• receiving, by the wireless device, a downlink control information (DCI) comprising an uplink grant for the LAA cell, the uplink grant comprising transmission parameters comprising:
• uplink resources for one or more transport blocks (TBs);
• and
• an indication of a first listen-before-talk (LBT) priority class number;
• selecting, by the wireless device, one or more first logical channels of the plurality of logical channels with an LBT priority class number equal to the first LBT priority class number;
• performing, by the wireless device, a first allocation of first uplink resources of the uplink resources to the one or more first logical channels;
• performing, by the wireless device, a second allocation of at least a portion of remaining uplink resources of the uplink resources to one or more second logical channels of the plurality of logical channels with one or more LBT priority class numbers lower than the first LBT priority class number;
