Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If centralized mapping method is used to establish backhaul link channels and user radio bearers, then service quality and network reliability are improved, but device complexity and configuration overhead increase
Solution Approach 1:
The patent divides the mapping configuration into two independent parts: centralized control for backhaul link channel mapping and distributed control for user radio bearer mapping. This segmentation allows each part to be optimized independently, reducing overall system complexity while maintaining service quality through coordinated operation of the two mapping methods.
2Device complexity
If distributed mapping method is used for user radio bearers, then device complexity is reduced, but mapping precision and service quality control may deteriorate
Solution Approach 1:
The patent implements feedback mechanisms where nodes report their mapping configurations and status information back to the network controller. This feedback loop enables the distributed mapping to be monitored and adjusted, ensuring that service quality requirements are met while maintaining the simplicity of distributed operation. The feedback allows for dynamic optimization of the mapping precision without increasing operational complexity.
3Adaptability or versatility
If multi-hop network architecture is deployed to extend coverage, then network coverage and adaptability are improved, but loss of information and data transmission reliability may increase
Solution Approach 1:
The patent performs preliminary mapping configuration before data transmission begins. The network controller pre-establishes the mapping relationships between user radio bearers and backhaul link channels, and nodes pre-configure their forwarding behavior. This preliminary setup ensures that data packets are correctly routed through the multi-hop path without loss or misrouting, maintaining transmission reliability while enabling extended network coverage.

AI summary
The present disclosure provides a method and device for configuring a node to transmit and receive data. A second node receives a first message by a first node, wherein the first message comprises at least one of information for determining a channel used by the second node to transmit data received by the second node, or information for determining a radio bearer to transmit data received. Also, the second node transmits the received data mapped to at least one of the channel or the radio bearer used to transmit the data. Through the above method and device, mapping between the received data and transmitted data of each node in a multi-hop network is realized.
