Certain aspects of the present disclosure provide techniques for reuse one channel access for new radio communications in unlicensed spectrum. A method that may be performed by a first base station (BS) includes occupying a bandwidth, based on a category 4 (CAT4) listen before talk (LBT) procedure on the bandwidth, wherein the CAT4 LBT procedure is based on a first contention window (CW); arranging a category 2 (CAT2) LBT occasion for the bandwidth during a channel occupancy time (COT) for the bandwidth; and receiving an indication that at least a second BS has occupied the bandwidth during the CAT2 LBT occasion.
