Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in initial access configurations for user equipment, as they lack dynamic adaptation based on user equipment position and radio conditions, leading to suboptimal single-phase or multi-phase configurations.
Innovation Solution
An apparatus and method within a base station, utilizing a processor and memory, determine user equipment position and radio conditions to dynamically choose between single-phase and multi-phase configurations based on specific criteria such as distance, signal-to-noise ratio, and modulation complexity, enabling flexible adaptation for efficient initial access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a single-phase configuration is used for initial access, then the access procedure is simplified and faster, but it may not be suitable for all user equipment conditions leading to suboptimal performance
Solution Approach 1:
The base station dynamically determines whether to perform single-phase or multi-phase configuration based on first information about user equipment conditions (position, radio conditions). This dynamic adaptation allows the system to switch between configuration types according to real-time conditions, resolving the contradiction between speed and adaptability.
Solution Approach 2:
The system changes the configuration parameter (single-phase vs. multi-phase) based on determined first information characteristics. By adjusting this parameter according to user equipment position and radio conditions, the system achieves both fast access when appropriate and adaptability when needed.
2Adaptability or versatility
If a multi-phase configuration is used for initial access, then the configuration can be more adaptive to user equipment conditions, but the access procedure becomes more complex and slower
Solution Approach 1:
The base station dynamically selects between single-phase and multi-phase configuration based on determined first information. This dynamic approach ensures multi-phase is only used when necessary (based on user equipment conditions), avoiding unnecessary complexity while maintaining adaptability when required.
Solution Approach 2:
The system adjusts the configuration parameter (single-phase vs. multi-phase) based on user equipment characteristics. By changing this parameter dynamically, the system achieves adaptability without permanently increasing complexity, as the complex multi-phase configuration is only activated when conditions warrant it.
3Ease of operation
If a fixed configuration type is used for all user equipment, then the system operation is simpler, but the system performance is suboptimal for different user equipment conditions
Solution Approach 1:
The base station dynamically determines the configuration type based on first information about user equipment conditions. This dynamic operation maintains simplicity in the decision-making process (based on determined characteristics) while improving performance by adapting to different user equipment scenarios.
Solution Approach 2:
The system changes the configuration parameter based on user equipment characteristics to optimize performance. By adjusting this parameter dynamically rather than using a fixed configuration, the system maintains operational simplicity while achieving better productivity across different user equipment conditions.
