报告摘要:

During the past decades, the boundary between computing and communications has become more and more indistinguishable due to their used common technologies, where mobile edge computing (MEC) is one of the latest examples for such convergence of computing and communications. The key feature of MEC is to provide storage and computing functionalities at the edge of wireless communication networks, where the former is realized by wireless caching and the latter is accomplished by MEC offloading. This talk is to provide a brief overview for the impact of an emerging communication technique, non-orthogonal multiple access (NOMA), on wireless caching and MEC offloading. Particularly, we will show a few NOMA assisted caching strategies which can improve the hit probability in a spectrally efficient way. In addition, the fundamental limits of NOMA-MEC are illustrated, where its energy consumption and offloading delay are analyzed and optimized. Finally, the study is concluded with a discussion of important research challenges and promising future directions in NOMA.

  在过去的一段时间内,计算机领域与通信领域的边界变得越来越模糊,差距也越来越小,这个变化的原因是主要是由于他们之间具有相似的技术。最常见的一种计算机与通信的融合就是移动边缘计算(MEC)技术。移动边缘计算的技术核心是在无线通信网络的边缘提供储存和计算功能。换言之,前者是由无线缓存完成的,后者是由边缘计算卸载完成的。这次报告的是对于边缘计算与非正交接入技术的融合做一个全面的介绍。具体的,我们将会介绍一些关于非正交多址接入技术与缓存策略结合的应用。以及对于NOMA-MEC系统中的能量消耗和卸载延迟的分析与优化。最后我们也会总结并讨论关于非正交多址接入技术的重要研究挑战以及未来的发展方向。
