Abstract
In one embodiment, a method for setting a clear channel assessment (CCA) threshold includes receiving, by a station from a first access point, a first message including an information element and determining a CCA threshold in accordance with the information element. The method also includes detecting a power level of a channel between the station and the access point to produce a first detected power level and comparing the first detected power level and the CCA threshold. Additionally, the method includes 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.
