Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems with mobile relay nodes, dynamic changes in the local environment due to factors like reflection and interference require efficient resource allocation mechanisms to maintain low power consumption and wide coverage.
Innovation Solution
A communication control device and method that dynamically adjusts resource allocation based on local environment changes by recognizing and rewriting slot formats using surrounding environment recognition and slot rewriting mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a mobile relay node is used to expand coverage, then coverage area is improved, but resource allocation flexibility deteriorates due to dynamic environmental changes
Solution Approach 1:
The patent implements dynamic resource allocation where the relay node can change slot formats between downlink and uplink based on real-time channel conditions. This allows the system to adapt to dynamic environmental changes while maintaining expanded coverage, directly resolving the contradiction between coverage area and resource allocation flexibility.
Solution Approach 2:
The patent employs feedback mechanisms where the relay node monitors channel quality indicators and reports to the base station, which then adjusts resource allocation accordingly. This closed-loop control enables the system to maintain optimal resource allocation flexibility despite the challenges of mobile relay operation in dynamic environments.
2Use of energy by moving object
If relay communication is implemented to achieve low power consumption, then power efficiency is improved, but interference increases due to dynamic local environment
Solution Approach 1:
The patent changes the time-domain parameters of resource allocation dynamically, switching between different slot formats based on channel conditions. This allows the relay node to operate efficiently with low power consumption while minimizing interference by adapting transmission characteristics to the current environment.
Solution Approach 2:
The patent implements periodic reevaluation of channel conditions and periodic adjustment of slot formats. This periodic adaptation allows the system to maintain low power consumption through efficient relay operation while reducing interference by regularly adjusting to changing environmental conditions.
