报告题目(Title):Radio access network slicing (RAN Slicing) for 5G and beyond


The next generation wireless communication (5G) and beyond will enable fully mobile and connected society, which is required to support a variety of very diverse user cases in terms of throughput, latency, reliability, availability and scalability. Three main communication scenarios have been identified by 3GPP with each having huge potential applications, i.e., enhanced mobile broadband (eMBB) (e.g., supporting mobile HD movie), massive machine type communications (mMTC) (e.g., supporting internet of things communications), and ultra reliable low latency communications (URLLC) (e.g., supporting vehicular to vehicular or virtual reality communications). As a solution to support all scenarios, network slicing enables design, deployment, customization, and optimization of different network slices on a common infrastructure. From the physical layer/RAN perspective, due to the extreme diverse requirement among services and use cases, the service configurations in different resource slices may be significantly different from both base band (BB) and radio frequency (RF) aspects. Such a heterogeneous multi-service system may fundamentally affect the widely used transceiver architecture, algorithms, signal processing procedures and implementations in the traditional single-service system. In this talk, we will introduce the basis idea of the a physical layer network slicing (PNS), framework and analysis, some 5G communication scenarios and potential implementations will be also discussed.


Dr. Lei Zhang received his B.Eng. M.Sc. degrees from the Northwestern Polytechnic University (NWPU), Xi'an, China, and Ph.D. from the University of Sheffield. He was a research engineer in Huawei Communication Technology Laboratory (CT Lab) and a research fellow in the 5G Innovation Centre (5GIC), Institute of Communications (ICS), University of Surrey, U.K. He is now a Lecturer (Assistant Professor) in the School of Engineering, University of Glasgow, UK.  He has more than 10 years’ work experience on 3G/4G/5G wireless communications research. He had been broadly involved into EU FP7 IJOIN project, 5GIC project, EPSRC project, industry collaboration research project, China National Science and Technology Major Project and also contributed to 3GPP RAN1 standardizations. He held 16 international patents on wireless communication systems and applications. He has published 25 top quality journal papers and 3 book chapters.

Dr Lei Zhang’s research interests broadly lie in the Communications and Array Signal Processing. Recently, his research focuses on physical layer and MAC layer communication systems with potential applications to 5G scenarios: enhanced Mobile Broadband (eMBB), massive Machine Type Communications (mMTC) to Ultra-Reliable and Low Latency Communications (URLLC). Specifically, Physical layer network slicing (RAN slicing), new air interface design (waveform, frame structure, etc.), Internet of Things (IoT), multi-antenna signal processing, cloud radio access networks, massive MIMO systems, Full-duplex, etc.
