Abstract

A method of power control m a wireless communication system, wherein blocks are transmitted from a transmitter to a receiver via a wireless transport channel. The method comprises comparing a target signal quality value with a received signal quality value and providing the results of the comparing step to the transmitter to adjust transmit power based on the comparing step. The target signal quality value is set by the following steps: determining an initial target value; detecting if a data block has been received; detecting if received blocks have been successfully decoded, and identifying the received blocks as pass or fail blocks; and decreasing the target value when pass blocks are received and increasing the target value when failed blocks are received subject to monitoring a period of inactivity on the transport channel in which no blocks, or only failed blocks are received and where the period of inactivity exceeds a threshold reducing a current target value to a value determined by the target value at commencement of the period of inactivity and possibly by the initial target value.
