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 are 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.
