Abstract (in Japanese) (See Japanese page) 
(in English) This paper investigates a transmission power control (TPC) scheme appropriate for interleave division multiple access (IDMA)-based random access in order to support massive machine-type communications (mMTC) in the fifth generation mobile communication system. In IDMA-based random access, colliding packets are tried to be separately detected by using successive interference canceller (SIC) at the base station receiver to achieve multi-packet reception. Therefore, the TPC in IDMA-based random access should achieve uniform transmission quality within a cell for realizing mMTC, while taking into account its impact on the signal separation capability in SIC process and inter-cell interference levels. This paper proposes a frequency block-dependent fractional TPC where the overall random access bandwidth is divided into two frequency blocks each of which is allocated to either of cell-interior terminals or cell-edge terminals. By coordinating the frequency block usage between neighboring cells, the proposed TPC achieve an inter-cell interference statics appropriate for achieving uniform transmission quality within a cell, while the frequency block-dependent fractional TPC achieves appropriate received power distribution among terminals from the viewpoint of SIC process. Computer simulation results reveals the effectiveness of the proposed method quantitatively.
