Sidelink Platooning Group Merge Control for Easy Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in efficiently separating an existing platooning group from another platooning group in wireless communication systems, particularly after merging operations.
Innovation Solution
A method and apparatus for controlling platooning in a wireless communication system supporting sidelink, where a device receives information on another platooning group, transmits a merge request message, and updates platooning information to maintain and separate platooning information as sub-group information through a platooning level.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If platooning groups merge with each other to increase group size and improve communication efficiency, then the quantity of substance (group members) increases, but the difficulty of separating existing groups later increases
Solution Approach 1:
The patent segments platooning information into hierarchical levels (platoon level and sub-group level). When groups merge, the original group information is preserved as sub-group information under the merged group, maintaining a tree-like hierarchical structure. This segmentation allows easy separation by simply removing sub-group relationships without complex operations, thus resolving the contradiction between increasing group size and maintaining separation ease.
2Device complexity
If platooning information is completely updated after merging, then the information structure is simplified, but historical platooning information is lost
Solution Approach 1:
The patent implements a nested information structure where sub-group information is contained within the parent platoon information. The platooning information includes both the merged group data and nested sub-group data structures. This nesting allows the system to maintain simplified current group information while preserving historical group information in a hierarchical manner, eliminating the need to choose between simplification and information retention.
3Measurement precision
If detailed platooning information is maintained for all merged groups, then measurement precision of group history is improved, but the quantity of information increases
Solution Approach 1:
The patent segments information storage by hierarchy level, storing only essential details at the platoon level and summarized information at the sub-group level. This segmentation reduces redundant information storage while maintaining precise tracking of group history through the hierarchical structure, thus resolving the contradiction between information precision and information volume.

AI summary
Various embodiments provide a method for controlling platooning of a first platooning group by a first device in a wireless communication system, and an apparatus therefor. The method comprises the steps of: receiving, from a second device, information on a second platooning group controlled by the second device; on the basis of the information on the second platooning group, transmitting a merging request message for merging with the second platooning group; and on the basis of merging of a first platooning group with the second platooning group, updating platooning information related to platooning, wherein the platooning information is updated to include first platooning information relating to the existing first platooning group, which corresponds to sub-group information, and second platooning information relating to the merged first platooning group and the second platooning group.
