METHOD AND ARRANGEMENT FOR CONTROLLING TRANSMITTED POWER IN A MULTI-CARRIER SYSTEM

摘要

The invention relates to a method and an arrangement for controlling the total transmitted power in a mobile telephony system with a multiplicity of carrier waves, a multi-carrier system, in which system each carrier wave included has a defined output power at certain known points in time. The invention is characterized in that it comprises measuring the mean power (Pm) of the combined transmitted signal of the carrier waves in the system at points in time when the respective output power of the carrier waves is defined, calculating the desired mean power of the combined transmitted signal of the carrier waves in the system, and controlling the power of the combined transmitted signal to a desired mean power. The method and arrangement according to the invention can also comprise supplying information about the number of carrier waves (N) in the system, which is utilized in calculating the desired mean power of the combined signal of the carrier waves in the system, and supplying information about the desired output power of each single carrier wave in the system, which is utilized in calculating the desired mean power of the combined signal of the carrier waves in the system.
