Balanced-QoS power allocation schemes for nNOMA in the finite blocklength regime

Non-orthogonal multiple Access (NOMA) technology may find its way into sixth-generation (6G) mobile networks thanks to its ability to support heterogeneous services and improve spectral efficiency. In this context, shorter packet usage is imperative for reducing latency and strengthening reliability...
