Abstract:
In a diversity handover of a communication involving the mobile station, a method for controlling a transmit power from a first base station and from a second base station to the mobile station, a method comprising:determining respective transmit power levels of the first and second base stations; determining a reference power level based on one or more of the determined transmit power levels; determining which of the first and second base stations is a dominant base station and which is a non-dominant base station for the diversity handover communication; determining an average base station transmit power of the dominant base station; using the average base station transmit power of the dominant base station as the reference power level for the dominant base station for the diversity handover communication; adjusting the base station reference power level of the dominant base station to determine an adjusted base station reference power level for the non-dominant base station; and using the base station transmit reference power level to regulate an adjustment to the respective transmit power levels of the first and second base stations for the diversity handover communication.
