Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently processing channel state information (CSI) due to the lack of effective methods for handling multiple configured codebooks, which are essential for optimizing antenna configurations and improving communication quality.
Innovation Solution
The method involves receiving a configuration of multiple codebooks, each associated with a corresponding antenna port configuration, and computing CSI processing parameters based on this configuration to enhance CSI reporting and processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple codebooks are configured for CSI reporting, then antenna configuration accuracy and communication quality are improved, but processing complexity and computational burden increase
Solution Approach 1:
The patent segments the CSI reporting process by associating different codebooks with different antenna port configurations. Instead of processing all antenna ports uniformly, the system divides the codebook set into multiple groups, each corresponding to a specific antenna configuration. This segmentation allows the UE to process CSI reports more efficiently by focusing computational resources on specific codebook groups rather than handling the entire codebook uniformly, thus reducing overall processing complexity while maintaining accuracy.
Solution Approach 2:
The patent introduces parameter changes by dynamically selecting which codebooks to process based on the configured antenna port settings. The system modifies the CSI reporting parameters by adjusting the codebook selection criteria according to the antenna configuration, enabling the UE to adapt its processing behavior. This parameter adjustment allows the system to maintain high measurement precision for specific antenna configurations while reducing complexity by excluding irrelevant codebooks from processing.
2Productivity
If multiple codebooks are processed for CSI reporting, then communication performance is improved, but processing time and resource consumption increase
Solution Approach 1:
The patent applies partial action by processing only the necessary codebooks relevant to the current antenna port configuration rather than exhaustively processing all possible codebooks. The system identifies and processes only the subset of codebooks that correspond to the configured antenna ports, avoiding unnecessary computational operations. This partial processing approach maintains communication performance by focusing on relevant CSI information while significantly reducing processing time and resource consumption compared to full codebook processing.
Solution Approach 2:
The patent implements preliminary action by pre-configuring the UE with information about which codebooks correspond to which antenna port configurations. This preliminary setup allows the UE to quickly identify and process only the relevant codebooks without needing to perform exhaustive searches or evaluations during the actual CSI reporting process. The pre-established mapping between codebooks and antenna configurations enables rapid, targeted processing that improves communication performance while minimizing processing time.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, a configuration of a channel state information (CSI) report including multiple codebooks, wherein each codebook, of the multiple codebooks, is associated with a corresponding antenna port configuration. The UE may compute at least one CSI processing parameter based at least in part on the configuration of the CSI report. Numerous other aspects are described.
