Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If CSI report configuration includes multiple sub-configurations for different spatial adaptation patterns, then network adaptability and performance are improved, but device complexity and processing overhead increase
Solution Approach 1:
The CSI report configuration is divided into multiple sub-configurations, each corresponding to a specific spatial adaptation pattern. This segmentation allows the network to configure different CSI reporting parameters for different spatial patterns independently, improving adaptability while managing complexity through structured organization of configuration parameters.
Solution Approach 2:
The patent introduces dynamic activation and deactivation mechanisms for CSI reporting sub-configurations through MAC CE signaling. The network can dynamically activate only the necessary sub-configurations based on current spatial adaptation needs, reducing processing overhead and device complexity while maintaining the capability to support multiple spatial patterns when required.
2Loss of energy
If MAC CE includes fields for activating/deactivating multiple sub-configurations, then network energy saving is improved, but signaling complexity increases
Solution Approach 1:
The MAC CE structure is segmented into multiple fields, with each field corresponding to a specific sub-configuration activation/deactivation status. This segmentation allows efficient bit-level control of individual sub-configurations, enabling fine-grained energy management while keeping the signaling structure organized and manageable.
Solution Approach 2:
The patent implements periodic monitoring and evaluation of CSI reporting needs by the network. Based on this periodic assessment, the network activates or deactivates sub-configurations through MAC CE signaling, creating a cyclic process that optimizes energy consumption while managing signaling overhead through time-based control mechanisms.

AI summary
Example embodiments of the present disclosure provide solutions for enhanced channel state information (CSI) activation/deactivation operation. In an example method, a terminal device receives a MAC CE comprising at least one field for a CSI report configuration, wherein the CSI report configuration comprises a plurality of sub-configurations. The terminal device further determines activation or deactivation of at least one of the plurality of sub-configurations at least based on the at least one field in the MAC CE. In this way, the operation of activating/deactivating CSI reporting for one or more sub-configurations is enabled when multiple sub-configurations are included or associated with a same CSI reporting configuration.
