In CDMA cellular systems, site selection diversity transmit (SSDT) power control is employed during soft handover to reduce interference in the downlink. In SSDT, mobile stations select a cell from active cells during soft handover based on the received power of common pilot signals. The selected cells transmit data signals, and the other cells suspend transmission of data signals. We introduce multiple-SSDT as a natural extension of SSDT, and three approaches to enhance the performance of SSDT are presented. With the enhancements, it is possible to eliminate residual frame errors, and to optimize the measurement period of common pilot signals. Also it is possible to reduce interference with efficient transmission of control signals.
