Abstract
Low latency communication has attracted much interest in recent years due to the emergence of new types of delay-sensitive applications. Ultra-Reliable and Low-Latency Communication (URLLC) is also considered as one of the important use-cases in 5G cellular system. Traditional wireless communication system is usually optimized for high data throughput, but cannot satisfy the requirement of strict latency threshold. Semi-persistent scheduling and TTI shortening are two methods to address this problem. We implemented these methods by making modification based on OpenAirInterface framework, and build up a realistic cellular network system using software-defined radio technology. Experimental results show a dramatic latency reduction comparing with the baseline LTE scheme. By integrating these effective methods, we implemented a practical wireless communication system that can provide low latency transmission service.
