Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks face challenges in optimally assigning serving nodes to terminals, as existing methods do not effectively consider antenna gain and beamforming capabilities, leading to suboptimal radio conditions and interference suppression during load balancing and handover processes.
Innovation Solution
A first node with an electrically adjustable antenna radiation lobe is used to evaluate communication properties, including antenna gain, and adjust the antenna radiation pattern to direct beams towards the current or candidate serving nodes, enabling improved beamforming and load balancing by considering favorable antenna configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional serving node assignment methods are used, then network operation is maintained, but antenna gain and beamforming capabilities are not considered leading to suboptimal radio conditions
Solution Approach 1:
The patent changes the evaluation parameters for serving node assignment by incorporating antenna gain and beamforming capabilities. The first node evaluates communication properties including antenna gain values for different serving node candidates, and uses these parameters to determine optimal serving node assignment, thereby improving both radio conditions and spectrum efficiency.
2Reliability
If serving node assignment is changed to optimize radio conditions, then communication quality improves, but network complexity increases due to additional evaluation requirements
Solution Approach 1:
The first node performs self-evaluation of communication properties with different serving node candidates by measuring antenna gain values. The node autonomously evaluates its own communication capabilities towards various serving nodes and uses this self-generated information for serving node selection, reducing the need for complex external evaluation mechanisms.
3Object-affected harmful factors
If antenna radiation lobe is adjusted to direct beams towards serving nodes, then interference suppression improves, but device complexity increases due to electrically adjustable antenna requirements
Solution Approach 1:
The patent employs electrically adjustable antenna radiation lobes that can be dynamically steered towards different serving node directions. The antenna system electronically adjusts its radiation pattern without mechanical movement, enabling adaptive beamforming and interference suppression while maintaining system reliability.
4Stability of the object's composition
If load balancing is performed without considering antenna gain, then network stability is maintained, but spectrum efficiency is reduced
Solution Approach 1:
The first node performs preliminary evaluation of communication properties including antenna gain values before making serving node assignment decisions. By pre-evaluating the antenna gain characteristics towards different serving node candidates, the system can make informed load balancing decisions that optimize spectrum efficiency while maintaining network stability through careful selection of target serving nodes.
