Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beam management systems for 5G wireless communications face challenges in optimizing antenna gains due to the use of fixed matching networks, which can result in suboptimal coverage for certain traffic beams, especially with increased mutual coupling among antenna elements.
Innovation Solution
Implementing multiple matching networks, each optimized for specific beam indices to maximize antenna gains and improve system performance, while also considering criteria such as minimizing side-lobe values for MU-MIMO implementations.

Engineering Contradiction Analysis
1Device complexity
If a fixed matching network is used for all beam indexes, then device complexity is reduced, but antenna gain is suboptimal for certain traffic beams
Solution Approach 1:
The patent applies dynamics by transitioning from a fixed matching network to a dynamic selection mechanism where multiple matching networks are available and the appropriate one is selected based on the current beam index. This allows the system to adapt its matching characteristics dynamically to optimize antenna gain for different beam directions while managing complexity through selective rather than universal application.
Solution Approach 2:
The patent changes the parameter of matching network configuration from a single fixed state to multiple configurable states, each optimized for specific beam indexes. By varying the matching network parameters according to the beam index, the system achieves optimal antenna gain across different traffic beams without requiring maximum complexity for all scenarios simultaneously.
2Power
If multiple matching networks are assigned to different beam indexes, then antenna gain is maximized, but device complexity increases
Solution Approach 1:
The patent segments the matching network functionality by creating multiple specialized matching networks, each optimized for specific beam index ranges. Instead of one complex universal matching network, the system divides the functionality into multiple simpler, purpose-specific networks that can be selected based on the current beam index, thereby managing overall complexity while maximizing antenna gain for each segment.
Solution Approach 2:
The patent implements multi-functionality by designing a matching network system that can serve multiple beam indexes with different characteristics using a set of standardized matching networks. Each matching network in the set can be universally applied to its designated beam indexes, providing optimized performance across multiple functions without requiring completely separate designs for each beam.
3Reliability
If matching networks are optimized for specific beam indexes, then coverage is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies local quality by optimizing each matching network for its specific target beam index range rather than requiring all matching networks to meet the same high precision standards for all beams. Each matching network is designed with appropriate precision levels tailored to its local function, reducing overall manufacturing precision requirements while maintaining reliable coverage for each specific beam direction.

AI summary
A method is provided. The method includes determining a set of beam indexes including a first beam index and a second beam index; and determining a set of candidate matching networks. The method further includes performing an assigning step, where the assigning step includes: (a1) assigning a first matching network from the set of candidate matching networks to a first beam index; and (a2) assigning a second matching network from the set of candidate matching networks to a second beam index. The first matching network is different from the second matching network.
