2016年4月19日，Lancaster大学丁志国教授应戴旭初教授邀请做了一场题为“NOMA – A Paradigm Shift for Multiple Access in 5G”的学术报告。报告会由徐正元教授主持，共50余名师生参加。此次报告会得到了“中科院无线光电通信重点实验室系列讲座”的支持，由中科大信息科学技术学院、中科院无线光电通信重点实验室承办。
丁志国教授指出下一代网络随着移动数据和多媒体交通的快速发展，5G移动网中的多址接入技术已成为一项新兴的研究课题。其中非正交多址接入技术（NOMA）引起了广泛的关注。在报告中，丁志国教授介绍了NOMA的关键思路是从功率域进行多址接入，这意味着多用户能在相同的时间、频率和扩频码同时接受服务。此外NOMA并非使用注水功率分配算法，而是为信道条件差的用户提供更多的能量，目前工业实践也表明NOMA技术能显著提升移动网络的频谱效率。基于这样的优越性能，NOMA已被提出用于3GPP-LTE系统中的下行链路。最后，丁志国教授介绍了NOMA的一些应用前景，包括NOMA与认知无线电交互，NOMA与MIMO相结合等。报告结束后，丁志国教授与在座的老师和同学们进行了深入的交流，对NOMA的理论技术及应用等相关内容展开了热烈的讨论，达到了学术交流迸发思想的目的。
