A wireless device may receive at least one message comprising: first configuration parameters of a first bandwidth part, and second configuration parameters of a second bandwidth part. The second configuration parameters may comprise a scheduling request configuration indicating scheduling request resources for a logical channel. A scheduling request may be triggered in response to data becoming available for the logical channel. A random access process may be started in response to a valid scheduling request resource for the logical channel not being available on the first bandwidth part. A downlink control information may be received. The downlink control information may indicate switching from the first bandwidth part to the second bandwidth part. In response to the scheduling request resources being available on the second bandwidth part: the random access process may be cancelled, and a scheduling request signal may be transmitted via the scheduling request resources.
