Abstract:
A base station (11) for a wireless radio network (10) comprises a plurality of antennas (12) for transmitting radio frequency signals between the base station (11) and a user equipment (16). The base station (11) receives at each antenna (12) of a subset of the plurality of antennas (12) a training signal sent by the user equipment (16) in a first frame (20) and determines an antenna configuration parameter for each antenna (12) of the subset of the plurality of antennas (12) based on the training signal received in the first frame (20) for a subsequent transmission of payload information (33, 34) between the base station (11) and the user equipment (16) in a second frame (30) which is different from the first frame (20).
