Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high-frequency wireless communication systems, especially in 5G networks using millimeter waves, the determination of directivity for transmission and reception is challenged when multiple links with the same frequency are present in close proximity, leading to interference issues that degrade communication quality.
Innovation Solution
A method where the wireless receiver scans and measures reception parameters for multiple directivity settings without active transmission, and the transmitter scans and forms directivity based on high-ranking reception parameters, allowing adaptive determination of transmission and reception directivity to minimize interference from other links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the wireless receiver determines transmission directivity by scanning multiple directivity settings and selecting the one with the highest received power level, then the signal component in reception is maximized, but interference from other wireless links cannot be reduced, leading to degraded communication quality
Solution Approach 1:
The wireless receiver performs preliminary measurement of reception parameters for multiple directivity settings before actual data transmission begins. By pre-scanning and measuring reception parameters for each directivity configuration, the system identifies optimal directivity settings that maximize signal while minimizing interference, allowing informed selection during actual communication operations
Solution Approach 2:
The wireless receiver measures reception parameters for multiple directivity settings and feeds back this information to determine the optimal directivity configuration. The measurement results are used to select transmission directivity that achieves the best signal-to-interference ratio, creating a feedback loop that adapts to the actual communication environment and reduces interference impact
2Productivity
If multiple wireless links use the same frequency in close proximity, then wireless communication density is increased, but interference between links increases, degrading communication quality
Solution Approach 1:
Each wireless link independently determines its optimal directivity settings by measuring reception parameters specific to its local environment. This localized measurement and selection process allows each link to adapt to its unique spatial relationships with other links, maximizing its own signal quality while minimizing interference from neighboring links, thereby enabling high-density deployment
3Measurement precision
If the wireless receiver scans multiple pieces of reception directivity to determine optimal transmission directivity, then the directivity determination accuracy is improved, but the time required for directivity determination increases
Solution Approach 1:
The wireless receiver performs directivity scanning and measurement in advance before actual data transmission begins. By pre-measuring reception parameters for multiple directivity settings and storing these results, the system eliminates the need for time-consuming real-time scanning during actual communication, thereby achieving accurate directivity determination without significant time loss
