Abstract: Non-Orthogonal Multiple Access (NOMA) is
known as one of the promising techniques in the fifth generation
of wireless communication. The classification of users in (NOMA)
is based on power, while it is based on time, frequency and code
in Orthogonal Multiple Access (OMA). In this study the
downlink NOMA includes two users, one strong and one weak.
The comparison of NOMA and OMA properties shows a range of
Power Allocation Factors (PAF) for the two users within which
NOMA properties have proved to be better than OMA. It was
also shown that the achieved PAF is a function of channel gains
of two users. Then, the coverage region is defined for multiple
access channel; and by considering the Base Station (BS) as a
fixed one in the center of the cell, the coverage region for both
NOMA and OMA is calculated. The theoretical and analytical
results show that the achieved coverage region of NOMA for both
weak and strong users has been increased compared to OMA.
