High speed dedicated physical control channel power control method and apparatus

The present invention provides a high-speed dedicated physical control channel power control method and apparatus, wherein the method comprises: if the UE is in soft handover, and is configured to transfer multi-stream mode, the UE acquires all the cells of each cell group a first set of corresponding HS-DPCCH and HS-DPCCH power offset adjustment step; for each cell corresponding to the UE group for all cells in the group, the first UE satisfy the preset condition, the UE HS-DPCCH according to the adjustment step a first length, and HS-DPCCH power offset determined power offset of HS-DPCCH second group of cells; the UE adjust transmission power of HS-DPCCH according to the current HS-DPCCH power offset of the second group of cells. A method to solve the above-described HS-DPCCH reception performance of the prior art problems caused by differences in the uplink path losses for each cell.
