METHOD AND APPARATUS FOR CSI CODEBOOK PARAMETERS - A simplified explanation of the abstract

  • This abstract for appeared for US patent application number 18298901 Titled 'METHOD AND APPARATUS FOR CSI CODEBOOK PARAMETERS'

Simplified Explanation

The abstract describes apparatuses and methods for channel state information (CSI) codebook parameters. It explains that a user equipment (UE) receives information about a CSI report, which includes details about multiple CSI reference signal (CSI-RS) resources and a codebook. The codebook consists of a spatial-domain (SD) basis component, a frequency-domain (FD) basis component, and a coefficient component. The SD basis component has L basis vectors for each CSI-RS resource, while the FD basis component has M basis vectors. The coefficient component contains coefficients associated with pairs of (SD, FD) basis vectors. The information received also includes codebook parameters. The method involves measuring the N CSI-RS resources based on the information, determining the SD basis component, FD basis component, and coefficient component based on the codebook parameters, and transmitting the CSI report.


Original Abstract Submitted

Apparatuses and methods for channel state information (CSI) codebook parameters. A method performed by a user equipment (UE) includes receiving information about a channel state information (CSI) report, the information indicating N>1 CSI reference signal (CSI-RS) resources and a codebook. The codebook includes a spatial-domain (SD) basis component, a frequency-domain (FD) basis component, and a coefficient component. The SD basis component includes Lbasis vectors for each CSI-RS resource r=1, . . . , N. The FD basis component includes Mbasis vectors. The coefficient component includes coefficients associated with (SD, FD) basis vector pairs. The information includes codebook parameters. The method further includes, based on the information, measuring the N CSI-RS resources; determining, based on the codebook parameters, the SD basis component, the FD basis component, and the coefficient component; and transmitting the CSI report.
