B.2 Closed loop control

05.083GPPRadio subsystem link controlTS

A pure closed loop is achieved by setting  = 0. The output power will than be:

P = 0 – CH

In this case, CH is the actual power level (relative to 0 ) commanded by network. It can be based on the received signal level measured at the BTS. Power control commands can be sent when required in order to achieve the target received signal level.
