Abstract:
1. An integrated circuit (IC) incorporated in a wireless transmit/receive unit (WTRU) configured to converge target metrics from an initial target metric to a desired target metric that results in a desired transmission power control setting used by a base station, the IC comprising: a receiver configured to receive a series of temporary dedicated channel (DCH) allocations of data signals spaced apart in transmission time intervals on a forward channel; and a processor configured to compute target metrics for implementing forward channel transmission power adjustments in the base station, the processor further configured to perform an error check per each transmission time interval, whereby fixed step size adjustments are made to the target metric with a frequency equal to one adjustment per each transmission time interval in a step down increment for every error check detecting no errors and in a step up increment for every error check detecting an error, such that the step down increments are in response to a detection of a particular number of error conditions in the data signals received on the forward channel at the WTRU, and whereby the target metric adjustment is based on the number of transport blocks of data sent per transmission time interval, the processor further configured to perform an upper and lower bound test for setting the initial target metric, where the upper bound is a first predetermined value added to the initial value and the lower bound is a second predetermined value subtracted from the initial value.
