1. A method of Carrier Sense Adaptive Transmission (CSAT) for reducing interference between Radio Access Technologies (RATs), comprising:

  • receiving signals via a resource, wherein a first RAT is used to receive the signals;

    identifying utilization of the resource associated with the first RAT, wherein the identification is based on the received signals;

    cycling operation of a second RAT between activated and deactivated periods of transmission over the resource in accordance with a Time Division Multiplexing (TDM) communication pattern, wherein the cycling is based on the identified utilization of the resource; and

    transmitting an Activation/Deactivation Medium Access Control (MAC) Control Element (CE) to a user device associated with the second RAT to activate or deactivate the user device in accordance with the TDM communication pattern.
