| 摘 要： | 该文研究了多小区混合非正交多址接入(MC-hybrid NOMA)网络的资源分配。为满足异构用户的服务体验，以最大化全网综合平均意见评分(MOS)累加和为目标，考虑基站选择、信道接入和功率资源分配的联合优化问题，该文提出一种用户、基站和信道3方的2阶段转移匹配算法，并根据用户MOS进行子信道功率优化。仿真结果表明所提多小区混合NOMA网络资源分配方案能有效提升全网用户服务体验和公平性。

| Abstract: | Resource allocation in Multi-Cell hybrid Non-Orthogonal Multiple Access-orthogonal multiple access (MC-hybrid NOMA) networks is studied in this paper. To satisfy the Quality of Experience (QoE) of different service types of users, an algorithm joint user-BS association, sub-channel assignment and power allocation is proposed to maximize the sum Mean Opinion Scores (MOSs) of users in the networks. A low-complexity two-step approach based on matching game theory and developed power allocation strategy based on QoE proportional fairness are proposed. Simulation results demonstrate that the proposed algorithm can effectively improve the system performance and fairness. |
