Abstract
A wireless device receives an uplink grant scheduling a transmission on a plurality of sub-bands of a physical uplink shared channel (PUSCH) of a cell. The plurality of sub-bands comprise a first sub-band and one or more other sub-bands. A determination is made that a first type listen-before-talk (LBT) indicates that the first sub-band of the plurality of sub-bands is clear. A determination is made that a second type LBT, performed immediately before the transmission on the first sub-band, indicates that each of the one or more other sub-bands of the plurality of sub-bands are clear. A transport block is transmitted on the plurality of sub-bands of the PUSCH, based on: the determination that the first type LBT indicates that the first sub-band is clear; and the determination that the second type LBT indicates that each of the one or more other sub-bands are clear.
