Abstract (in Japanese) (See Japanese page) 
(in English) Due to high demand for wireless communication needs, communication cell increases and the available frequency bands decrease. However, cell throughput deteriorates in overcrowded house environment like Japanese apartment. This is reason for Inter-cell interference (ICI) which cause overlapping cell. This paper introduces, analyzing an effective region of two scenarios that increased system throughput in environment which two cells overlapped. As for scenario 1, both access points (APs) suppress ICI each other using spatial domain resource sharing. As for scenario 2, only other AP suppresses ICI using spatial domain resource sharing. In this analysis, we obtained that effect of scenario 1 is high when distance between cells is short and effect of scenario 2 is high when distance between cells is long. Moreover, we obtain that effective region of scenario 1 expends when there are a lot of transmit antenna. In addition, result of evaluating influence of channel estimation error shows that system throughput decreases about 1.6 bit/s/Hz decreases in scenario 1, and about 0.8 bit/s/Hz in scenario 2.
