A system and method of terminating any pending listen-before-talk (LBT) attempts after they have been submitted to the physical layer of a system interconnection model if one or more of the LBT attempts succeed. The system and method include receiving a plurality of frequency resources, each of the plurality of frequency resources corresponding to a respective resource occasion. The system and method include performing, for each of the frequency resources, a listen-before-talk procedure in a first layer of an open system interconnection model. The system and method include indicating, to a second layer of the open system interconnection model, a first one of the plurality of frequency resources that succeeded in the respective listen-before-talk procedure.
