Abstract
Systems, devices, and techniques for wideband operations in unlicensed spectrum are described. A described technique receiving, by a user equipment (UE), a schedule for transmitting on a Physical uplink shared channel (PUSCH) over at least a portion of a plurality of listen-before-talk (LBT) subbands of a bandwidth part (BWP) in an unlicensed spectrum. The scheduled PUSCH bandwidth indicated by the schedule can be greater than a unit bandwidth of a LBT subband. The technique includes performing, by the UE, a LBT procedure on each scheduled LBT subband of the plurality of LBT subbands, each of the scheduled LBT subbands being associated with the scheduled PUSCH bandwidth. The technique includes performing, by the UE, a PUSCH transmission in accordance with the schedule that uses one or more of the scheduled LBT subbands that have passed the LBT procedure.
