Transmit power planning in the W-CDMA downlink, especially planning of the total transmit power of base stations and their apportionment to common control channels, is discussed taking cell coverage planning into account. A transmit power planning procedure is proposed for common control channels based on both link-level and system-level simulations. An analysis on optimum power allocation for common pilot channels is also presented. Link budgets that are applicable to downlink common control channels are developed and presented.
