Abstract

The present disclosure relates to a radio system (1), a base band unit (20) and a method (100) for relaying radio signals in a cell (101) of a mobile network. The radio signals are relayed according to a service criterion (300). With the present invention the radio signals are grouped into a grouped payload signal (30-1, 30-2, . . . , 30-M) and a grouped receive signal (220-1, 220-2, . . . , 220-M) according to the service criterion (300). The grouped payload signal (30-1, . . . , 30-M) and the grouped receive signal (220-1, 220-2, . . . , 220-M) are associated with a beam forming vector (40-1, 40-2, . . . , 40-M). The grouping according to the present disclosure helps to improve a quality of service provided to an individual user of the mobile network. The associated beam forming vector (40-1, 40-2, . . . , 40-M) may be provided and adjusted at a digital radio interface DRI (200). Furthermore the present disclosure provides various computer programme product implementing the various aspects.
