NR Terminal CSI Request Codepoint Mapping for Trigger State Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the new radio (NR) system, determining the correspondence relation between codepoints of the CSI request field in downlink control information (DCI) and triggering states for aperiodic and semi-persistent reporting is a challenge, as existing methods lack a clear mapping scheme to trigger reporting operations effectively.
Innovation Solution
A terminal determines the corresponding triggering state by establishing a correspondence relation between the codepoint of the CSI request field and the position of the triggering state, allowing the network side to trigger reporting operations using DCI, with specific approaches involving state ID fields and implicit positioning within configuration information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a correspondence relation between codepoints of CSI request field and triggering states is established, then reporting operations can be triggered effectively by DCI, but the complexity of determining the mapping scheme increases
Solution Approach 1:
The terminal autonomously determines the correspondence relation between codepoints and triggering states based on pre-configured information and implicit positioning rules. The system enables itself to establish the mapping without requiring explicit external configuration, thereby simplifying the triggering operation while maintaining systematic complexity management
Solution Approach 2:
Configuration information including triggering state lists and codepoint mappings is prepared in advance through implicit positioning. The correspondence relation is established beforehand based on predetermined rules, allowing the terminal to quickly determine the mapping when DCI arrives, thus facilitating efficient reporting trigger operations
2Productivity
If implicit positioning within configuration information is used to determine triggering states, then the mapping scheme becomes more efficient, but the precision of triggering state identification may be reduced
Solution Approach 1:
The terminal uses feedback from the DCI codepoint value to identify the corresponding triggering state through implicit positioning. The system continuously refines the identification process by cross-referencing the codepoint with pre-established correspondence relations, ensuring accurate triggering state determination while maintaining efficient mapping operations
Solution Approach 2:
The patent introduces an additional dimension of implicit positioning based on configuration information structure. Instead of relying solely on explicit state IDs, the system uses the positional relationship within the configuration list as an identifying dimension, thereby improving mapping efficiency while maintaining identification precision through multi-dimensional verification
