Abstract:
A method for adjusting power in a base station, comprising the steps of:receiving a power instruction from a mobile station that is engaged in a macro-diversity communication with the base station; ascertaining a current power of the base station; determining a power adjustment amount responsive to the power instruction from the mobile station that is engaged in the macro-diversity communication with the base station and the current power of the base station; and adjusting the current power of the base station based on the power adjustment amount, wherein said step of determining a power adjustment amount responsive to the power instruction and the current power of the base station comprises the steps of: comparing the current power of the base station to a predetermined threshold; and setting the power adjustment amount equal to a first amount that is less than a first nominal amount if the power instruction corresponds to an increase command and the current power of the base station is greater than the predetermined threshold; setting the power adjustment amount equal to a second amount that is greater than a second nominal amount if the power instruction corresponds to an increase command and the current power of the base station is not greater than the predetermined threshold; setting the power adjustment amount equal to a third amount that is less than a third nominal amount if the power instruction corresponds to a decrease command and the current power of the base station is less than the predetermined threshold; or setting the power adjustment amount equal to a fourth amount that is greater than a fourth nominal amount if the power instruction corresponds to a decrease command and the current power of the base station is not less than the predetermined threshold.
