Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radio wave interference occurs between adjacent radio communication systems due to identical resource mapping patterns of synchronization and reference signals, leading to signal collision and degradation of communication quality.
Innovation Solution
Implementing a control mechanism that sets non-overlapping resource mapping patterns for synchronization and reference signals in adjacent radio communication systems, ensuring exclusive scheduling and preventing signal collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If identical resource mapping patterns are used in adjacent radio communication systems, then device complexity is reduced and ease of operation is improved, but signal collision occurs and communication quality deteriorates
Solution Approach 1:
The patent applies local quality by allowing different resource mapping patterns in different geographical locations (adjacent cells). Each base station is configured with a specific resource mapping pattern that is different from its neighbors, creating local differentiation that prevents signal collision while maintaining overall system operation. This is achieved through the control device setting distinct resource mapping patterns for base stations in adjacent cells based on their geographical locations.
2Device complexity
If identical resource mapping patterns are used in adjacent radio communication systems, then device complexity is reduced, but signal collision occurs and communication quality deteriorates
Solution Approach 1:
The patent applies parameter changes by modifying the resource mapping pattern parameters (time and frequency resource allocations) for different base stations. The control device adjusts these parameters based on the geographical location and adjacent cell relationships, ensuring that while the basic structure remains similar, the specific parameter values differ to prevent signal collision. This maintains simplicity while improving reliability.
3Reliability
If non-overlapping resource mapping patterns are set for adjacent radio communication systems, then signal collision is prevented and communication quality is maintained, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by having the control device pre-configure appropriate resource mapping patterns for each base station before operation begins. The control device analyzes the geographical locations and adjacent cell relationships, then assigns suitable non-overlapping resource mapping patterns in advance. This preliminary configuration prevents signal collision without requiring complex real-time adjustments during operation, thus limiting the increase in device complexity.
4Reliability
If non-overlapping resource mapping patterns are set for adjacent radio communication systems, then signal collision is prevented, but device complexity increases
Solution Approach 1:
The patent applies self-service by enabling base stations to autonomously identify their geographical location and determine appropriate resource mapping patterns based on pre-configured information from the control device. Each base station can independently select or adjust its resource mapping pattern to avoid overlap with adjacent cells without requiring continuous complex coordination, thus reducing the overall system complexity while maintaining signal separation.

AI summary
A specific signal in a radio communication system includes at least one of a synchronization signal and a reference signal. A first radio communication system performing radio communication in a first cell uses a first resource mapping pattern as a resource mapping pattern of the specific signal. A second radio communication system performing radio communication in a second cell that is adjacent to the first cell uses a second resource mapping pattern as a resource mapping pattern of the specific signal. The first resource mapping pattern and the second resource mapping pattern are set so as not to overlap with each other through resource mapping pattern control.
