Can any one guide how can we inprove SINR in LTE.?

Hi,
can any one guide how can we inprove SINR in LTE.


#2

Check pci mode first


#3

Then Ho parameters, check area if it has cross sector or feeder, if so the route cause will be due to high traffic, you can know that from prb utilization and user no.


#4

Check interference with other 4G site by pci mode, or interference another system that might use same freq with 4g or check external interference.


#5
  1. Reduce the coverage overlaps.
  2. Optimize PCI for conflict and clashes.
  3. Optimize Neighborhood with logical relations and parameter settings of offsets and hysteresis.
  4. Remove overshooters and swaps.
  5. All connectors should be properly done and tapped.
  6. Analyse PIMs in the area with scanner and escalate to Freq Allocation Authority.
  7. Check the activated features. Some features has impact on SINR. Identify and optimize the parameters.

Which features impact SINR negatively?

Which features impact SINR negatively?

Lovely. It’s not the features which impact SINR badly. It’s their configuration that may result into. Like configuring DRX with elapsed timers etc.

Plus check your vendor feature description. Like in Ericsson, introduction of features cover impact on SINR, thpts, capacity or coverage gain etc.
