Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple CSI-RS resources are configured for channel measurement in mTRP scenarios, then channel measurement capability is improved, but CSI processing resource occupation increases
Solution Approach 1:
The patent segments the determination of occupied CSI processing resources into multiple distinct components: occupied CSI processing units, occupied active CSI resources, and occupied active CSI-RS ports. Each component is calculated separately based on actual CSI measurements, allowing for granular control and optimization of resource allocation in mTRP scenarios
Solution Approach 2:
The patent changes the parameter of resource occupation determination from a fixed or over-estimated value to a dynamic value based on actual CSI measurements. By determining occupied resources based on actual measurement data rather than configuration alone, the system adapts resource allocation to real-time channel conditions, reducing unnecessary resource occupation
2Productivity
If accurate determination of occupied CSI processing resources is implemented, then resource allocation efficiency is improved, but processing complexity increases
Solution Approach 1:
The patent performs preliminary determination of occupied CSI processing resources based on actual CSI measurements before final resource allocation decisions are made. By calculating the occupied resources in advance using measurement data, the system prepares optimization information that guides subsequent resource allocation, reducing overall processing complexity
Solution Approach 2:
The patent implements a feedback mechanism where actual CSI measurements are used to determine occupied processing resources, which then inform resource allocation decisions. This closed-loop approach uses real measurement data to continuously optimize resource allocation efficiency while maintaining manageable processing complexity through systematic feedback utilization

AI summary
Certain aspects of the present disclosure provide techniques for channel state information (CSI) processing occupation determination that can be used even in multiple transmission reception point (mTRP) scenarios. A method that may be performed by a user equipment (UE) includes receiving a channel state information (CSI) reporting configuration configuring the UE with a plurality of CSI reference signal (CSI-RS) resources for channel measurement (CMRs). The method includes determining a number of occupied CSI processing units, a number of occupied active CSI resources, and/or a number of occupied active CSI-RS ports based on an actual number of CSI measurements. The method includes performing CSI measurement based on the determination.
