In 802.11ac and earlier standards, the mechanism of dynamically adjusting the clear channel assessment (CCA) threshold is used to reduce co-channel interference. The system identifies the co-channel interference strength, dynamicaly adjusts the CCA threshold, ignores co-channel weak interference signals...
