The increasing small data package transmission from the prosperously growing number of deployed networks, connected devices and multi-media applications has triggered the study of new technologies to have optimized spectrum utilization. Non-orthogonal multiple access (NoMA) has been proposed in both academic and industry as a promising technology to achieve such purpose by providing the ability to serve massive user equipment (UE) and exploit the properties of small data transmission. In addition to the intra-cell multi-user interference handling, an evolved operation of a NoMA scheme with bit-level interleaving and symbol level grid mapping is proposed in this paper to solve its major issue in practical communication systems: inter-cell interference (ICI). Theoretical analysis and simulation evaluations are provided and the results show that the proposed method can effectively mitigate the inter-cell interference, and hardware test-bed also proves robust BLER performance could be achieved under multi-cell scenarios.
