Claim Text:
1. A method for setting a clear channel assessment (CCA) threshold, the method comprising: receiving, by a station from a first access point, a first message comprising an information element; determining a CCA threshold in accordance with the information element; detecting a power level of a channel between the station and the access point to produce a first detected power level; comparing the first detected power level and the CCA threshold; when the first detected power level is less than the first CCA threshold, detecting a path loss between the station and the access point and generating a second CCA threshold based on the first CCA threshold and the path loss; and transmitting, by the station to the first access point on the channel, a second message when the detected power level is less than the CCA threshold, with the second message including the second CCA threshold.
