Claim 5:
6. The method as claimed in claim 1, wherein the applying of machine learning in the form of reinforcement learning comprises:
obtaining an initial version of the action value function;
obtaining the reward function;
performing iterations of the following at different points in time and thereby at different combinations of state information, action information and reward information:
obtaining state information regarding a current state;
obtaining action information indicative of a precoder being applied by the multi-antenna transmitter during the current state;
obtaining, from the reward function, reward associated with application of the precoder indicated by the obtained action information; and
providing, based on the obtained reward information, the obtained state information and the obtained action information, an updated version of the initial action value function or of a version of the action value function updated in a previous iteration; and

providing the adapted action value function based on the updated version of the action value function resulting from the performed iterations.
