Abstract

In 3GPP W-CDMA, high speed downlink packet access functionality is implemented using the high speed downlink shared channel (HS-DSCH) and its associated control channels. In this paper, we describe the overall structure of HS-DSCH and its control channels: the high speed shaped control channel (HS-SCCH) and the high speed uplink DPCCH (HS-DPCCH). We then present detailed link and system simulation results supporting the control channel design. In addition, a new power control method to support HS-DPCCH operation during soft-handoff is described. The proposed algorithm automatically adjusts the power ratio between the control and data channels based on propagation conditions and outperform the conventional scheme with minimum impact to the DPDCH performance.
