Patent ID: 7532865

Claim:
Outer loop power control method for wireless communications systems, based on CDMA technology, the method comprising: estimating a desired signal to interference ratio received (SIR rec ) based on a data signal ( 107 , 108 ) received from a base station ( 102 , 103 ) or mobile station ( 104 ), setting a desired signal to interference ratio target (SlR target ) that is close to a signal to interference ratio required (SIR rec ) during the normal mode of the outer loop, detecting a start ( 402 ) of the outer loop wind-up, setting a specific desired signal to interference ratio target (SlR target ) during the outer loop wind-up, and detecting a start ( 403 ) of the outer loop unwinding, wherein the desired signal to interference ratio target (SlR target ) is modified at the start ( 403 ) of the outer loop unwinding, to match it to the outer loop power control in normal mode just prior to the start of the outer loop wind up.
