NR Sidelink Control Information Bit Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In New Radio (NR) Sidelink communication, there is a lack of specific solutions for transmitting request information and coordination information efficiently, leading to limited resource utilization and increased bit requirements for indicating resource locations.
Innovation Solution
The method involves sending control information that includes request and/or coordination information, utilizing resource selection window indication, start and end time location indications, and resource location indications, determined using reference locations, time unit offsets, and Resource Indication Values (RIV), to optimize bit usage and resource selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional methods are used to transmit request information and coordination information separately, then information completeness is maintained, but the number of bits required for control information increases
Solution Approach 1:
The patent combines request information and coordination information into a single control information message transmitted from one terminal to another. This merging reduces the total number of bits required compared to transmitting separate messages, while maintaining all necessary information for resource selection and coordination in NR Sidelink communication
2Measurement precision
If detailed resource location indication is provided, then resource selection precision is improved, but the number of bits required for indication increases
Solution Approach 1:
The patent introduces a resource selection window as an intermediary concept that defines a time range for potential resource selections. Instead of directly indicating specific resource locations with many bits, the window provides a bounded search space, reducing indication bits while maintaining sufficient precision for resource selection through additional compact indicators within the window
3Adaptability or versatility
If flexible resource selection is enabled, then resource utilization is improved, but control information complexity increases
Solution Approach 1:
The patent enables dynamic resource selection by allowing the resource selection window size and position to be adjusted based on communication conditions. The window can be configured with different time lengths and positions, and resource indicators within the window provide flexible selection capability while maintaining a structured control information format that manages complexity
