1. A method for adjusting alignment for microwave transmissions from a microwave transmitter to a microwave receiver based on a reinforcement learning (RL) model, the method being performed in an alignment adjuster and comprising the steps of:
obtaining state space comprising external state space and internal state space, the external state space comprising at least one value of a parameter related to environmental conditions at the microwave transmitter or microwave receiver, and the internal state space comprising at least one value of a parameter related to alignment of the microwave transmitter;
determining, based on the RL model and the state space, an action in an action space, the action space comprising actions to adjust alignment of the microwave transmitter;
obtaining a measurement of path loss for a transmission from the microwave transmitter to the microwave receiver;
determining a reward value based on the path loss, wherein an increase in path loss results in a reduced reward value; and
adjusting the RL model based on the obtained state space, the determined action and the determined reward value.
