1. A method for use in a station (STA) associated with a Basic Service Set (BSS), the method comprising:
receiving, from an access point (AP) associated with the BSS, a first Clear Channel Assessment (CCA) value and a second CCA value, wherein both the first CCA value and the second CCA value are used to determine a first STA specific CCA parameter and a second STA specific CCA parameter for a group of STAs associated with an overlapping Basic Service Set (OBSS), the first CCA value indicating a minimum CCA threshold for one or more packets received from the OBSS and the second CCA value indicating a maximum CCA threshold for one or more packets received from the OBSS;
determining, based on the first STA specific CCA parameter and the second STA specific CCA parameter, a target CCA parameter, wherein the target CCA parameter is greater than the first STA specific CCA parameter and less than or equal to the second STA specific CCA parameter; and
transmitting, using a transmission power determined based on the target CCA parameter, a frame, wherein a sum of the transmission power and the target CCA parameter is constant.
