Multi-hop Transmission Parameter Segmentation for Latency Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-hop transmission systems experience long data transmission latency due to regenerative relays performing lengthy layer 2 data forwarding processing and independent current-hop scheduling at each relay node, which also causes scheduling time delays.
Innovation Solution
A multi-hop transmission method where a first node obtains second transmission parameter information, determines first transmission parameter information based on this information, and sends service data to a next-hop node, thereby reducing parameter selection range and signaling overheads, and dynamically adapting to instantaneous channel conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If regenerative relays perform layer 2 data forwarding processing, then data transmission can be achieved through relay nodes, but processing time is long causing data transmission latency
Solution Approach 1:
The patent segments the transmission parameter configuration into two parts: centralized configuration of candidate parameter sets (second transmission parameter information) and local selection of specific parameters (first transmission parameter information). This segmentation allows the system to maintain reliable centralized control while enabling faster local decision-making, thereby reducing latency without sacrificing transmission reliability.
Solution Approach 2:
The patent implements preliminary action by pre-configuring candidate transmission parameter sets at relay nodes before actual data transmission. The centralized device prepares multiple candidate parameter sets in advance, which are then stored at relay nodes for quick selection during transmission, eliminating the need for real-time parameter calculation and reducing processing time.
2Adaptability or versatility
If each relay node independently performs current-hop scheduling, then local scheduling flexibility is achieved, but scheduling time is long causing data transmission latency
Solution Approach 1:
The patent applies preliminary action by having the centralized device pre-configure multiple candidate transmission parameter sets that include different scheduling options. Relay nodes can quickly select from these pre-prepared candidates based on current channel conditions, avoiding time-consuming independent scheduling calculations while maintaining adaptability.
Solution Approach 2:
The patent utilizes parameter changes by providing relay nodes with multiple candidate parameter sets that differ in scheduling parameters. The relay nodes can dynamically select different parameter sets based on instantaneous channel conditions, achieving scheduling flexibility through parameter selection rather than complex real-time optimization.
3Adaptability or versatility
If a large parameter selection range is provided for transmission parameters, then optimal parameters can be selected for different conditions, but signaling overheads increase and configuration time increases
Solution Approach 1:
The patent segments the parameter configuration process into centralized candidate set preparation and local parameter selection. The centralized device prepares comprehensive candidate parameter sets once, and relay nodes only need to select from these pre-configured options during transmission, significantly reducing configuration time while preserving parameter selection flexibility.
Solution Approach 2:
The patent implements preliminary action by pre-configuring multiple candidate transmission parameter sets at relay nodes before actual data transmission. This preliminary configuration includes various parameter combinations that can adapt to different channel conditions, allowing fast local selection without increasing signaling overhead during transmission.
