Delivering more to cell edge via joint multi‐cell non‐orthogonal multiple access and traffic offloading

We consider leveraging the joint potential of non-orthogonal multiple access (NOMA) and traffic offloading to benefit cell-edge users in multi-cell scenarios. formulate edge-driven throughput maximisation problem where both decision resource allocation are be optimised, accounting for impact inter-cell interference on decoding order NOMA. The is not given constants as it influenced by allocation. Therefore known a priori. explore decomposing into two subproblems. By analysis structural properties, we derive algorithm modules which interact iteratively reciprocity, forming overall algorithm. Numerical results show that proposed scheme considerably improves throughput, compared with conventional orthogonal without offloading.
