1. A method comprising:
receiving, by a wireless device, one or more radio resource control (RRC) messages comprising configuration parameters of a first uplink carrier and a second uplink carrier of an unlicensed cell;
based on switching from the first uplink carrier to the second uplink carrier and a priority class of a listen-before-talk (LBT) procedure for a first transmission of a transport block on the second uplink carrier, determining a contention window to be a minimum contention window of a plurality of contention windows for the LBT procedure; and
transmitting, via the second uplink carrier, the transport block based on the LBT procedure using the contention window.
