Zusammenfassung:PROBLEM TO BE SOLVED: To enable flexible switching between multicast transmission using MBSFN sub frame and inter-cell interference adjustment without degrading the resource utilization efficiency.SOLUTION: On the basis of the presence or absence of transmission data in each first area constructed by at least some sub frames of plural MBSFN (Multicast-Broadcast Single Frequency Network) sub frames, a transmission data determining part 107 determines which one of a first sub frame to be subjected to multicast transmission and a second sub frame to be subjected to inter-cell interference adjustment is applied to the first area. A radio communication unit 109 executes transmission processing on the first area according to the determination result.SELECTED DRAWING: Figure 4 【課題】リソース利用効率を低下させることなく、MBSFNサブフレームを用いたマルチキャスト送信とセル間干渉調整とを柔軟に切り替えること。【解決手段】送信データ判定部107は、複数のMBSFN(Multicast-Broadcast Single Frequency Network)サブフレームのうちの少なくとも一部のサブフレームで構成される第1の領域の各々における送信データの有無に基づいて、第1の領域を、マルチキャスト送信を行う第1のサブフレーム又はセル間干渉調整を行う第2のサブフレームの何れとして使用するかを判定する。無線通信IF部109は、判定結果に従って、第1の領域における送信処理を行う。【選択図】図4
