Hi Experts,
Please suggest the parameters to improve SINR in LTE(Huawei Vendor).
Thanks
Prakash
Zero, for reducing coverage area go for -177, -300, for gaining 173, 300. Ignore lesser or more than ±300, values can go upto ±600

Hello Experts.
According to your optimization experience, which are necessary actions to increase SINR values on this red area?
Looks like high interference as RSRQ is low even in fair RSRP.
Cell orientation, tilt may be checked.
, too many work to reduce overshooting.
Yeah! That’s my opinion too. 
Without such a No dominant serving cell areas, any parameter action will only hide the problem.
So for these kind problematic area you need to make dominant area by checking whichs cells must serve the area and you must prevent the all other cells which serving from the not planned to the that area as a serving cells.
So one by one check these action
- Uptilt for main planned serving cell
- Downtil for overshooter cells / if you cannot give more tilt , change the decrease CRSGain ( Ericsson ) or pA/pB/Referencesignalpwer ( Huawei )
Totally agree!
The most important objective is to guarantee a strong best server.
And only after that to proceed with parameter adjustments.

You need improve more than 8 dB of difference for one server.
- Antenna Placement and Configuration:
- Ensure proper antenna placement to maximize signal coverage.
- Optimize the antenna tilt and orientation to reduce interference and enhance signal strength.
- Site Planning and Cell Configuration:
- Perform a thorough site survey to identify and address potential sources of interference.
- Optimize cell configuration and frequency planning to minimize interference between cells.
- Power Control:
- Implement power control mechanisms to adjust the transmission power based on the signal quality at the receiver.
- Ensure that the transmitted power is sufficient for good coverage but not excessive, which can cause interference.
- Frequency Band Planning:
- Use efficient frequency band planning to minimize interference between adjacent cells.
- Employ techniques such as frequency reuse to maximize spectral efficiency.
- Interference Management:
- Identify and mitigate sources of interference, such as adjacent cells or other electronic devices.
- Implement interference cancellation techniques or adaptive interference management algorithms.
- MIMO (Multiple Input Multiple Output):
- Use MIMO technology to improve signal quality and capacity.
- Implement advanced antenna systems, such as beamforming, to focus signals in desired directions and reduce interference.
- Handover Optimization:
- Optimize handover parameters to ensure seamless transitions between cells.
- Minimize unnecessary handovers to prevent interruptions and reduce interference.
- Quality of Service (QoS) Management:
- Prioritize traffic based on QoS parameters to ensure that critical data receives better treatment and is less susceptible to interference.
- Network Load Balancing:
- Implement mechanisms to balance the load across cells to prevent congestion and improve SINR in overloaded cells.
- Advanced Receiver Techniques:
- Use advanced receiver techniques, such as interference cancellation and equalization, to improve the SINR at the receiver.
- Dynamic Spectrum Management:
- Implement dynamic spectrum management techniques to adapt to changing radio conditions and optimize resource allocation.
- Network Optimization Tools:
- Utilize network optimization tools and software to continuously monitor and analyze network performance, identifying areas for improvement.
Remember that SINR is a dynamic parameter, and optimizing it requires ongoing monitoring and adjustments to network parameters. Regular network optimization and performance tuning are crucial for maintaining a high-quality LTE network.
