Patent ID: 8116351

Claim:
A method implemented in a wireless transmit/receive unit (WTRU) for power control of a wireless communication, comprising: receiving data signals from a base station on a dedicated physical channel; receiving data signals from the base station on a common pilot channel; determining a received signal code power change for the data signals received on the dedicated physical channel (ΔDPCH_RSCP) over an observation period; determining a received signal code power change for the data signals received on the common pilot channel (ΔCPICH_RSCP) over an observation period; determining a power differential between the determined power changes ΔDPCH_RSCP and ΔCPICH_RSCP; determining target metrics for power adjustments of the dedicated physical channel based on detection of predetermined error conditions in the signals received on the dedicated physical channel; and transmitting power adjustment signals to the base station based on the determined target metrics and on the determined power differential.
