Device and method of setting clear channel assessment threshold
Abstract:
Aspects of the disclosure include a device that operates within a network service set. The device includes a transceiver configured to receive signals in a primary channel and in a secondary channel and a processing circuit. The processing circuit is configured to store a first clear channel assessment (CCA) threshold associated with signals from outside the network service set that are decodable by the device (OBSS_PD level), set a secondary channel CCA threshold to be equal to a level based on the OBSS_PD level, the secondary channel CCA threshold being associated with signals in a secondary channel, and determine whether a reception power level of a received secondary channel signal exceeds the secondary channel CCA threshold.
