A wireless device receives RRC message(s) comprising: a first maximum value for a preamble transmission counter; and a second maximum value for a second counter. The second maximum value is different from the first maximum value. A control order initiating a random access procedure on a first unlicensed cell is received. A listen-before-talk (LBT) procedure for transmission of a preamble for the random access procedure is performed. Based on the LBT procedure indicating an LBT failure for transmission of the preamble for the random access procedure: a value of the preamble transmission counter is keep the same; and a value of the second counter based on the LBT failure is incremented. The preamble transmission counter counts a number of preamble transmissions. The random access procedure is cancelled based on either the preamble transmission counter reaching the first maximum value or the second counter reaching the second maximum value.
