A method for power control of a wireless communication device (2) comprises the steps of defining the transmission power of at least one transmitter (12) of the wireless communication device (2), defining a power index (POW.sub.t) on the basis of the transmission power of the transmitter (12), and selecting at least one limit value. The power index (POW.sub.t) is compared with the limit value and, on the basis of the comparison, it is deduced whether there is a need to adjust the transmission power of the wireless communication device (2). The transmission power may then be adjusted accordingly. A related wireless communication device and a system shown.
