Engineering Contradiction Analysis
1Measurement precision
If distributed coordination between L2 nodes is implemented using traditional multi-round message exchange, then resource allocation accuracy can be improved, but communication overhead and coordination time increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple message types with different recipient sets and content structures before coordination is needed. When a triggering condition occurs, the appropriate pre-defined message type is selected and sent immediately, eliminating the need for multi-round exchanges to determine message structure. This allows the system to achieve accurate resource allocation with a single message exchange by having all coordination scenarios pre-planned.
Solution Approach 2:
The patent implements dynamics by making the message recipient set variable based on the triggering condition. Different message types target different recipient groups (e.g., neighboring L2 nodes, core network, specific UEs), allowing the system to adapt the coordination scope dynamically. This dynamic message routing enables accurate resource allocation decisions to be made and communicated efficiently to the appropriate parties in a single exchange.
2Productivity
If comprehensive coordination information is exchanged between L2 nodes, then resource allocation efficiency can be improved, but message complexity and processing overhead increase
Solution Approach 1:
The patent applies segmentation by dividing coordination information into distinct message types, each containing only the specific data elements relevant to its purpose. For example, some messages contain only resource allocation information, while others contain interference coordination data or UE-specific parameters. This segmentation allows L2 nodes to process only the necessary information for each coordination scenario, improving efficiency without requiring nodes to handle all possible coordination data types simultaneously.
Solution Approach 2:
The patent implements local quality by tailoring the content and recipient set of each message type to the specific coordination needs. Different message types have different levels of detail and different target audiences based on the triggering condition. This allows each L2 node to receive and process only the locally relevant information needed for its specific coordination task, reducing overall system complexity while maintaining high resource allocation efficiency.
3Reliability
If L2 nodes perform frequent coordination checks, then interference management can be improved, but energy consumption increases
Solution Approach 1:
The patent applies periodic action by implementing event-triggered coordination where L2 nodes monitor for specific triggering conditions (such as interference thresholds or resource allocation changes) and only initiate message exchange when such events occur. This periodic monitoring approach, combined with event-driven activation, ensures reliable interference management through regular checks while consuming energy only when coordination is actually needed, rather than maintaining continuous communication.
Solution Approach 2:
The patent implements self-service by enabling L2 nodes to autonomously determine when coordination is necessary based on locally monitored triggering conditions. Each node independently evaluates its own state and environment, initiating coordination message exchange only when predefined conditions indicate interference or resource allocation issues. This self-service mechanism ensures reliable interference management through autonomous monitoring while minimizing energy consumption by avoiding unnecessary coordination communications.
