Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems face inefficiencies due to high control signal overhead during state transitions, especially in scenarios with short communication times or small data transmission, which hinders efficient communication.
Innovation Solution
A wireless communication system where a base station configures and releases communication mode transitions using predetermined control signals, reducing the need for frequent notifications and overhead, by classifying the wireless station as a static device and using preconfigured timing for mode transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If communication mode transitions are performed frequently to enable short communication or small data transmission, then communication flexibility is improved, but control signal overhead increases
Solution Approach 1:
The base station performs preliminary classification of the wireless station as a static device and pre-configures transition timing before actual mode transitions occur. This allows multiple mode transitions to be executed without repeated classification and configuration signaling, reducing control overhead while maintaining communication flexibility for short transmissions.
Solution Approach 2:
The patent creates a universal communication mode configuration that applies to all static wireless stations. By establishing a general classification and transition timing mechanism that can be reused across multiple communications, the system avoids repeated individual configuration signaling, thereby reducing control signal overhead while maintaining adaptability.
2Reliability
If conventional RRC state transitions are used for each communication event, then communication reliability is maintained, but communication efficiency deteriorates due to overhead
Solution Approach 1:
The base station performs preliminary classification of the wireless station as a static device and pre-configures transition timing before actual mode transitions occur. This allows multiple mode transitions to be executed without repeated classification and configuration signaling, reducing control overhead while maintaining communication flexibility for short transmissions.
Solution Approach 2:
The wireless station, once classified as static, automatically follows the pre-configured transition timing for mode changes without requiring continuous base station intervention. This self-service mechanism reduces signaling overhead while maintaining reliable communication through predetermined transition rules.
