Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Terminal devices face challenges in efficiently utilizing their processing capability for CSI reports due to insufficient processing capacity for measuring and calculating multiple CSI-RSs, leading to incomplete or delayed CSI feedback.
Innovation Solution
A terminal device is equipped with a communicator and controller to prioritize and manage the processing of CSI measurements, allowing it to selectively update and transmit CSI reports based on available processing units, ensuring efficient use of resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the terminal device measures and calculates multiple CSI-RSs for comprehensive CSI reports, then the measurement precision and reliability of CSI feedback is improved, but the processing capability and time required exceed the terminal device capacity
Solution Approach 1:
The patent segments the CSI measurement process by dividing multiple CSI-RS resources into different groups or sets, where the terminal device can selectively measure and calculate CSI for different segments based on available processing capability. This allows comprehensive CSI feedback to be achieved through multiple smaller measurement tasks rather than one overwhelming task.
Solution Approach 2:
The patent implements partial action by allowing the terminal device to measure and calculate CSI for a subset of CSI-RS resources when processing capability is limited. The device can prioritize certain CSI-RS measurements over others, providing partial CSI feedback that is sufficient for current communication needs without exceeding processing capacity.
2Productivity
If the terminal device processes all CSI measurement items completely, then the productivity and completeness of CSI feedback is improved, but the processing time and resource consumption exceed available capacity
Solution Approach 1:
The patent applies periodic action by enabling the terminal device to perform CSI measurements for different CSI-RS resources at different time instances. Instead of processing all measurements simultaneously, the device can periodically update CSI feedback for different resource sets as processing capability becomes available, ensuring complete feedback over time without time constraints.
Solution Approach 2:
The patent implements preliminary action by having the terminal device prioritize and pre-process certain CSI measurement items that are more critical or have higher priority. The device can prepare CSI feedback for high-priority CSI-RS resources first, ensuring that the most important measurement results are available within tight time constraints while lower-priority measurements can follow.
