BASE STATION APPARATUS, RADIO COMMUNICATION TERMINAL, RADIO COMMUNICATION SYSTEM AND RADIO COMMUNICATION METHOD |
摘要 |
The present invention is designed to provide a base station apparatus, a radio communication terminal, a radio communication system and a radio communication method which can reduce the cost required for MTC terminals when an LTE system is employed in the network domain of a machine communication system. A base station apparatus communicates with a first communication terminal in a first frequency band and also communicates with a second communication terminal in a second frequency band of a narrower bandwidth than the first frequency band, and includes: an allocation control section that allocates an extended downlink control channel which is frequency-division-multiplexed with a downlink shared data channel, in a predetermined frequency region in the second frequency band; and a mapping section that maps a common control signal that is common between the second communication terminals at least, in a common search space of the extended downlink control channel. |

1. A base station apparatus that communicates with a first communication terminal in a first frequency band and that communicates with a second communication terminal in a second frequency band of a narrower bandwidth than the first frequency band, the base station apparatus comprising:
an allocation control section that allocates an extended downlink control channel which is frequency-division-multiplexed with a downlink shared data channel, in a predetermined frequency region in the second frequency band; and a mapping section that maps a common control signal that is common between second communication terminals at least, in a common search space of the extended downlink control channel. |
