ABSTRACT:
Uplink power control is provided to maintain the integrity of the uplink HS-DPCCH when the UE goes into SHO. The target pilot SNR threshold is controlled by considering the pilot signal strength of the serving Node-B and/or the uplink channel condition of the serving Node-B when deciding to increase or decrease the target pilot SNR threshold of Nodes-B.
