In order to provide a multiple services, especially multimedia and high-bit-rate packet data, Universal Mobile Telecommunication Services adopted Wideband Code Division Multiple Access (WCDMA) act as the mainstream air interface solution for the third-generation networks. An in-depth study of Soft Handoff (SHO) in the downlink direction of WCDMA network is carried out. The link-level study begins with the SHO effects on the downlink interference analysis and power allocation for each downlink-dedicated channel. To the users at the cell boundaries, the inter-cell interference is the main part of the total interference, especially with higher orthogonality. Simulation result shows that SHO decreases the probability of over-power Quality of Service (QoS) deterioration for the users at cell boundaries. However, 2-way SHO has a better performance than hard handoff and 3-way SHO, because it requires less dedicated power to meet the QoS for corner users.
