摘要: 在LTE中进行小区间干扰协调的基本前提是区分小区内部/边缘用户。现有的区分方法——RSRP单门限上报机制有诸多弊端,会导致用户位置信息在“小区内部”和“小区边缘”来回切换而形成“乒乓效应”,产生大量不必要的空口信令开销,并对终端的功耗形成很大的负担。鉴于此,提出了一种新的解决方案:RSRP双门限上报机制。新机制的引入解决了上述问题,提供了正确判断用户位置信息的更佳方法。
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.
