Sidelink Resource Signaling With Group Header Conflict Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In sidelink communication, resource conflicts often occur due to autonomous resource allocation by terminal devices without central control, leading to inefficiencies and reduced communication performance in group settings.
Innovation Solution
A method where a group member reports channel state information to a group header, which determines optimal resources for sidelink communication, reducing the likelihood of resource conflicts and improving overall group communication performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If resource allocation is based on autonomous selection by terminal devices, then device independence and flexibility are improved, but resource conflicts increase due to lack of central control
Solution Approach 1:
The patent introduces a group header as an intermediary between base station and group members. The group header receives resource allocation information from the base station and distributes it to group members, enabling centralized control within the group while maintaining autonomous operation capabilities. This mediator structure resolves the contradiction by providing coordination without requiring direct base station control for each device.
Solution Approach 2:
The patent segments the resource allocation function into two parts: group-level resource selection by the group header and individual device selection within allocated resources. This segmentation allows devices to maintain autonomous selection capabilities while the group header ensures overall resource coordination, reducing conflicts through hierarchical management.
2Reliability
If centralized resource allocation via base station is implemented, then resource conflict probability is reduced, but system complexity and signaling overhead increase
Solution Approach 1:
The patent divides the centralized control function into hierarchical levels: base station controls group headers, and group headers control group members. This segmentation reduces signaling overhead by eliminating direct communication between base station and each member, while maintaining centralized coordination benefits through the group header intermediate layer.
Solution Approach 2:
The group header acts as an intermediary that simplifies the centralized control architecture. Instead of direct base station-to-member communication, the group header receives and distributes resource allocation information, reducing system complexity and signaling overhead while maintaining effective resource coordination.
3Productivity
If group-based resource management is implemented, then communication efficiency is improved, but resource allocation flexibility for individual devices is reduced
Solution Approach 1:
The patent segments resource allocation into group-level and device-level decisions. The group header manages group-level resource allocation to improve communication efficiency, while individual devices retain freedom to select specific resources within their allocated sets, maintaining adaptability and versatility at the device level.
