ADAPTIVE BEAMFORMING FROM A CONFIGURED BEAM SUBSET - A simplified explanation of the abstract
This abstract first appeared for US patent application 17529141 titled 'ADAPTIVE BEAMFORMING FROM A CONFIGURED BEAM SUBSET
Simplified Explanation
The present disclosure describes a system and method for configuring a beamforming vector using an estimated covariance matrix, which can reduce latency during a beam training procedure.
- The system receives information indicating a subset of TX beams that have been configured on another apparatus.
- The other apparatus transmits pilot signals using the configured subset of TX beams.
- The system transmits an accumulated signal strength value to the other apparatus, which is calculated based on a set of signal strength values measured using received pilot signals.
- The system estimates a channel covariance matrix using the accumulated signal strength value.
- The system calculates a beamforming vector from the channel covariance matrix.
- The system and the other apparatus perform a beam training procedure using their respective beamforming vectors.
Potential Applications
- Wireless communication systems
- Beamforming technology in 5G networks
- Antenna arrays in radar systems
Problems Solved
- Reducing latency during beam training procedures
- Improving the efficiency and accuracy of beamforming in wireless communication systems
Benefits
- Reduced latency in beam training procedures
- Improved performance and reliability of wireless communication systems
- Enhanced beamforming capabilities in 5G networks and radar systems
Original Abstract Submitted
The present disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, directed to configuration of a beamforming vector using an estimated covariance matrix, which may reduce latency commensurate with a beam training procedure. In some aspects, an apparatus may receive, from another apparatus, information indicating a configured subset of a set of TX beams at the other apparatus. The other apparatus may transmit pilot signals via the configured subset of the set of TX beams. The apparatus may transmit, to the other apparatus, an accumulated signal strength value associated with a set of signal strength values measured using received pilot signals. The apparatus may estimate a channel covariance matrix using the accumulated signal strength value, and may calculate a beamforming vector from the channel covariance matrix. The apparatus and the other apparatus may perform a beam training procedure using respective beamforming vectors.
