Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication networks face challenges in maintaining reliable connections for user devices due to interference, channel aging, and instability, particularly when switching between different base stations or network operators, leading to interrupted communication.
Innovation Solution
A multi-link user device (ML-UE) equipped with multiple antennas forms independent spatial or directional beams to establish simultaneous connections with multiple network elements, allowing parallel communication links that can be managed independently without informing the network, enhancing reliability and data rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a user device establishes a single wireless communication link with one base station, then the device complexity is low, but the communication reliability deteriorates due to interference, channel aging, and instability
Solution Approach 1:
The patent segments the single communication link into multiple independent spatial links using multiple antenna beams. Each beam forms an independent communication path to different network elements, allowing the device to maintain multiple simultaneous connections rather than relying on a single vulnerable link.
Solution Approach 2:
The patent introduces spatial dimensionality by utilizing multiple antennas to create directional beams in different spatial directions. This transforms a two-dimensional planar communication approach into a three-dimensional spatial multiplexing approach, enabling simultaneous independent links through spatial separation.
2Reliability
If a user device establishes multiple independent wireless communication links using multiple spatial beams, then the communication reliability improves, but the device complexity increases
Solution Approach 1:
The patent makes the antenna system universal by enabling it to perform multiple functions simultaneously - forming multiple independent spatial beams for different network elements using the same physical antenna array. This multi-functionality allows a single device to maintain multiple independent links without requiring separate hardware for each connection.
Solution Approach 2:
The patent changes the operational parameters of the antenna system by dynamically adjusting beam directions, spatial configurations, and transmission parameters for each independent link. This allows the system to adapt to different network conditions and optimize performance across multiple simultaneous connections.
3Productivity
If simultaneous connections to multiple network elements are established, then the data rate increases, but the interference between links increases
Solution Approach 1:
The patent applies local quality by directing each spatial beam with focused energy toward its specific target network element. Each beam is optimized locally for its specific direction and target, concentrating transmission power where needed while minimizing spill-over interference to other links through precise spatial filtering.
