Radio Communication Node Dynamic Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio communication systems, particularly in Integrated Access and Backhaul (IAB) networks, do not effectively manage radio resources when simultaneous communication using frequency division duplexing (FDD) is not performed, leading to inefficient use of frequency resources.
Innovation Solution
The implementation of a radio communication node and method that dynamically controls radio resources, using a control unit to manage first and second radio links based on configured resource settings, ensuring appropriate use of radio resources even when simultaneous communication is not performed by allocating additional resources when conditions are met.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If simultaneous communication using FDD is not performed, then radio resources are not efficiently utilized, but resource allocation becomes simpler
Solution Approach 1:
The patent implements dynamic resource allocation where the radio communication node adapts its resource usage based on whether simultaneous communication is configured. The control unit dynamically switches between using only first radio resources (when simultaneous communication is configured) and using both first and second radio resources (when simultaneous communication is not configured), allowing the system to optimize resource utilization according to operational conditions without permanent complexity
Solution Approach 2:
The patent changes the operational parameters of radio resource allocation based on the configuration state. When simultaneous communication is not performed, the system changes from using a restricted set of radio resources to utilizing an expanded set of resources, thereby improving resource utilization efficiency while maintaining manageable complexity through parameter adaptation
2Quantity of substance
If additional radio resources are allocated when simultaneous communication is not performed, then resource utilization improves, but control complexity increases
Solution Approach 1:
The control unit automatically determines and allocates radio resources based on the configuration state without requiring external intervention. When simultaneous communication is not configured, the control unit self-service allocates both first and second radio resources for DU communication, improving resource availability while avoiding the need for complex external control mechanisms
Solution Approach 2:
The control unit is designed with multi-functionality to handle both communication modes (with and without simultaneous communication). It universally manages radio resource allocation by adapting its behavior to the configured mode, thereby increasing available resources without proportionally increasing control complexity through specialized dedicated controls for each mode
3Ease of manufacture
If first radio resources are exclusively used for DU communication, then resource allocation is simplified, but frequency resource waste occurs
Solution Approach 1:
The patent segments radio resources into first radio resources (configured for simultaneous communication) and second radio resources (additional resources). When simultaneous communication is not configured, the system segments resource usage to include both segments, thereby utilizing available frequency resources effectively without complicating the allocation mechanism, as each segment has its designated purpose
4Productivity
If radio resources are dynamically adjusted based on simultaneous communication configuration, then resource efficiency improves, but system complexity increases
Solution Approach 1:
The patent implements a dynamic control mechanism where the control unit adjusts radio resource allocation based on the simultaneous communication configuration state. This dynamic adaptation improves frequency resource efficiency by utilizing available resources appropriately in each mode, while the complexity is managed through a straightforward state-based decision logic rather than complex continuous adjustment mechanisms
