Claim:
1. A radio system for relaying radio signals in a cell of a mobile network, the radio system comprising: a base band unit for generating a plurality of grouped cellular radio signals from a cellular radio payload signal; a beam forming unit for providing a beam shape based on a plurality of beam forming vectors for yielding a beam shape characterized by a specific shape, an azimuth angle and an inclination angle identifying a direction of the beam shape; an active antenna system comprising a plurality of antenna elements for relaying the plurality of the grouped payload cellular radio signals according to one of the plurality of beam forming vectors associated with the grouped cellular radio payload signals; a transmit combining unit for combining individual ones of the plurality of the grouped cellular radio payload signals; and a trigger unit for providing a trigger signal to the transmit combining unit, the trigger signal comprising an indication of which one of the plurality of beam forming vectors is used, wherein the trigger unit and the trigger signal are used for a change of the combining in the transmit combining unit and a time slot corresponding to a transmission time interval as present within a communication protocol used for the trigger signal, wherein the grouped payload cellular radio signals are grouped according to a network-determined service criterion, wherein the associated beam forming vector comprises factors for at least one of the antenna elements; and wherein the factors are independently selectable.
