We split a B28 carrier from 20 MHz into 10+10 MHz, and there has been an increase in drop rates. All parameters related to coverage, power, and configuration are properly aligned.
What could be the possible reasons for the increase in PS and CS drop rates?
Is the RS power affected? Is the TX power the same after the split?
Yes, the same power per PRB remains unchanged.
Is there sufficient guard band maintained between the two new carriers?
How much guard band is required?
Could you explain the reason for this split? What was the objective behind it?
The frequency was relocated by the government for all operators.
