Bias error compensated initial transmission power control for data services

A receiving wireless transmit receive unit (WTRU) for implementing transmission power control for a transmitting WTRU that transmits successive data sets in a forward channel where the transmitting WTRU is configured to make forward channel power adjustments as a function of characteristics of the data sets as received over the forward channel, the receiving WTRU comprising:

• a receiver configured to sequentially receive successive data sets transmitted from the transmitting WTRU on the forward channel;
• a processor configured to successively compute transmit power control signals for the transmitting WTRU's forward channel power adjustments based on the characteristics of each of the data sets received on the forward channel;
• said processor configured to successively compute a bias error value based on the cumulative characteristics of the data set signals received on the forward channel;
• and
• a transmitter configured to transmit on a reverse channel the transmit power control signals for the transmitting WTRU's forward channel power adjustments and the bias error values to the transmitting WTRU to thereby enable the transmitting WTRU, in advance of each successive data set after the transmission of a first data set, to adjust forward channel power as a function of the most recently computed transmit power control signal and most recently computed bias error value.
