Sidelink Carrier Aggregation Configuration for Wireless Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carrier aggregation solutions in wireless communications are inadequate for sidelink scenarios where network nodes communicate directly without a network control node, leading to instability and inaccurate configuration of secondary carriers due to mobility and lack of network control node participation.
Innovation Solution
An electronic apparatus and method that determines relevant parameters of available component carriers in sidelink scenarios and configures them as secondary carriers for carrier aggregation, enabling autonomous configuration without network control node involvement, thereby stabilizing communication in both in-coverage and out-of-coverage situations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If carrier aggregation is implemented in sidelink scenarios without network control node participation, then communication flexibility and autonomy are improved, but configuration accuracy and stability deteriorate
Solution Approach 1:
The patent enables network nodes to autonomously perform carrier aggregation configuration without network control node participation. The transmitting network node determines available component carriers and configures secondary carriers based on predetermined conditions, allowing the system to serve itself in sidelink scenarios.
Solution Approach 2:
The patent introduces specific parameter determination mechanisms for sidelink carrier aggregation, including determining relevant parameters of available component carriers and comparing them against predetermined conditions. This parameter-based approach enables accurate configuration despite the absence of network control.
2Reliability
If network nodes autonomously configure secondary carriers in sidelink, then communication reliability in out-of-coverage scenarios is improved, but system complexity increases
Solution Approach 1:
The patent establishes predetermined conditions and parameters for carrier aggregation configuration before actual communication occurs. Network nodes prepare by determining available component carriers and their parameters in advance, enabling reliable autonomous operation without real-time network control.
Solution Approach 2:
The patent implements a feedback mechanism where the transmitting network node determines whether relevant parameters of available component carriers meet predetermined conditions. This feedback loop ensures accurate secondary carrier configuration while maintaining manageable system complexity through structured decision-making.
3Area of stationary object
If carrier aggregation uses multiple component carriers in sidelink, then transmission bandwidth is improved, but measurement and detection difficulty increases
Solution Approach 1:
The patent divides the carrier aggregation configuration process into distinct segments: determining available component carriers, evaluating their parameters against predetermined conditions, and selectively configuring secondary carriers. This segmentation makes the measurement and detection process more manageable despite multiple carriers.
