Concurrent Channel State Information (CSI) Capability Reporting using Multiple Codebooks - A simplified explanation of the abstract

This abstract first appeared for US patent application 18084049 titled 'Concurrent Channel State Information (CSI) Capability Reporting using Multiple Codebooks

Simplified Explanation

Abstract: A user equipment (UE) sends information to a base station about its ability to process channel state information (CSI). This information helps the base station to make appropriate requests for CSI from the UE. The UE can specify different CSI processing capabilities for different scenarios and codebook types. It can also define supported combinations of codebook types for concurrent CSI reporting. The UE can set limits on resources and weighting factors for different codebook types. It can restrict the rank information it provides and prioritize CSI report data based on payload size restrictions. The base station or the UE can optimize the utilization of shared CSI resources and relax the minimum time requirements for CSI reporting.

• UE transmits information about its CSI processing capabilities to a base station
• Different CSI processing capabilities can be specified for different scenarios and codebook types
• Supported combinations of codebook types for concurrent CSI reporting can be defined
• Limits on resources and weighting factors for different codebook types can be set
• Rank information provided by the UE can be restricted
• Priority rule can be used to drop CSI report data based on payload size restrictions
• Base station or UE can optimize the utilization of shared CSI resources
• Minimum time requirements for CSI reporting can be relaxed

Potential Applications:

• Wireless communication systems
• 5G and beyond networks
• Mobile devices and base stations

Problems Solved:

• Efficient utilization of CSI resources
• Flexibility in specifying CSI processing capabilities
• Optimization of concurrent CSI reporting
• Handling payload size restrictions

Benefits:

• Improved performance and efficiency of wireless communication systems
• Enhanced flexibility in managing CSI requests and processing capabilities
• Optimal utilization of shared CSI resources
• More efficient reporting of channel state information

Original Abstract Submitted

A user equipment (UE) transmits concurrent channel state information (CSI) processing capability information to a base station. The capability information can take various forms, and is intended to constrain the base station in the types of CSI requests that can be made to the UE. For example, the UE may indicate different CSI processing capabilities for intra-CC and inter-CC cases and/or for different codebook types. The UE may also specify supported combinations of codebook types for concurrent CSI reporting. The UE may also specify maximum resources or weighting factors for different codebook types. The UE may further restrict the rank information it provides and use a priority rule for “dropping” CSI report data due to payload size restrictions. The base station may direct, or the UE may implement, improved utilization of CSI resources that are shared for multiple concurrent CSI reports. Minimum time requirements for CSI reporting may also be relaxed.
