Abstract (in Japanese) (See Japanese page) 
(in English) Non-orthogonal multiple access (NOMA) has been recognized as a promising multiple access candidate for a 5G network. In this paper, we first discuss NOMA model with 2 users served by a receiver based on parallel interference cancellation (PIC) instead of successive interference cancellation (SIC). The reason for motivation towards PIC is it’s fastness by detecting and cancelling all interference at the same time. Moreover, PIC is not power sensitive like SIC so if base station allocates similar power for different user then PIC may be better alternatives. And we calculate a SINR of SIC and PIC by using threshold defined for interference cancellation. As a trade-off factor, complexity, can be minimized in multistage PIC receiver based on difference of the estimated bits in two consecutive stages of interference cancellation. Furthermore, we proposed a new scheme called dynamic power allocation scheme for different users in cell edge and cell center. Simulation results shows that the proposed dynamic power allocation strategies in PIC based NOMA can provide a considerable user’s fairness and performance improvement compared with the existing methods.
