Coexistence Analysis Between NB-IoT and LTE-R/Broadcasting Service System in 450MHz-470MHz Band

Based on the 450-470MHz interference coexistence scenario, this paper uses deterministic analysis method to analyze the coexistence of 458-460MHz/468-470MHz NB-IoT system and 453-458MHz /463-468MHz LTE-R system, the coexistence of 468-470MHz NB-IoT system and 470-478MHz Broadcasting Service System, and obtains the corresponding isolation requirements. On the basis of comprehensive analysis, the interference avoidance measures for the coexistence of the system are proposed, which can provide reference for the frequency planning of 450-470MHz band.
