Try to troubleshoot the root cause of EcNo degradation.. Check below the major reasons and there rectification methodologies
1) Pilot Pollution: Analyse the Scan Mode DT in areas where EcNo is degraded.. If you find more than 4 to 5 or above SCs serving with in 5 to 10 dbm of ur best cell (and best cell is above -80 to -85 dbm) than go for tilt adjustments or Pilot power optimization.
2) Coverage Issue: If best cell is below -85 or -90 depending upon clutter type than try to increase coverage of logical server.
3) If RSCP is good and no pilot pollution: than try to reduce Max power of cells that doesn't have power rejections . this will improve the denominator of the EcNo formula i.e 10log(pilot/channel)
4)If none of the above condition is met than re-drive the areas in offload and loaded hours and check the difference, if offload hours EcNo is good than its purely Loading Impact and go for load sharing b/w freq(if more than 1 freq available)
