Abstract (in Japanese) (See Japanese page) 
(in English) For the past few years, we proposed non-orthogonal multiple access (NOMA) as a promising multiple access scheme for further improvement of spectrum efficiency for LTE enhancements and the 5th generation mobile communications system (5G). Currently, the system performance of NOMA, considering practical assumptions, different deployment scenarios and NOMA specific functionalities, including multi-user pairing, transmit power allocation, and combination with MIMO is being evaluated and discussed in academia, industry, and standardization organizations [5-13]. In addition, the most of existing evaluations for NOMA focus on the full buffer traffic model, which is widely adopted for the evaluation of mobile radio access system. However, further investigations with non-full buffer traffic model are also important to clarify the system performance and enable the support of different types of traffic by NOMA. This paper investigates the system level performance of NOMA with non-full buffer traffic model for different levels of packet arrival rates and sizes. Based on the computer simulations, we show that for non-full buffer case, NOMA can also provide a large performance gain compared to that of OMA even for small packet sizes.
