Indicating persistent listen before talk failure in sidelink ungrant
By sending a bitmap in the SL-U network to indicate the continuous LBT failure of the RB set, the problem of the inability to effectively indicate the failure of each RB set in the prior art is solved, and more efficient system performance and communication efficiency are achieved.

Abstract
Various aspects of the present disclosure generally relate to wireless communications. In some aspects, a user equipment (UE) may transmit a persistent listen before talk (LBT) failure indication including a bitmap, where bits in the bitmap correspond to a set of resource blocks (RBs), and the bits indicate whether the set of RBs is associated with a persistent LBT failure. The UE may perform a sidelink communication based at least in part on a schedule, wherein the schedule is based at least in part on the persistent LBT failure indication. Numerous other aspects are described.
