Enabling Ultra-Reliable and Low-Latency Communications in 5G and Beyond Era
报告人：杨楠 副教授 （澳洲国立大学）
报告摘要：The fifth generation (5G) and beyond networks are expected support mission critical ultra-reliable and low-latency communications (URLLC) services. This presentation first introduces the role of URLLC plays in the 5G and beyond era. Then the various sources of end-to-end delay in current wireless networks are described. After this, some promising techniques to support low latency and ultra-high reliability services are envisaged. Motivated by the importance of URLLC, a recent research work on the optimal design of short-packet communications (SPC) in a multiple-input single-output system is presented. Specifically, the optimal allocation of finite resources (e.g. the total transmit power and a finite number of symbol periods) for downlink training, uplink feedback and data transmission is determined to maximise the average data rate. The outcomes of this research work provide a guideline to assist URLLC designers with the fundamental problem of transmit power and symbol period allocation to guarantee the advantage of SPC in practice.
