BASE STATION AND RADIO COMMUNICATION METHOD |
| 摘要 |
Even when a downlink radio traffic volume is larger than an uplink radio traffic volume in a radio communication system, but uplink resources are redundant in a related art radio communication system, free uplink resources could not be sufficiently utilized. In a base station having a cellular unit that performs cellular communication with a terminal, and a D2D unit that performs communication with the terminal through a device-to-device communication system, when the downlink radio resources get tight, and the uplink radio resources are redundant, the D2D unit of the base station conducts transmission and reception with the terminal with the use of the uplink radio resources. |

1. A base station, comprising:
a cellular unit that performs cellular communication with a terminal; a D2D unit that performs communication with the terminal through a device-to-device communication system; and a control unit that determines a usage status of downlink radio resources and a usage status of uplink radio resources, wherein if the downlink radio resources get tight, and the uplink radio resources are redundant as a result of the determination, the D2D unit conducts transmission and reception with the terminal with the use of the uplink radio resources. |
