Abstract:
1. A radio communication method for sharing a frequency band between a large cell system including a large cell base station having a relatively large cell size and a small cell system including a small cell base station having a relatively small cell size, comprising: allocating, by the large cell base station, a dedicated resource for the large cell base station and a shared resource for both the large cell base station and the small cell base station dynamically based on information reported from a mobile terminal apparatus carrying out communication in a cell of the large cell base station and information reported from the small cell base station belonging to the large cell base station; broadcasting, from the large cell base station, information on the dedicated resource for the large cell base station and the shared resource to the small cell base station belonging to the large cell base station; and determining, by the small cell base station belong to at least one large cell base station, an assignment resource in a cell of the small cell base station based on the information broadcast from the large cell base station to which the small cell base station belongs on the dedicated resource for the large cell base station and the shared resource.
