RECEIVING BEAM SELECTION USING HYBRID CHANNEL BASED BEAMFORMING AND CODEBOOK BASED BEAMFORMING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240030997 titled 'RECEIVING BEAM SELECTION USING HYBRID CHANNEL BASED BEAMFORMING AND CODEBOOK BASED BEAMFORMING
Simplified Explanation
The patent application describes apparatuses and methods for selecting a receiving beam based on hybrid channel-based beamforming and codebook-based beamforming. The user equipment (UE) determines if it is in a low signal-to-noise ratio (SNR) state based on a first measurement and predetermined threshold values. If the UE is in a low SNR state, it estimates the channel covariance matrix for channels at a set of antenna elements based on channel-based beamforming. Then, a set of test beams is selected based on the channel covariance matrix, and a set of codebook measurement beams is further selected based on the set of test beams. Finally, a receiving beam is selected based on measurements performed on the set of codebook measurement beams.

Original Abstract Submitted
some aspects relate to apparatuses and methods for selecting a receiving beam based on hybrid channel based beamforming and codebook based beamforming. a user equipment (ue) can determine, based on a first measurement related to signal to noise ratio (snr) and predetermined threshold values, whether the ue is in a low snr state. if the ue is in a low srn state, the ue can derive an estimated channel covariance matrix rfor channels at a set of antenna elements of the ue based on channel based bearmforming (chbf). afterwards, a set of test bears {0, . . . n−1} is selected based on the channel covariance matrix r, and a set of codebook measurement beams is further selected based on the set of test beams. a receiving beam is selected based on a set of measurements performed on the set of codebook measurement beams at the measurement opportunity for codebook based beamforming (cbbf).
