Title:
METHOD FOR OPERATING A BASE STATION IN A WIRELESS RADIO NETWORK AND CORRESPONDING BASE STATION
Document Type and Number:
WIPO Patent Application WO/2015/114413
Kind Code:
A1
Abstract:
Method for operating a base station in a wireless radio network and base station 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) training signals sent by the user equipment (16) and determines an antenna configuration parameter for each antenna (12) of the subset of the plurality of antennas (12) based on a combination (60-62) of the training signals received in a plurality of different frames (20) at the corresponding antenna (12) for a subsequent transmission of payload information (22, 23) between the base station (11) and the user equipment (16). The combination of the training signals of the different frames may include an averaging and/or a weighting of the training signals.
