0% Load on Planning Tools

By using Planning Tools U-Net, we can change the Actual Load Based on daily KPI monitoring of RB (DL & UL) usage in order to know SINR level on 4G Live Network .

How to Change 80% Load on Planning Tools

In this slide, We have to change the actual load from 0% to 80% in whole mini cluster that we want to analysis in order to know what is the impact of Load with SINR level.

RSRP Comparison

From Simulation of mini cluster there is no difference between 0% Load compare with

80% Load.

In this simulation one site have configuration of 10 MHz and all cell’s using the same Physical and RF Parameter as field implementation

SINR Comparison

From Simulation of mini cluster there is degradation of SINR > 0 dB at 5.75% due to

Load incremental from 0% to 80%.

It’s mean in every time we want to do optimization, we have to consider load of RB

utilization from OSS Daily Monitoring.

We have to mapping each cell and implement to our planning tools as our reference or

justification if any degradation of SINR KPI during Drive Test as the time goes by.

OSS KPI Analysis

On the week days, DL PRB Utilization

higher than weekend days

User Number almost have correlation

with the increment of DL PRB Usage

MCS QPSK Decrease Significant on

the weekend days according with Low

PRB Usage

MCS 16 QAM Relative Increase on

the weekend days according with Low

PRB Usage

MCS 64 QAM Increase Significant on

the weekend days according with Low

PRB Usage
