A wireless device may receive configuration parameters of an unlicensed cell for uplink transmissions of data of logical channels. Each of the logical channels may be associated with a logical channel priority and a quality of service indicator. The wireless device may receive an uplink grant, for the unlicensed cell, indicating uplink resources and a type of listen-before-talk (LBT). The wireless device may allocate first uplink resources of the uplink resources for first data of a first logical channel, of the logical channels, with a first LBT priority number corresponding to a first quality of service indicator for the first logical channel. The wireless device may allocate remaining uplink resources of the uplink resources for second data of a second logical channel, of the logical channels, with a second LBT priority number lower than the first LBT priority number. The wireless device may perform an LBT procedure based on the type of LBT. The wireless device may transmit the first data and the second data via the uplink resources.
