A method of wireless communication, comprising: selecting, at an access point (602; 710), a value for a medium access parameter for each individual communication session between the access point (602; 710) and each of a plurality of wireless stations (720; 730; 770), the medium access parameter comprising at least a clear channel assessment threshold, wherein the value for the clear channel assessment threshold is selected based on a path loss between the access point and the wireless station, and wherein selecting the value comprises: selecting, at the access point (602; 710), a first value for the medium access parameter for a first communication session between the access point (602; 710) and a first wireless station within the plurality of wireless stations (720; 730; 770), and selecting, at the access point (602; 710), a second value for the medium access parameter for a second communication session between the access point (602; 710) and a second wireless station within the plurality of wireless stations (720; 730; 770), the first value being different from the second value, wherein the access point is configured to have a lower value for the threshold when the access point is transmitting at a higher power level; and communicating, at the access point, with each of the wireless stations using the selected value for the medium access parameter for each individual communication session. selecting, at an access point (602; 710), a value for a medium access parameter for each individual communication session between the access point (602; 710) and each of a plurality of wireless stations (720; 730; 770), the medium access parameter comprising at least a clear channel assessment threshold, wherein the value for the clear channel assessment threshold is selected based on a path loss between the access point and the wireless station, and wherein selecting the value comprises: selecting, at the access point (602; 710), a first value for the medium access parameter for a first communication session between the access point (602; 710) and a first wireless station within the plurality of wireless stations (720; 730; 770), and selecting, at the access point (602; 710), a second value for the medium access parameter for a second communication session between the access point (602; 710) and a second wireless station within the plurality of wireless stations (720; 730; 770), the first value being different from the second value, wherein the access point is configured to have a lower value for the threshold when the access point is transmitting at a higher power level; and communicating, at the access point, with each of the wireless stations using the selected value for the medium access parameter for each individual communication session. selecting, at the access point (602; 710), a first value for the medium access parameter for a first communication session between the access point (602; 710) and a first wireless station within the plurality of wireless stations (720; 730; 770), and selecting, at the access point (602; 710), a second value for the medium access parameter for a second communication session between the access point (602; 710) and a second wireless station within the plurality of wireless stations (720; 730; 770), the first value being different from the second value, wherein the access point is configured to have a lower value for the threshold when the access point is transmitting at a higher power level; and communicating, at the access point, with each of the wireless stations using the selected value for the medium access parameter for each individual communication session.
