報告題目： Impact of NOMA on Convergence of Computing and Communications
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.
