Abstract
An access point including a receiving module to receive first information indicating whether a first device supports a dynamic clear channel assessment (CCA) capability, which includes an ability to dynamically change a CCA threshold in a frequency channel to detect whether a medium is idle or busy. A CCA module generates second information in response to receiving the first information about the first device. The second information is based on the first information and indicates a CCA method used by the access point in response to receiving the first information. A transmitting module transmits the second information in response to receiving the first information about the first device. The second information is usable by one or more devices associated with the access point in a basic service set of the access point to select respective CCA procedures to detect whether the medium is idle or busy.
