Abstract
A wireless device establishes a first signaling bearer with a base station on a primary cell. The establishment of the signaling bearer comprises the wireless device receiving a control message from the base station on the primary cell in a plurality of cells comprising the primary cell and at least one secondary cell. The wireless device transmits radio capability parameters to the base station on the first signaling bearer on the primary cell. The radio capability parameters comprise at least one parameter indicating whether the wireless device supports a timing advance groups.
