Abstract
A Base station transmits a control command for transmission of a random access preamble on a first cell if the base station determines radio resources of the first cell are required for transmission of a portion of data and that the first cell requires a different uplink timing from all currently activated cells of the wireless device. The base station transmits at least one control packet for providing transport format information and resource allocation information for transmission of a plurality of packets of the data to be transmitted on a first data channel of the first cell.
