报告摘要：Future 5G IoT networks are expected to be the ultra-dense wireless networks aiming at providing a wide-range services, from high-rate continuous applications to low-rate sporadic short-burst services. Explicitly, radio access for sporadic short-burst IoT traffic based on the traditional multiple-access schemes used, such as, in LTE/LTE-A, is inefficient, due to the resultant high overhead ratio. Therefore, in this talk, we first address the main challenges of radio access in 5G massive IoT networks. Then, in order to reduce the overhead ratio, the problems and technical solutions for grant-free massive access are explored. Furthermore, we introduce two types of low-complexity detection schemes that are efficient for operation in heavily loaded IoT systems. We emphasise the advantages, disadvantages and challenges for the practical implementation of these optional techniques. We conclude the talk by discussing some open problems for future research.
