1. A method comprising:

receiving, by a wireless device, a grant scheduling a transmission on sub-bands of a physical uplink shared channel of a cell, wherein the sub-bands comprise a first sub-band and one or more other sub-bands;

performing, by the wireless device and in response to the grant:

a first type listen-before-talk (LBT) on the first sub-band; and

performing, after performing of the first type LBT and immediately before transmission on the first sub-band, a second type LBT on each of the one or more other sub-bands, wherein the first type LBT is LBT with back-off, and the second type LBT is LBT without back-off; and

transmitting data on a sub-band of the sub-bands, based on a determination that:

the first type LBT indicates that the first sub-band is clear; and

the second type LBT indicates that each of the one or more other sub-bands are clear.
