Abstract
5G (The Fifth Generation) mobile networks are expected to achieve significant improvements in several key performance metrics, where low latency is urgently needed by many emerging IoT businesses, such as remote surgery, augmented reality, haptic Internet and IoV. In this paper, a multi-user space - time modulation scheme for super - reliable low - delay communication is studied. Based on 5 g technology support in the new wireless frame structure of the coexistence of a variety of business, for business and eMBB URLLC business coexist in the data transmission of conduct the thorough research to the downlink scheduling mechanism, this mechanism allows URLLC business data to grab some data are transmitted eMBB wireless resources, occupied in eMBB business to transmit data on punch to URLLC business can be scheduled in time, to meet the requirements of URLLC business ultra low delay.
