METHOD AND APPARATUS FOR EXPLICIT CSI REPORTING IN ADVANCED WIRELESS COMMUNICATION SYSTEMS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18046426 titled 'METHOD AND APPARATUS FOR EXPLICIT CSI REPORTING IN ADVANCED WIRELESS COMMUNICATION SYSTEMS
Simplified Explanation
The abstract describes a method for providing channel state information (CSI) feedback in a wireless communication system. The method involves receiving configuration information for the CSI feedback, including a spatial channel information indicator based on a linear combination (LC) codebook. The spatial channel information includes details about the downlink channel matrix, covariance matrix, or eigenvectors. The method further includes deriving the spatial channel information indicator using the LC codebook, which represents a weighted linear combination of basis vectors or matrices. Finally, the CSI feedback, including the spatial channel information indicator, is transmitted over an uplink channel.
