Abstract
A user apparatus includes a transmission unit for transmitting a signal related to a random access procedure in a serving cell; a reception unit for receiving a signal related to the random access procedure in the serving cell; and a control unit for determining a carrier to be used for the random access procedure, the carrier being configured to the serving cell. The control unit determines whether a first carrier is configured to the serving cell, determines whether the first carrier of the serving cell is supported when the first carrier is configured to the serving cell, and determines to use the first carrier for the random access procedure when the first carrier of the serving cell is supported. An operation of determining the carrier to be used for the random access procedure is performed in at least one of a MAC layer and an RRC layer.
