when the MS is near the BTS, the MS power will be 5dBm. Not 33dBm.
Except at call setup, for few seconds, during which the power control is inhibited. Then, the power control kicks in and the MS power decreases as much as possible.
The MS class 4 can NEVER exceed 33dBm. Why did you say “if the MS transmits more than 33dBm…” ???
Now if you have a MS class “x” that transmits 39dBm, the BTS will still be able to decode the signal. There is not unreliability signal. This does not exist.
Either you did not understand the question, or your senior doesn’t know what he’s talking about. Get another senior…
