EMC Provision Method of LTE-800 Networks and Air Traffic Control Radars Based on Mechanism of Cell Radius Management for LTE Base Stations

摘要

Geographical separation and frequency separation between a source and a victim of harmful interferences are two main methods for ensuring electromagnetic compatibility (EMC). Geographical separation was chosen as the main method of sharing in 800 MHz band between user terminal (UE) of LTE-800 and air traffic control radars (ATC radars) since frequency separation is not possible in case of co-channel LTE and ATC Radar operations. The proposed interference protection method for ATC Radar receivers experiencing interference from UE transmitters of LTE-800 networks is based on providing separation distance between ATC Radar and UE. Ensuring of separation distance is implemented by the management and limiting of cell radius of LTE base stations located near ATC Radars. The method was proved by simulation tests and can provide a solution to the EMC issue by LTE base station parameter management which defines cell radius in LTE-800.
