Sidelink LBT type indication for UE to UE COT sharing

A communication device is configured to share sub-channel resources from among available sidelink channel resources with second devices. The device transmits a sidelink channel occupancy sharing indicator that enables at least two devices to transmit data utilizing available sidelink channel resources within a channel occupancy duration. The sidelink channel occupancy sharing indicator includes a value for a selected listen before talk (LBT) type from among multiple LBT types for channel sensing. The LBT type signals to a second device receiving the sidelink channel occupancy sharing indicator which LBT procedure to utilize before accessing resources identified by the sidelink channel occupancy sharing indicator. The device allocates the available sidelink channel resources to the at least two devices to enable multiple devices to cooperatively share available sidelink channel resources via non-overlapping time or frequency domain usage in order to achieve a channel occupancy threshold level of resource utilization in an unlicensed spectrum.
