Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing D2D communication systems lack effective solutions for improving the efficiency of sidelink resource selection and reselection in processes, leading to potential resource conflicts and interference among terminal devices.
Innovation Solution
A resource selection method where a first terminal device selects sidelink transmission resources based on a shared resource set, utilizing channel detection results and indication signaling from other terminal devices to optimize resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If terminal devices autonomously select sidelink resources without coordination, then device complexity is reduced, but resource conflicts and interference increase
Solution Approach 1:
The patent implements a feedback mechanism where terminal devices send indication signaling to the network device about their resource selection status. The network device provides feedback information to coordinate resource selection among multiple terminal devices, reducing conflicts while maintaining autonomous selection benefits. This feedback loop enables centralized coordination without significantly increasing device complexity.
2Reliability
If terminal devices perform comprehensive channel detection, then resource selection reliability improves, but detection time and complexity increase
Solution Approach 1:
The patent applies preliminary action by having terminal devices perform channel detection and resource selection in advance before actual data transmission. The network device collects indication signaling from multiple terminal devices and provides coordination feedback beforehand, allowing terminal devices to finalize their resource selections without time-consuming comprehensive detection at transmission moment, thus reducing selection time while maintaining reliability.
3Ease of operation
If multiple terminal devices select resources independently, then device operation simplicity is maintained, but resource conflicts increase
Solution Approach 1:
The patent introduces the network device as an intermediary that coordinates resource selection among terminal devices. Terminal devices send indication signaling to the network device, which processes this information and provides coordination feedback. This intermediary approach maintains the simplicity of autonomous device operation while effectively reducing resource conflicts and interference through centralized coordination.
