1. A method by a network node for self-deferring transmissions in a multi-carrier network, the method comprising:
determining, by a first controller seeking to initiate a carrier sensing procedure in a first cell operating on a first carrier, that a second cell associated with a second controller has initiated a first transmission opportunity after a successful carrier sensing procedure, the first transmission opportunity on a second carrier that is adjacent to the first carrier;
determining, by the first controller associated with the first cell, a first transmission opportunity duration associated with the first transmission opportunity initiated in the second cell;
deferring, by the first controller, the carrier sensing procedure to be performed in the first cell, the carrier sensing procedure deferred by the first transmission opportunity duration associated with the first transmission opportunity initiated in the second cell; and
initiating the carrier sensing procedure in the first cell after the first transmission opportunity duration unless instructed by the second controller.
