Patent ID: 8606313

Claim:
A process for performing an Outer Loop power control in an User Equipment for a UMTS telecommunication system comprising a first process of: applying a first estimation of the Signal to Interference (SIR) target (SIR targ ) in accordance with a value of a Block Error Rate (BLER) target received from a base station comprising: receiving the BLER target (BLER targ ) from the base station; performing an estimation of the BLER value (BLER est ) on a number of N1 blocks; comparing the BLER est to the value of the BLER targ and in response to the comparison, increasing said SIR targ when BLER est >BLER targ and decreasing the SIR targ when BLER est <BLER targ ; and a second process in parallel with the first process, the second process comprising: correcting the value of the SIR targ issued by the first process, comprising of the steps of: computing an estimation of the SIR value; counting a number of CRC errors occurring during a predefined sliding window; detecting a double condition comprising: detecting a burst of CRC errors occurring during the predefined sliding window; monitoring for a pre-convergence of the first estimation of the SIR targ , said pre-convergence being when estimation of the SIR value is substantially close to the SIR targ value issued by said first estimation of the SIR targ ; and applying an immediate correction to said SIR targ .
