Establishment of a forward link traffic channel between one or more candidate base stations (104-1 to 104-N) and a mobile station (102) considers forward link quality such that the initial transmit power is set to a level that achieves a desired received signal quality at the mobile station. With this approach, the initial transmit power is set to a mobile-specific power level rather than to a default initial transmit power level. That is, the open loop transmit power control that sets traffic channel power at the outset of a call, or under certain handoff scenarios, uses knowledge of forward link channel loss and interference to set initial transmit power for the traffic channel to the level needed to achieve the target signal quality at the mobile station. Such knowledge is gained from receiving pilot signal measurements for the candidate base stations from the mobile station, which measurements may be improved in accuracy by compensating them for base station loading.
