Non orthogonal multiple access (NOMA) and mobile edge computing (MEC) are evolving as key enablers for fifth generation (5G) networks as this combination can provide high spectral efficiency, improved quality-of-service (QoS), and lower latency. This letter aims to minimize the transaction time difference of two NOMA paired users offloading data to MEC servers by optimizing their transmission powers and computational resources of severs using a successive convex approximation method. The equalization of transaction time for paired users reduces the wastage of both frequency and computational resources, and improves effective throughput of the system to 19% on average.

最小化基于 NOMA 的移动边缘计算的事务时间差异

非正交多址 (NOMA) 和移动边缘计算 (MEC) 正在发展成为第五代 (5G) 网络的关键推动因素，因为这种组合可以提供高频谱效率、改进的服务质量 (QoS) 和更低的延迟。这封信旨在通过使用逐次凸逼近方法优化服务器的传输功率和计算资源来最小化两个 NOMA 配对用户将数据卸载到 MEC 服务器的交易时间差异。配对用户交易时间的均衡化减少了频率和计算资源的浪费，将系统的有效吞吐量平均提高到19%。
