CHANNEL STATE INFORMATION (CSI) OMMISSION IN ADVANCED MULTIPLE INPUT MULTIPLE OUTPUT (MIMO) CSI FEEDBACK - A simplified explanation of the abstract

This abstract first appeared for US patent application 17778127 titled 'CHANNEL STATE INFORMATION (CSI) OMMISSION IN ADVANCED MULTIPLE INPUT MULTIPLE OUTPUT (MIMO) CSI FEEDBACK

Simplified Explanation

The patent application describes techniques for managing uplink control information (UCI) transmission for a channel state information (CSI) report resulting from measurements of CSI measurement resources. In cases where the CSI report exceeds the allocated uplink resources for UCI transmission, a compressed CSI report can be generated by omitting parameters of the CSI report based on components of the MIMO codebook configuration in the frequency domain (FD) and time domain (TD). The UCI transmission is then generated with the compressed CSI report.

• Uplink control information (UCI) transmission management for CSI reports
• Generation of compressed CSI reports by omitting parameters based on MIMO codebook configuration components

Original Abstract Submitted

Techniques, described herein, include solutions for managing uplink control information (UCI) transmission for a channel state information (CSI) report resulting from measurements of CSI measurement resources. In response to the CSI report exceeding allocated uplink resources of a UCI transmission, a compressed CSI report can be generated by performing an uplink control information (UCI) omission to omit parameters of the CSI report based on components comprising frequency domain (FD) components and time domain (TD) components of the MIMO codebook configuration. The UCI transmission can be generated with the compressed CSI report.
