Abstract
A method and other arrangements are disclosed for beam training of a receiver device configured for beamforming reception from a transmitter. The beam training is based on a plurality of multi-arm reception beams. The method includes performing signal strength measurements for each of the multi-arm reception beams, selecting one of the multi-arm reception beams based on the signal strength measurements, nulling one arm for the multi-arm reception beam, and updating the signal strength measurements by performing signal strength measurements for the multi-arm reception beam with the arm nulled. The method also includes iteratively repeating the selecting, nulling, updating and determining steps so as to obtain further signal strength measurements for multi-arm reception beams with additional arms nulled, selecting a reception beam, based on the signal strength measurements before and after the updates and selecting a reception beam based on the signal strength measurements before and after the updates.
