Abstract
A wireless device receives a control command for transmission of a random access preamble on a first cell. The wireless device transmits the random access preamble in parallel with a first control packet, a second packet and/or a third packet. The wireless device determines a transmission power for the random access preamble. If a total calculated transmission power exceeds a predefined value, the wireless device reducing or scaling linear transmission power of one or more of the at least one parallel uplink transmission considering a higher priority for the transmission power of the random access preamble.
