCA parameter, the STA may determine a target transmit power control (TPC) parameter of the STA, wherein the sum of target TPC parameter and target CCA parameter is constant.
