Method for operating a base station comprising a plurality of antennas in a wireless radio network

A method for operating a base station in a wireless radio network, the base station comprising a plurality of antennas for transmitting radio frequency signals between the base station and a user equipment, the method comprising:

• receiving, at the base station, at each antenna of a subset of the plurality of antennas a training signal sent from the user equipment;
• determining for each antenna of the subset a corresponding configuration parameter based on the training signal received at the corresponding antenna;
• transmitting a plurality of payload information blocks between the base station and the user equipment using the determined configuration parameters for the antennas and a predetermined transmission scheme;
• receiving a transmission quality parameter based on at least one payload information block of the plurality of payload information blocks;
• and
• determining an adapted transmission scheme based on the received transmission quality parameter.
