| 1. Outer loop power control method for wireless communications systems, based on CDMA technology, the method comprising:
estimating a desired signal to interference ratio received (SIRrec) 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 (SlRtarget) that is close to a signal to interference ratio required (SIRrec) 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 (SlRtarget) during the outer loop wind-up, and
detecting a start (403) of the outer loop unwinding,
wherein the desired signal to interference ratio target (SlRtarget) 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.
