A mechanism for resource selection in subnetworks that adapts to temporal and spatial interference variations by employing centralized and distributed resource selection modes, determined based on status information such as mobility and communication quality, allowing harmonious coexistence and efficient resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single resource selection mode is used for all subnetworks, then the system is simple to manage, but it cannot meet the extreme performance requirements of different subnetwork scenarios
Solution Approach 1:
The patent implements dynamic resource selection mode determination, where the network device selects between centralized and distributed modes based on real-time status information including mobility levels and interference conditions. This dynamic adaptation allows the system to optimize for reliability in high-mobility scenarios while maintaining efficiency in stable environments, directly resolving the contradiction between reliability and adaptability.
Solution Approach 2:
The patent changes the operational parameter (resource selection mode) based on measured status information such as mobility indicators and interference levels. By monitoring these parameters and switching between centralized and distributed modes accordingly, the system achieves both high reliability when needed and adaptability to varying subnetwork conditions.
2Productivity
If centralized resource selection mode is used, then resource allocation efficiency is improved, but system complexity and signaling overhead increase
Solution Approach 1:
The system dynamically switches between centralized and distributed resource selection modes based on subnetwork status. In scenarios requiring high resource allocation efficiency, the centralized mode is activated with full signaling support. In other scenarios, the distributed mode is used to reduce system complexity and signaling overhead, thus resolving the contradiction between productivity and device complexity.
3Device complexity
If distributed resource selection mode is used, then system complexity is reduced, but ability to meet extreme performance requirements deteriorates
Solution Approach 1:
The patent implements conditional mode selection where distributed mode is used only when status information indicates favorable conditions (low mobility, low interference). When extreme performance requirements are detected through status monitoring, the system dynamically switches to centralized mode, ensuring reliability is maintained while reducing complexity only when safe to do so.
4Reliability
If resource selection adapts to temporal and spatial interference variations, then communication quality is improved, but signaling overhead and processing requirements increase
Solution Approach 1:
The patent monitors status information parameters including interference levels and mobility indicators to determine resource selection mode. By changing the operational mode based on these parameter thresholds, the system improves communication quality when interference is high while minimizing signaling overhead by using distributed mode during low-interference periods.

AI summary
Example embodiments of the present disclosure relate to resource selection for subnetworks. A first device obtains status information associated with a first subnetwork of the radio access network. The first device determines, based at least on the status information from at least a first mode and a second mode, a resource selection mode for selecting a resource for communication within the first subnetwork. The first device transmits, to a second device in the first subnetwork, configuration information at least associated with the determined resource selection mode.
