ENHANCED CSI REPORTING FOR MULT-TRP OPERATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17905292 titled 'ENHANCED CSI REPORTING FOR MULT-TRP OPERATION

The patent application discusses enhanced channel state information (CSI) reporting, which involves encoding a CSI reporting configuration for a first and second transmission and reception point (TRP). The CSI reporting configuration includes at least one codebook configuration, which may consist of a rank restriction configuration or a codebook subset restriction (CBSR) configuration. These configurations correspond to specific TRP measurements, TRPs, or channel measurement resources associated with the TRPs. A received CSI measurement communication from a user equipment (UE) is decoded based on the CSI reporting configuration.

• Enhanced channel state information (CSI) reporting with specific configurations for different transmission and reception points.
• Codebook configurations including rank restriction and codebook subset restriction for accurate reporting.
• Correspondence of configurations to TRP measurements, specific TRPs, or channel measurement resources.
• Decoding of CSI measurement communication from UE based on the reporting configuration.

Potential Applications: - Wireless communication systems - 5G networks - Internet of Things (IoT) devices

Problems Solved: - Improved accuracy in CSI reporting - Enhanced communication reliability - Efficient resource allocation in wireless networks

Benefits: - Enhanced network performance - Better quality of service for users - Optimal resource utilization

Commercial Applications: Title: Enhanced CSI Reporting Technology for Next-Generation Wireless Networks This technology can be utilized in telecommunications companies, network equipment manufacturers, and IoT device providers to enhance the efficiency and reliability of wireless communication systems. It can lead to improved network performance, better user experience, and increased competitiveness in the market.

Questions about Enhanced CSI Reporting Technology: 1. How does enhanced CSI reporting benefit wireless communication systems? Enhanced CSI reporting improves the accuracy of channel state information, leading to better resource allocation and network performance.

2. What are the potential applications of enhanced CSI reporting technology beyond wireless networks? Enhanced CSI reporting technology can also be applied in IoT devices, smart city infrastructure, and autonomous vehicles to improve communication reliability and efficiency.

Original Abstract Submitted

Enhanced channel state information (CSI) reporting may include encoding a CSI reporting configuration associated with a first transmission and reception point (TRP) and a second TRP. The CSI reporting configuration may include at least one codebook configuration. The at least one codebook may include at least one of a rank restriction configuration or a codebook subset restriction (CBSR) configuration. The at least one of the rank restriction configuration or the CBSR configuration may correspond to at least one of a particular type of TRP measurement, a particular TRP of the first TRP or the second TRP, or channel measurement resources (CMRs) associated with at least one of the first TRP or the second TRP. A CSI measurement communication received from a user equipment (UE) may be decoded. The CSI measurement communication may be based on the decoded CSI reporting configuration.
