Abstract: In the study of ICIC (inter-cell interference coordination）of LTE，the basic foundation is to distinguish interior users from exterior users. The existing method, RSRP single-threshold reporting mechanism, will cause UE position information to be switched between “interior UE” and “cell edge UE”. This Ping-pong effect can cause a lot of unnecessary signaling and load a heavy burden on UE battery consumption. Based on this, a new method is proposed, which is RSRP double-thresholds reporting mechanism. The new method can solve the problems above, so as to provide a more efficient way to judge the UE position.
