Nowadays, the wireless networks demand high spectral efficiency, reliability and energy efficiency for future needs. In the recent decade, non-orthogonal multiple access (NOMA) with two-user cooperative schemes has received considerable attention for 5G systems. This work demonstrates between the source and far user that not a single link is directly established and we communicate via the near user. We introduce an adaptive power allocation scheme with the combination of cooperative NOMA networks. The preferred scheme selects the best user relay on the basis of performance while the distribution of power allocation coefficients is calculated in order to avoid the wastage of power. This approach also gives a brief discussion on the issue of imperfect successive interference cancellation (SIC) problems with the combination of adaptive scheme.
