A Performance Study of Dynamic Spectrum Sharing in FDD LTE and NR
The application and performance of FDD LTE/NR Dynamic Spectrum Sharing technology in 5G networks is investigated in the study,which focuses on the 1.8 GHz band and conducts experimental tests in an indoor environment.Using drive tests and CQT methods,the study compares network performance under LTE-only,NR-only,and DSS modes.The performance of dynamic spectrum sharing is validated from multiple dimensions,including RSRP,SINR,MCS,occupied RB numbers,and throughput.Results show that while DSS technology improves spectrum utilization,it impacts both LTE and NR performance.LTE performance loss ranges from 3％to 8％,while NR performance loss is between 10％and 22％.DSS technology can flexibly adjust resources based on LTE and NR service demands,and in the context of increasing 5G terminal penetration and network development,can effectively enhance network capacity and spectral efficiency.
