论文摘要
在大多数有关非正交多访问(NOMA)的现有作品中,连续的干扰取消(SIC)的解码顺序是前缀的,并基于用户的渠道条件或其服务质量(QOS)要求。最近关于NOMA辅助半质量传输的工作表明,使用更复杂的混合动力SIC方案可以产生重大的性能改善。这封信说明了如何将混合SIC的概念推广并应用于不同的Noma应用程序。我们首先以Noma辅助移动边缘计算(MEC)为例来说明混合SIC的好处,其中提出了延迟和能量最小化的新结果。然后,讨论了通过自适应解码顺序选择及其有希望的应用程序概括混合动力SIC的未来方向。
In most existing works on non-orthogonal multiple access (NOMA), the decoding order of successive interference cancellation (SIC) is prefixed and based on either the users' channel conditions or their quality of service (QoS) requirements. A recent work on NOMA assisted semi-grant-free transmission showed that the use of a more sophisticated hybrid SIC scheme can yield significant performance improvements. This letter illustrates how the concept of hybrid SIC can be generalized and applied to different NOMA applications. We first use NOMA assisted mobile edge computing (MEC) as an example to illustrate the benefits of hybrid SIC, where new results for delay and energy minimization are presented. Then, future directions for generalizing hybrid SIC with adaptive decoding order selection as well as its promising applications are discussed.
