重传误块率优化总结1 误块率优化1.1 外环功控优化一设置较小的ULBLER，通过外环功控的调整，是BLER收敛到1%；增大SIRtarget和最小SIRtarget；增大SIR上调步长。MOD TTYPRABOLPC:RABINDEX=XX, SUBFLOWINDEX=XX, DELAYCLASS=XX, ULBLER=-20, INITSIRTARGET=172, MAXSIRTARGET=222, MINSIRTARGET=172, MAXSIRSTEPUP=1500, MAXSIRSTEPDN=100, SIRSTEPUPSIZEFORBLER=500, SIRSTEPDOWNSIZEFORBLER=10;（TTYPRABBASIC中CNDOMAINID=PS_DOMAIN，MAXBITRATE大于8000的RABINDEX均修改）现网均已执行，对误块率提升具有一定效果，误块率差小区个数未有明显提升。1.2 外环功控优化二进一步降低ULBLER，收敛BLERMOD TTYPRABOLPC:RABINDEX=XX, SUBFLOWINDEX=XX, DELAYCLASS=XX, ULBLER=-23（TTYPRABBASIC中CNDOMAINID=PS_DOMAIN，MAXBITRATE大于8000的RABINDEX均修改）现网均已执行，对误块率提升具有一定效果，误块率差小区个数未有明显提升。1.3 小区场景化调整1.3.1 增加场景OLPC参数（RNC级）ADD TOLPCPARAS: OLPCSTRAIDX=0, OLPCSTRANAME=PS BLER提升策略, ULBLER=-25, INITSIRTARGET=192, MAXSIRTARGET=252, MINSIRTARGET=192, SIRADJUSTPERIOD=10, MAXSIRSTEPUP=1500, MAXSIRSTEPDN=100, SIRSTEPUPSIZEFORBLER=1000, SIRSTEPDOWNSIZEFORBLER=10;ADD TOLPCPARAS: OLPCSTRAIDX=1, OLPCSTRANAME=AMR BLER提升策略, ULBLER=-20, INITSIRTARGET=162, MAXSIRTARGET=242, MINSIRTARGET=142, SIRADJUSTPERIOD=40, MAXSIRSTEPUP=500, MAXSIRSTEPDN=200, SIRSTEPUPSIZEFORBLER=100, SIRSTEPDOWNSIZEFORBLER=100;ADD TOLPCPARAS: OLPCSTRAIDX=2, OLPCSTRANAME=VP BLER提升策略, ULBLER=-30, INITSIRTARGET=182, MAXSIRTARGET=242, MINSIRTARGET=162, SIRADJUSTPERIOD=40, MAXSIRSTEPUP=1500, MAXSIRSTEPDN=100, SIRSTEPUPSIZEFORBLER=800, SIRSTEPDOWNSIZEFORBLER=10;1.3.2 增加OLPC场景配置（RNC级）ADD TOLPCSCENE: CELLSCENE=SPECIAL_SCENE1, AMROLPCSTRAIDX=1, VPOLPCSTRAIDX=2, PSBE16KOLPCSTRAIDX=0, PSBE32KOLPCSTRAIDX=0, PSBE64KOLPCSTRAIDX=0, PSBE128KOLPCSTRAIDX=0, PSBE128KEXOLPCSTRAIDX=0, PSLOWSPEEDSTREAMOLPCSTRAIDX=0, PSHISPEEDSTREAMOLPCSTRAIDX=0;1.3.3 增加小区场景MOD TCELL: CELLID=XX, CELLSCENE=SPECIAL_SCENE1;已对误块率差高频TOP30小区进行调整，误块率及频次有一定改善，今日计划对第二批80个小区进行调整。2 重传率优化针对RLC重传率高的小区，进行外环功控优化:MOD HSPACTRL: LOCALCELLEID=xxx, CARRIERRESID=xxx, CQIOLB=55, CQIO
