29.0 How does Power Control affect the Reverse Link Near-Far Problem?
In order to minimize the near-far problem, the goal in CDMA systems is to assure that all mobiles achieve the same received power levels at the Base Station.
The target value for the receive power level shall be the minimum level possible which allows the link to meet user-defined performance objectives (Bit Error Rates, Frame Error Rates, Capacity Estimates, Dropped-call Rate Estimates, and Coverage goals).
In order to implement such a strategy, mobiles that are closer to the Base Station must transmit less power than mobiles that are further away from the Base Station.
