Abstract:
In a receiver of a UMTS telecommunication system a process for performing the Outer Loop power control in a User Equipment is provided. The receiver includes an improved outer loop power control mechanism that estimates a Signal to Interference target (SIRtarg) based on a Block Error Rate target (BLERtarg) received from a base station. The outer loop control mechanism estimates a BLER value (BLERest) based on a number of received blocks and then adjusts a SIR target value (SIRtarg) based on the relationship between BLERtarg and BLERest. Meanwhile, simultaneously in parallel, the outer loop power control mechanism monitors for a potential convergence of a first SIR value with the SIRtarg and upon detection of such potential convergence applying a correction to SIRtarg.
