LTE重选切换参数优化（FDD）

时间内新小区比服务小区排列更前 2) UE 在当前服务小区的驻留时间超过 1秒涉及参数: qHyst LNCEL ; 0dB (0), …,24dB (15) ;默认值“-” qOffsetCell IAFIM ; -24 dB (0), …,24 dB (30); -; 默认值“0 dB(15) ” tReselEutr LNCEL ;0… 7s; 步长“ 1s”;默认值“–” 2.2.3.2 异频重选异频重选(同优先级) 异频重选时会增加一个频率偏移量( frequency offset ) ,加强重选的可控性。小区重选准则( Qmeas,s & Qmeas,n 基于 RSRP ) Rs = Qmeas,s + Qhyst Rn = Qmeas,n – Qoffset ( qOffCell ) Qoffset = qOffCell,n + Qoffsetfrequency ( qOffFrq ) Rn > Rs 时“ cell reselection 涉及参数: qOffCell Cell specific offset ; IRFIM; -24..24; 1;- qOffFrq Frequency specific offset for equal priority EUTRAN frequencies ; IRFIM; -24..24; 2; 0dB qHyst LNCEL ; 0dB (0), …,24dB (15) ;默认值“-” tReselEutr LNCEL ;0… 7s; 步长“ 1s”;默认值“–”异频重选(高优先级) 邻小区层级为高优先级时只要满足下面准则且持续时间 Treselection ( interTResEut ) 即可。小区重选准备( Qrxlevmeas 基于 RSRP ): SnonServingCell > Threshx,high
