報告摘要:

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.

  在過去的一段時間內,計算機領域與通信領域的邊界變得越來越模糊,差距也越來越小,這個變化的原因是主要是由于他們之間具有相似的技術。最常見的一種計算機與通信的融合就是移動邊緣計算(MEC)技術。移動邊緣計算的技術核心是在無線通信網絡的邊緣提供儲存和計算功能。換言之,前者是由無線緩存完成的,后者是由邊緣計算卸載完成的。這次報告的是對于邊緣計算與非正交接入技術的融合做一個全面的介紹。具體的,我們將會介紹一些關于非正交多址接入技術與緩存策略結合的應用。以及對于NOMA-MEC系統中的能量消耗和卸載延遲的分析與優化。最后我們也會總結并討論關于非正交多址接入技術的重要研究挑戰以及未來的發展方向。
