The present disclosure describes techniques for scaling the precoder output in an antenna system implementing joint transmission to control the total power emitted by a plurality of antennas distributed among multiple antennas. The scaling factor used for scaling the transmit power at each antenna comprises a parameter, NAP, indicating a number of APs in the antenna system. In introduction of the parameter, NAP, enables the scaling factor to be designed such that the total sum power does not increase when additional APs are added to the antenna system.
