A Coexistence Analysis Method to Apply ACLR and ACS between NB-IoT and LTE for Stand-alone Case
In the coexistence scenario of NB-IoT and LTE system,several factors affect the evaluating indicators of system performance.Considering the narrow bandwidth character of NBIoT system,the simulation result would be over-optimistic if the evaluation method about ACLR and ACS in coexistence study of LTE system is still used.In this paper,a new evaluation method about ACLR and ACS is proposed aimed at NB-IoT system,which takes the huge difference of system bandwidth between NB-IoT and LTE system into account.When LTE is the victim system,if the throughput loss does not exceed 5%,LTE and NB-IoT system could coexist.When NB-IoT is the victim system,if the SINR loss is minor compared with the result that without coexistence,NB-IoT and LTE system could coexist.The simulation results show that the NB-IoT system could coexist with LTE system when NB-IoT BS ACS is about 45dB and UE ACLR is in the range of 40~45dB.
