A first base station central unit (BS-CU) communicates, with one or more wireless devices, packets via a first cell operating in an unlicensed spectrum. The BS-CU receives, from a first base station distributed unit (BS-DU), a channel occupancy ratio (CR) of the first cell, wherein the CR is for a plurality of time intervals and indicates utilization of unlicensed channel resources that have been utilized for transmissions by the first cell. The BS-CU transmits, to a second base station, the CR.
