Power control

Main Aim of the power control is to control interference in the system. it also maximises Capacity in the system.
1.Open loop
2.Inner loop
3. Outer Loop

Open loop: We will control starting power in this PC. So that we can maintain interference & power in the system

Inner Loop: It is also called Fast PC. It takes place at the rate of 1500 . in this PC we ill maintain SIR by controlling Power and interference in the system.

Outer Loop: This is used in connected mode . We can control the quality of the system by maintaining BLER in the System. We also revise the  SIR target in inner loop PC to minimise BLER for a particular service.

Optimization Case Studies:

maxDlPowerCapability >= maximumTransmissionPower

maxDlPowerCapability =  maxTotalOutputPower – dlAttenuation
