  Abstract

Recently, a newly deployed communications paradigm, cooperative communications, such as decode-and-forward (DF) relaying, have been one of promising candidates for the fifth generation (5G) mobile network. Another strong candidate for 5G radio access is non-orthogonal multiple access (NOMA). In NOMA, successive interference cancellation (SIC) is performed on the strong channel user to compensate for small power allocation. Then as the by-product of SIC, DF relaying can be easily implemented in NOMA. This paper compares NOMA to DF NOMA. We show how much DF NOMA is better than NOMA. This DF NOMA gain is due to the use of the additional time slot resource. In order to compare the two schemes fairly, we assume that NOMA retransmits the information one more time with the additional time slot resource. The contributions of this paper, opposed to the existing researches based on the channel capacity, is that the analytical expressions for the bit error rate (BER) performance are derived and with the use of such analytical expressions, the performance comparisons can be made intensively and flexibly for various system scenarios and channel conditions under the fair conditions.
