Building on reinforcement learning techniques and, more precisely, on multi-armed bandits (MAB), we propose a novel adaptive NOMA scheme that optimally tunes which user should perform successive interference cancellation (SIC) jointly with the power allocation at the BS. Remarkably, our proposed scheme requires only a single bit (ACK-type) of feedback from each user and is still able to outperform OMA, as demonstrated by the numerical results in many settings of interest including stochastic and even non-stationary (adversarial) ones.Show less >
