  • Patent number: 11930533
    Abstract: Channel occupancy time (COT) aware sensing and resource selection for new radio-unlicensed (NR-U) sidelink operations is disclosed. A first sidelink user equipment (UE) determines a sensing window or resource selection window (RSW) based on a projected listen-before-talk (LBT) completion time. The UE may sense for a subset of sideline resources within the RSW and COT-SI from a neighboring sidelink UE including identification of a COT initiated by the neighboring UE and one or more parameters associated with the COT. The UE may identify in-COT resources of located within the COT and out-of-COT resources located outside of the COT and then randomly select a set of transmission resources from the in-COT and out-of-COT resources. The UE may then transmit to a second UE using the set of transmission resources.
