1. A method in a base station, comprising:
detecting a faulty antenna element in an antenna array, the antenna array transmitting a first beam covering a predetermined range of directions;
determining a target direction in which radiation power dropped due to a fault of the detected faulty antenna element; and
generating a second beam pointing to the determined target direction to combine the first and second beams at the receiver.
