Practical Performance Analysis of Interference in DSS System

The 5G network is developing rapidly. However, due to spectrum resource limitation, it expected use the ensure high utilization and efficiency, while keeping part of 4G in same band for existing users. Dynamic spectrum-sharing (DSS) technology enables 4G/5G wireless networks coexist scarce resources dynamically allocates band. DSS has been successfully commercialized some countries such as Germany Brazil. complex will introduce intra-frequency interference inter-system, which affect performance. Therefore, we innovatively proposed two mitigation schemes: buffer setting rate matching. Furthermore, have verified practical performance both schemes a commercial first time determine feasibility schemes. From theory, simulation, analysis, can effectively mitigate inter-system introduced by DSS: increasing 60% environment improving user experience architecture.
