Reduce TTI=10ms to 2ms


#1

Dears,

I reduce the TTI from 10 ms to 2ms and there is a huge improvement in HSUPA throughput but unfortunately, there is an increase in PS call drop, kindly your advise to find out how to decrease the PS call drop. we are using Alcatel vendor.

Br,
Hasan

hi, you can manage it by optimized the SIR target from prev through UL BLER and changed it based on UE Tx measurement, its recommended for UE R8 version or above. it will enhanced ratio DPCCH to DPDCH.
