A wireless device receives, one or more messages from a base station. The one or more messages indicate a first scheduling request (SR) resource corresponding to a first logical channel. A first SR is triggered in response to data of the first logical channel becoming available for transmission to the base station. A second SR is triggered in response to data of a second logical channel becoming available for transmission to the base station. when no valid SR resource is being configured for the second SR: a random access procedure is initiated; and the second SR is canceled and the first SR is kept pending. The first SR is transmitted to the base station via the first SR resource in response to the triggering of the first SR. An uplink grant for transmission of a transport block is received.
