A wireless device receives a control command for transmission of a random access preamble on a first cell. A first packet is scheduled for parallel uplink transmission with the random access preamble transmission. The wireless device transmits the random access preamble. The wireless device transmits the first packet in parallel with the random access preamble if the random access preamble and the first packet are scheduled for transmission in different cell groups and the wireless device has sufficient power to transmit the first packet in parallel with the preamble.
