Radio communication system, high-power base station, low-power base station, and communication control method |
摘要 |
A radio communication system (1) includes a pico-cell base station (PeNB) which is located in the communication area of a macro-cell base station (MeNB) and the transmission power of which is lower than that of the macro-cell base station (MeNB). For radio resources that can be used as PDSCH, a resource division ratio that is a ratio between unusable PDSCH resources, which cannot be used by the macro-cell base station (MeNB), and usable PDSCH resources, which can be used by the macro-cell base station (MeNB), is decided, and a radio resource is allocated, out of the usable PDSCH resources defined in accordance with the decided resource division ratio, to a radio terminal that is to connect to the macro-cell base station (MeNB). The resource division ratio is decided based on the traffic load of each base station. |

1. A radio communication system comprising a first base station and a second base station,
the first base station comprising a processor configured to set normal subframes and specific subframes among a plurality of subframes used for a downlink, wherein a transmission power of the specific subframes is limited to low compared with the normal subframes, and the processor changes a setting pattern of the normal subframes and the specific subframes among the plurality of subframes on the basis of information on a load of the second base station, wherein the information on the load of the second base station is acquired via an X2 interface and indicates a usage rate of resource blocks in the second base station. |
