METHODS FOR USING TWO-WAY BEAMFORMING OPERATIONS FOR CALIBRATION - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 17661517 Titled 'METHODS FOR USING TWO-WAY BEAMFORMING OPERATIONS FOR CALIBRATION'
Simplified Explanation
This abstract describes a method and device for calibrating two-way beamforming operations. The device receives a set of reference signals from a network node and uses them to estimate a beamformed channel. It then transmits another set of reference signals to the network entity and receives feedback signals containing measurements of the transmitted signals. Using these feedback signals and the estimated beamformed channel, the device calculates calibration adjustment factors for the beam weights. Finally, it performs a calibration adjustment operation based on these factors.
Original Abstract Submitted
Method and apparatus for two-way beamforming operations for calibration. The apparatus receives a first set of reference signals from a network node using N sets of beam weights over N symbols. The apparatus estimates a complex-valued beamformed channel based on the first set of reference signals. The apparatus transmits a second set of reference signals to the network entity using the N sets of beam weights. The apparatus receives a set of feedback signals from the network entity comprising measurements of the transmitted second set of reference signals. The apparatus computes a set of calibration adjustment factors between transmit and receive parts of a set of beam weights based on the set of feedback signals and the estimated complex-valued beamformed channel. The apparatus performs a calibration adjustment operation based on the computed set of calibrated adjustment factors.
