Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In flexible and mesh networks of 6G communication systems, establishing synchronization quickly becomes challenging when multiple radio communication nodes with different functions and types are connected, leading to increased measurement times due to half-duplex communication restrictions.
Innovation Solution
A radio communication node and method that configures different transmission frequencies and measurement windows for synchronization signals for each radio link or node, utilizing frequency division multiplexing to expedite synchronization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If time direction shifting of synchronization signal transmission timing is applied for each radio communication node, then half-duplex communication conflict is avoided, but measurement time increases with the number of nodes
Solution Approach 1:
The patent transitions from time-domain multiplexing (shifting transmission timing in time direction) to frequency-domain multiplexing (using different transmission frequencies for different nodes). This dimensional change allows simultaneous synchronization signal transmission from multiple nodes without mutual interference, thereby avoiding the measurement time extension that occurs with time-direction shifting in half-duplex systems.
Solution Approach 2:
The patent segments the frequency spectrum into different frequency resources for different radio communication nodes. Each node is assigned a dedicated transmission frequency for synchronization signals, allowing parallel operations across multiple nodes without time-based conflicts. This segmentation enables concurrent synchronization measurements from multiple nodes simultaneously.
2Adaptability or versatility
If multiple radio communication nodes with different functions and types are connected, then network flexibility and coverage are improved, but synchronization establishment becomes more complex and time-consuming
Solution Approach 1:
The patent establishes a universal frequency allocation mechanism where each radio communication node, regardless of its specific function or type, is assigned a dedicated transmission frequency for synchronization signals. This universal approach simplifies the synchronization process by providing a consistent methodology that works across heterogeneous network configurations, thereby reducing the complexity that would otherwise arise from managing multiple node types.
Solution Approach 2:
The patent assigns different transmission frequencies to different radio communication nodes based on their specific characteristics and network roles. This localized frequency allocation optimizes synchronization performance for each node while maintaining overall system simplicity, allowing each node to operate with appropriate frequency resources tailored to its function without increasing overall configuration complexity.
