论文摘要
非正交多访问（NOMA）的关键思想是同时和频率同时为多个用户服务，这可能导致过度多次访问干扰。作为NOMA系统的关键组成部分，连续的干扰取消（SIC）是对抗这种多元访问干扰的关键，并且在这封信中专注于SIC解码顺序选择方案。特别是，分别讨论了基于用户渠道状态信息（CSI）和用户服务质量（QOS）的SIC解码顺序。说明了这两种方法的局限性，然后将最近提出的方案称为Hybrid SIC，该方案会动态调整SIC解码顺序，并显示出令人惊讶的性能改善，而传统的SIC解码顺序选择方案则无法实现。
The key idea of non-orthogonal multiple access (NOMA) is to serve multiple users simultaneously at the same time and frequency, which can result in excessive multiple-access interference. As a crucial component of NOMA systems, successive interference cancelation (SIC) is key to combating this multiple-access interference, and is focused on in this letter, where an overview of SIC decoding order selection schemes is provided. In particular, selecting the SIC decoding order based on the users' channel state information (CSI) and the users' quality of service (QoS), respectively, is discussed. The limitations of these two approaches are illustrated, and then a recently proposed scheme, termed hybrid SIC, which dynamically adapts the SIC decoding order is presented and shown to achieve a surprising performance improvement that cannot be realized by the conventional SIC decoding order selection schemes individually.
