Logical Channel Mapping for Front-Haul Transport Network Latency

The patent segments the single TDM transmission channel into multiple logical channels with different priority levels. High-priority data is transmitted through dedicated time slots with higher transmission rates and lower delays, while low-priority data uses remaining capacity. This segmentation resolves the contradiction by providing differentiated transmission paths that simultaneously satisfy both high-speed and low-delay requirements for different data types.

The patent applies local quality by assigning different transmission characteristics to different parts of the data stream. Critical control plane data receives high-priority treatment with guaranteed bandwidth and low delay, while user plane data uses best-effort transmission. This localized optimization allows the system to achieve low delay for time-sensitive data while maintaining high overall transmission efficiency.

The patent introduces dynamic resource allocation where transmission resources are not fixed but adaptively assigned based on real-time traffic conditions. The system dynamically adjusts the number and size of time slots allocated to different logical channels, allowing physical transmission resources to be fully utilized when traffic is high while maintaining low delay guarantees when traffic is low. This dynamic approach resolves the contradiction between resource utilization and transmission delay.

The patent creates a multi-functional transmission framework where the same physical transmission infrastructure serves multiple purposes: carrying both control plane and user plane data, supporting both guaranteed service and best-effort service, and adapting to varying traffic patterns. This universality allows the system to achieve high resource utilization across different scenarios while maintaining low delay for time-sensitive transmissions through priority-based scheduling.
