9. A wireless device (WD) comprising processing circuitry configured to:
associate each of a plurality of sets of resources with a different energy detection (ED) threshold, the resources in each set of the plurality of sets of resources being at least one of time resources and frequency resources with different energy detection thresholds, wherein each set of resources of the plurality of sets of resources associated with an ED threshold are a set of time resources assigned to a different set of WDs and each different set of WDs uses a same set of frequency resources, and wherein the ED threshold used by the WD for applying a listen-before-talk (LBT) to access a channel that is adapted based on one or more of number of carriers on which the WD is configured to transmit, position of the one or more of number of carriers in frequency and whether the transmissions of the carriers overlap or not in time.
