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

摘要

A radio communication apparatus that performs communication with another radio communication apparatus by using a plurality of pairs of a downlink frequency band and an uplink frequency band, the apparatus includes: a receiving unit configured to receive a control message by using a downlink frequency band of a first pair among downlink frequency bands of the pairs during a random access procedure to said another radio communication apparatus, the control message including identification information indicating use of an uplink frequency band of a second pair different from the first pair, the downlink frequency band of the first pair being monitored for control messages by the radio communication apparatus; and a control unit configured to control the radio communication apparatus to perform data communication with said another radio communication apparatus by using the uplink frequency band of the second pair indicated by the identification information included in the control message.

1. A radio communication apparatus that performs communication with another radio communication apparatus by using a plurality of frequency bands, the radio communication apparatus comprising:
a receiving unit configured to receive a control message by using a first frequency band during a random access procedure to said another radio communication apparatus, the control message including identification information indicating a second frequency band different from the first frequency band at a predetermined position that does not change even when a bandwidth of the second frequency band is different from the first frequency band; and a control unit configured to control the radio communication apparatus to perform data communication with said another radio communication apparatus by using the second frequency band indicated by the identification information included at the predetermined position of the control message.
