transmitting, to a wireless node, a request for a status report of an unlicensed band associated with an unlicensed channel access of the wireless node;
receiving, from the wireless node and based at least in part on transmitting the request, the status report, wherein the status report indicates:
a quantity of listen-before-talk (LBT) failures during the unlicensed channel access of the wireless node, and
communication failures during a channel occupancy after an LBT; and
transmitting, to the wireless node, an updated configuration for unlicensed channel access for the wireless node based at least in part on the status report of the unlicensed band, wherein the control node is a base station control unit (gNB-CU) and the wireless node is a base station distributed unit (gNB-DU).
