RADIO COMMUNICATION APPARATUS, RADIO COMMUNICATION SYSTEM, AND RADIO COMMUNICATION METHOD

摘要

Radio communication apparatus perform communication by using a plurality of frequency bands. The radio communication apparatus transmits to the radio communication apparatus by using a first frequency band a control message including identification information indicating a second frequency band different from the first frequency band during a random access procedure. The radio communication apparatus receives the control message from the radio communication apparatus by using the first frequency band and performs data communication by using the second frequency band indicated by the identification information included in the control message.
