Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing radio communication systems face increased transmission delays when using multiple radio transmission devices with different radio transmission delays, particularly when combining low-frequency and high-frequency bands, which hinders ultra-reliable and low-latency communications.
Innovation Solution
A radio communication device and system that divides data signals into multiple segments and allocates them based on the transmission delay of each radio transmission path, ensuring efficient distribution across radio transmission devices with varying delays, thereby minimizing overall transmission delay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If divided frames are allocated to radio devices with different radio transmission delays using conventional methods (round robin or communication speed based), then load sharing effect is improved, but transmission delay increases due to frames waiting in devices with large delays
Solution Approach 1:
The patent changes the allocation parameter from simple round-robin or communication-speed-based selection to selection based on total transmission delay characteristics. The allocating unit calculates transmission delays for each radio device and dynamically selects the device with the minimum transmission delay for each divided frame, thereby resolving the contradiction between load sharing and transmission delay.
Solution Approach 2:
The patent introduces dynamic allocation where the selecting unit continuously monitors and calculates transmission delays for multiple radio devices, and adaptively changes the allocation target based on current delay conditions. This dynamic approach allows the system to respond to changing network conditions and maintain optimal transmission delay while preserving load sharing across devices.
2Quantity of substance
If multiple radio lines with different transmission delays are bundled into one virtual line, then bandwidth is expanded, but transmission delay increases due to frames being retained in devices with large delays
Solution Approach 1:
The patent changes the allocation strategy by introducing transmission delay as a key parameter. Instead of uniformly distributing frames across all radio lines, the system calculates and compares transmission delay parameters for each line, allocating frames through the path with minimum delay. This allows the system to maintain expanded bandwidth while avoiding the delay penalty of retaining frames in high-latency devices.
3Productivity
If divided frames are allocated to maximize utilization of radio devices, then device utilization is improved, but transmission delay increases because frames wait for slower devices to complete transmission
Solution Approach 1:
The patent introduces transmission delay as a critical allocation parameter that overrides simple utilization metrics. The allocating unit calculates the total transmission delay for each radio device and selects the device with minimum delay, even if other devices have available capacity. This ensures that device utilization is optimized without sacrificing transmission delay performance.
