Abstract
Systems, methods, and devices for addressing wideband unlicensed channel access are disclosed herein. A device may be configured for different types of listen-before-talk (LBT) procedures, where the LBT type may refer to the frequency granularity of the LBT. There may be a hierarchical LBT procedure, where the LBT granularity changes at each point in the LBT procedure. There may be a selection of parameters for each LBT type. Some of the parameters may be shared over different points of the LBT procedure. There may be LBT subband sets for a subband set LBT type. There may be one or more indications of acquired LBT subbands on a condition of shared channel occupancy time. At one point in the LBT procedure, there may be a selection of a LBT subband or one or more subbands sets for transmission based on one or more criteria.
