SE Improvement on 4G Huawei Network

In This post I would like to share about SE(Spectrum efficiency,Spectral efficiency, or bandwidth efficiency)  improvement on 4G Huawei Network.SE can be defined by the net of data rate that can be transmitted over a given bandwidth in a specific communication system. SE is measured by bit/s/Hz or maximum throughput divided by the bandwidth. Here area some tips to improve SE on 4G LTE Huawei Network.

1. Fix Hardware issue
2. Fix Transmission issue
3. Fix Cross feeder issue

4. RET port balancing, make sure tilt setting port A and B are same
5. Optimize Coverage issue
6. Parameter Optimization:
- EPF Capacity Factor
- TA Time Implementation : TimeAlignmentTimer,P0NominalPUCCH,PucchPcTargetSinrOffset,PucchPcDtxSinrSwitch,Format1ChAllocMode
- Implement SE Pack Parameter: SrbProbeSchSwitch,NearPointUeOptPUSCHSwitch,UlSmallRBSpectralEffOptSw,PdcchOutLoopAdjBaseStep,P0NominalPUCCH,CqiAdjStep

Here are some case SE improvement

-SE improved after RET port balancing

Found different setting RET on site E_CIGUNTING_SRN_TB1

Port A=100

Port B=30

After change RET to 50 at all port, SE improved significant and traffic volume also increased. Tilt=50 is calculated and predicted just using Gnet tilt.

-SE improved after Coverage Optimization by reduce overshooting

Previous tilt of site E_FITB_BDG_BM2 is 40,then we check TA and calculated using Gnet tilt this cells has overshooting. After change tilt to proper value=90, SE and CQI improved 64%.

Hope this post will helpful for you to improve SE(Spectrum efficiency) in your network and great optimization jobs.
