RANDOM DETECTION THRESHOLD

Abstract:

This disclosure provides wireless nodes, methods, apparatus, means plus and computer-readable mediums for randomly determining detection thresholds, such as energy detection (ED) thresholds, and then using such randomly determined thresholds to determine whether a channel is busy or idle when performing clear channel access (CCA). In some implementations, a new random detection threshold may be determined at a start of each backoff or each subsequent backoff slot. In some other implementations, a range of energy from which the detection threshold is randomly determined may depend on measurements of traffic activity, the number of MAC addresses observed or the priority of the traffic.
