which is expressed as the ratio of the user … EE, also preserves fairness among all users in the …

… -user assignment algorithms (SUAAs) for the downlink NOMA system to enhance the spectral
efficiency, the fairness, the data rate of weak users, … In [13] a virtual-UP is implemented to …

… A lossless NOMA implementation without SIC was proposed in this study. To this end, CSC
and correlated nonSIC decoding were proposed, and the conditional achievable sum rate …

… and two NOMA users in each C-NOMA pair. In phase I, ie, NOMA phase, BS transmits a
NOMA frame of … To implement the NOMA scheme, users are grouped into some clusters. While …

… NOMA downlink transmission in an underlaying cognitive radio network. The worst-case

… First, we focus on enhancing user fairness only within each NOMA sub-group. Specifically,
the BS needs to distribute the power resources between the two users within the sub-groups …
