Hello all.
How to improve Low RS SINR?
Adjust the electrical and mechanical tilt to improve the coverage and focus the signal towards the desired area.
Check interference.
For me, it is best to see the entire spectrum and not the cell average.
Tilts are adjusted and coverage is optimal.
However still low RS SINR (it’s between average and bad depends on sector).
SINR is generally CRS SINR and PDSCH SINR.
We normally increase PDSCH power.
Check the RRU power and play with PA PB parameters.
It should improve.
Also check if features ICIC and UL coordinated multipoint are active.
FSS feature as well.
Hello, Instead of activation of Feature, you have check basic reasons of Low RS SINR causes are:
PCI Planning : SSS reporting RSRP/SINR (2)
You can check Interference.
How about the RSRP is also Low?
Also check Overshooting Cells, you can downtilt as well.
