Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing relay transmission systems face inefficiencies in bandwidth utilization, particularly during TDD transmission periods, as surplus bandwidth is not effectively allocated to other communication systems, leading to unused capacity and reduced efficiency.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If fixed bandwidth allocation is used for TDD uplink signals, then bandwidth allocation is simple and stable, but bandwidth utilization efficiency deteriorates when the number of connected ONUs is small
Solution Approach 1:
The patent implements dynamic bandwidth allocation by determining the number of connected ONUs and calculating surplus bandwidth based on actual system state. The bandwidth allocation changes dynamically according to traffic conditions, transitioning from static fixed allocation to adaptive allocation that responds to real-time network status, thereby improving bandwidth utilization efficiency.
Solution Approach 2:
The system changes the bandwidth allocation parameter based on the number of connected ONUs. When the number of ONUs is small, surplus bandwidth is identified and reallocated to downlink signals, effectively changing the bandwidth distribution parameter to match actual traffic needs and improve overall utilization efficiency.
2Loss of energy
If surplus bandwidth is not allocated to other communication systems, then TDD signal transmission is stable, but bandwidth resource waste increases
Solution Approach 1:
The patent ensures continuous useful action by allocating surplus bandwidth to downlink signals of the same communication system. This maintains the stability and reliability of TDD signal transmission while eliminating bandwidth resource waste, ensuring that the optical fiber resources are continuously utilized for meaningful communication tasks.
Solution Approach 2:
The optical fiber bandwidth is made multi-functional by serving both TDD uplink signals and downlink signals. The same physical medium carries different types of traffic at different times, with surplus bandwidth being reallocated to downlink transmissions, thereby achieving universal utilization of the communication resource.
3Productivity
If bandwidth is allocated based on maximum transmission capacity, then system design is simplified, but actual bandwidth utilization deteriorates when traffic demand is low
Solution Approach 1:
The system implements feedback mechanisms by monitoring the number of connected ONUs and their traffic conditions. Based on this feedback information, the bandwidth allocation is adjusted dynamically. The system receives feedback about actual traffic demand and uses it to optimize bandwidth distribution, improving actual utilization while managing complexity through structured feedback processing.
Solution Approach 2:
The patent performs preliminary determination of the number of connected ONUs and calculates potential surplus bandwidth before actual traffic transmission. This preliminary action allows the system to proactively allocate bandwidth efficiently rather than reacting to traffic conditions, improving utilization while keeping the determination process organized and manageable.
