1. A network node configured to communicate with a wireless device (WD), the network node comprising a radio interface and processing circuitry, the processing circuitry configured to:
obtain beam forming weights for generating a shaped radiation pattern providing a same effective isotropic power radiated (EIPR) at multiple locations inside a target cell; and
apply the obtained beam forming weights to signals directed to an array of antenna elements of the radio interface to generate the shaped radiation pattern.
