The present disclosure provides an antenna array () for relaying radio signals into a cell () of a communication network (). The antenna array () comprises a plurality of uplink beam forming vectors () selectable as an uplink beam shape for an uplink relaying and a plurality of downlink beam forming vectors () selectable as a down link beam shape for a down link relaying. The plurality of uplink beam forming vectors () and/or the plurality of the downlink beam forming vectors () may be adjusted at a digital radio interface and forwarded from the digital radio interface to the antenna array (). An individual one () of the plurality of uplink beam forming vectors () and an individual one () of the plurality of downlink beam forming vectors () are independently selectable using a local knowledge () about the cell. The present disclosure further provides a communication network () comprising a plurality of the antenna arrays (---N) for relaying radio signals into the communication network (). The communication network () further comprises a network playing system () adapted to independently select an individual one (---N) of the plurality of uplink beam forming vectors (---N) and an individual one (---N) of the plurality of downlink beam forming vectors (---N) for at least one of the antenna arrays (---N) using a local knowledge () about the communication network (). The present disclosure further provides a method for relaying radio signals into a cell () of the communication network (), a method () for planning the communication network (), and a method () for relaying radio signals into cells (---N) of the communication network (); all methods () using a knowledge () about the communications network ().
