Uplink RSSI increased after feature activation

Team

We have done activation of below feature for 100 sites- Cluster but Uplink interference degraded soon after activation

Please assist what is possible reason for this degradation as we expected to improve URSSI


1. FAJ1211714 - Interference Suppression--active for Few sites- having 2msTTi
3. FAJ1212370 - Interference Suppression for all Bearers
4. FAJ1212444 - Uplink Fast Congestion Control
5. FAJ1211584 - UL Efficiency - DCH/EUL Load Balancing
6. FAJ1211376 - Enhanced EUL Cell Edge Coverage
7. FAJ1211334 - Improved CE ladder for E-DCH
8. FAJ1212598 - CE Extension for EUL
11. FAJ1211481 - F-DPCH
12. FAJ1211320 - SRB on HSDPA

Hi mate,

With UL FCC, you will introduce this thresholds:

• fccRotThresholdLow = eulMaxRotCoverage + fccRotMarginLow
• fccRotThresholdHigh = eulMaxRotCoverage + fccRotMarginHigh

You should check how these parameters are configured:

• eulMaxRotCoverage (high capacity suggestion 10 dB)
• eulMaxOwnUuLoad (high capacity suggestion 10 dB)
• fccRotMarginLow (high capacity suggestion 2.5 dB)
• fccRotMarginHigh (high capacity suggestion 4 dB)

Can you share those?

Regards,

The value of the said parameter are the same as per your suggestion

Can you please let me know how to deactivate Enhanced EUL Cell Edge Coverage feature- we have just restarted RBS after loading the license and we suspect the degradation in URSSI is due to this feature
