D2D Connection Control in V2X 5G NR Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions lack effective control mechanisms for network devices to manage unicast and multicast connections in Vehicle to Everything (V2X) 5G New Radio (NR) systems, particularly in controlling terminal devices and handling UE-UE interactions, granularity of control, and handling abnormal conditions.
Innovation Solution
A method and devices for information processing that enable a first terminal device to report its device-to-device (D2D) connection situation to a network device, and trigger parameter combinations for SL data sending/receiving parameters between terminal devices, allowing network control over unicast or multicast connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If unicast and multicast connections are introduced in V2X 5G NR system, then communication versatility is improved, but control mechanism complexity increases
Solution Approach 1:
The patent segments the control mechanism into two distinct parts: network device control for unicast connections and terminal device control for multicast connections. This segmentation allows each control type to be optimized independently, managing complexity while maintaining versatility
Solution Approach 2:
The patent inverts the traditional control approach by allowing terminal devices to autonomously control multicast connections without network device intervention. This inversion simplifies the overall control mechanism while maintaining communication versatility
2Reliability
If network devices control terminal devices in D2D communication, then connection reliability is improved, but control granularity is reduced
Solution Approach 1:
The patent applies local quality by differentiating control granularity based on connection type: network devices provide fine-grained control for unicast connections while terminal devices handle multicast connections autonomously. This localized approach maintains reliability where needed while preserving operational granularity
3Stability of the object's composition
If timer mechanism is implemented for connection management, then connection stability is improved, but system complexity increases
Solution Approach 1:
The patent implements self-service through autonomous timer mechanisms at terminal devices that automatically manage connection timeouts and state transitions without requiring complex network device intervention. This maintains connection stability while minimizing system complexity

AI summary
A method for information processing includes that: a first terminal device sends information to a second electronic device, and the first terminal device starts a first timer, the first terminal device being a terminal device that performs device-to-device communication. A first terminal device and a second terminal device are also provided.
