Coordination Node Adjusting Resource Patterns for Unsynchronized Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coordination methods for inter-network interference in unsynchronized wireless communication networks fail to effectively eliminate interference, as they assume perfect synchronization among networks, which is difficult to guarantee in real systems.
Innovation Solution
A method and apparatus for adjusting resource patterns in unsynchronized networks by determining synchronization conditions, such as time and frequency offsets, to ensure communication on different resource blocks, thereby avoiding interference. This involves a coordination node that obtains and adjusts resource patterns, notifies networks, and negotiates adjustments to prevent simultaneous interference.

Engineering Contradiction Analysis
1Object-affected harmful factors
If existing coordination methods are used assuming perfect synchronization, then resource patterns can be aligned and inter-network interference can be eliminated, but the method cannot be implemented in real systems where networks are not perfectly synchronized
Solution Approach 1:
The patent introduces dynamic adjustment mechanisms that allow resource patterns to adapt to changing synchronization conditions. The coordination entity continuously monitors synchronization status and dynamically modifies resource allocation patterns to maintain interference elimination effectiveness even when networks become unsynchronized, transforming the static synchronization assumption into a dynamic adaptation capability.
Solution Approach 2:
The patent changes the parameters of resource patterns based on actual synchronization conditions. When networks are found to be unsynchronized, the coordination entity adjusts timing offsets, frequency shifts, and resource block allocations to compensate for synchronization deviations, thereby maintaining interference elimination without requiring perfect synchronization.
2Object-affected harmful factors
If resource patterns are adjusted for unsynchronized networks, then interference can be avoided in real-world scenarios, but the complexity of coordination increases
Solution Approach 1:
The patent introduces a coordination entity that acts as an intermediary between multiple networks. This intermediary collects synchronization status information from各网络, performs centralized calculations to determine appropriate resource pattern adjustments, and distributes the adjusted patterns back to the networks. This intermediary approach simplifies the overall system complexity by centralizing the complex adjustment logic rather than requiring each network to independently handle coordination with multiple others.
Solution Approach 2:
The patent implements feedback mechanisms where the coordination entity continuously monitors synchronization conditions and resource usage, then adjusts resource patterns accordingly. The feedback loop includes collecting synchronization status, evaluating interference levels, modifying resource allocations, and verifying effectiveness, which automates the complexity management and makes the system adaptable without requiring manual intervention.

AI summary
A method for coordinating resources among a plurality of operating networks, including a first operating network and a second operating network performed at a coordination node, which may be a distributed coordination node in the first operating network or a centralized coordination node. The method comprises obtaining a first resource pattern for the first operating network and a second resource pattern for the second operating network. The first resource pattern is coordinated with the second resource pattern such that the first and second operating networks can conduct communications on different resource blocks when the first operating network is synchronized with the second operating network. The method also comprises determining whether the first operating network is synchronized with the second operating network. If it is determined that the first operating network is not synchronized with the second operating network, the method further comprises adjusting at least the first resource pattern.
