Abstract:
This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for UL LBT status reporting. A scheduled node (e.g., a UE) may sense a status of each LBT channel in a set of one or more LBT channels. The set of one or more LBT channels may include at least one of one or more first LBT channels associated with a scheduling grant or one or more second LBT channels unassociated with the scheduling grant. The scheduled node may transmit, to a scheduling node (e.g., a base station), a LBT status report indicative of the status of each LBT channel in the set of one or more LBT channels. The scheduling node may schedule, via a second scheduling grant, a second set of one or more LBT channels based on the status of each LBT channel indicated in the LBT status report.
