Techniques for communication management between Radio Access Technologies (RATs) sharing operating spectrum in an unlicensed band of radio frequencies are disclosed. Interference may be mitigated by, for example, receiving signaling via a resource. A first RAT may be used to receive the signaling. Based on the received signaling, utilization of the resource associated with the first RAT may be identified. The identified utilization of the resource may be classified based on an attribute associated with the received signaling and a plurality of thresholds associated with the attribute. The plurality of thresholds may define different classes of utilization. Communication by a second RAT over the resource may be adapted based on the classified utilization of the resource.
