Abstract:
Systems and methods for Carrier Sense Adaptive Transmission (CSAT) communication scheme identification and mitigation in unlicensed spectrum are disclosed. The identification may comprise, for example, identifying CSAT communication based on a presence of a first signal and an absence of a second signal of a Radio Access Technology (RAT) during a period of time. The mitigation may comprise, for example, limiting transmission of at least a first signal by the RAT on a resource for a period of time associated with an adaptable duty cycle used for the CSAT communication, and transmitting a second signal by the RAT on the resource during the period of time.
