Patent abstract

A wireless device receives a control command to transmit a random access preamble on a second carrier. The wireless device repeatedly transmits the random access preamble until a random access response corresponding to the random access preamble is received or a predefined number of transmissions is reached. If the predefined number of transmissions is reached without receiving the random access response, the wireless device keeps an RRC connection with the base station active.
