1. A user apparatus comprising:
a processor configured to:
determine to use an SUL (Supplementary Uplink) for a random access procedure in a case where the SUL is configured to a serving cell and where the SUL is supported, and
determine whether at least one spectrum emission in a maximum power list for a supported frequency band is supported;
a transmitter configured to transmit a signal related to a random access procedure in a serving cell; and
a receiver configured to receive a signal for the signal related to the random access procedure in the serving cell,
wherein an operation of determining the carrier to be used for the random access procedure is performed in at least one of a MAC (Media Access Control) layer and an RRC (Radio Resource Control) layer.
