Performance Analysis of Uplink-dominate Frame Structure

Vertical industries generate different traffic types that impose very diverse and extreme requirements on the network. Currently vendors and operators had been gradually noticed in the need to support more advanced applications with stricter reliability, throughput and latency requirements, such as XR, vision-based factory detection, remote medical service and live video. How to improve the UL data rate to meet the strict requirements for newly applications is an important step for network evolution to meet the commercial needs. 5G frame structures have the ability to provide sufficient flexibility for diverse use cases, deployments, spectrums and device capabilities. Currently, the frame structure in commercial network is DL-dominate. in the view of the fact that several use cases in vertical industries are UL unbalanced, this paper analysis a new uplink dominate frame structure in terms of latency and throughput. The simulation results show the uplink performance can be significantly improved by uplink dominate frame structure.
