WIRELESS COMMUNICATION APPARATUS, WIRELESS COMMUNICATION SYSTEM AND WIRELESS COMMUNICATION METHOD

摘要

Use control of a plurality of frequency bands is effectively performed. Radio communication apparatus (1, 2) perform communication by using a plurality of frequency bands. The radio communication apparatus (1) transmits to the radio communication apparatus (2) 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 (2) receives the control message from the radio communication apparatus (1) 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.
