BEAM TRAINING OF A RECEIVER DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240250738 titled 'BEAM TRAINING OF A RECEIVER DEVICE

The abstract describes a method for beam training of a receiver device for beamforming reception from a transmitter, utilizing a plurality of multi-arm reception beams.

• Signal strength measurements are performed for each multi-arm reception beam.
• One of the multi-arm reception beams is selected based on the signal strength measurements.
• One arm is nulled for the selected multi-arm reception beam.
• Signal strength measurements are updated by performing measurements with the arm nulled.
• The process is iteratively repeated to obtain further signal strength measurements for multi-arm reception beams with additional arms nulled.
• Reception beams are selected based on signal strength measurements before and after updates.

Potential Applications: - Wireless communication systems - Radar systems - Satellite communication systems

Problems Solved: - Efficient beam training for beamforming reception - Improved signal strength measurements

Original Abstract Submitted

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.
