MIMO Antenna Pattern Grouping for Faster Station Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently matching transmitter antenna patterns with receiver antenna patterns in multiple-input multiple-output (MIMO) systems, leading to suboptimal signal quality and efficiency.
Innovation Solution
The technique involves grouping and categorizing antenna patterns by station types in MIMO systems, allowing wireless access points (WAPs) to profile stations and select optimal antenna patterns based on their configuration, thereby reducing the number of patterns to search and improving efficiency.

Engineering Contradiction Analysis
1Reliability
If the WAP searches through all possible antenna patterns to find the optimal match, then the signal quality improves, but the time and computational resources required increase significantly
Solution Approach 1:
The patent segments the complete set of antenna patterns into multiple groups, where each group contains patterns suitable for specific station types (e.g., 1x1, 2x2, 3x3 MIMO configurations). When a station associates with the WAP, the system identifies the station type and searches only within the corresponding group rather than exhaustively searching all patterns. This segmentation reduces the search space while maintaining the ability to find optimal signal quality matches.
2Productivity
If the WAP profiles and categorizes stations by type, then the efficiency of antenna pattern selection improves, but the device complexity increases
Solution Approach 1:
The patent implements preliminary action by establishing station profiles and categorizing stations by type (1x1, 2x2, 3x3, etc.) during the initial association phase. The WAP maintains a database of station types and their corresponding antenna pattern groups. This preliminary classification enables rapid pattern selection during data transmission without requiring complex real-time analysis, as the categorization work is performed upfront when the station first connects.

AI summary
Disclosed herein are apparatuses and a method for improving wireless communication characteristics by matching transmitter antenna patterns to receiver antenna patterns. An embodiment operates by generating a station profile for each of a plurality of stations based on a structure of each of the plurality of stations and an antenna pattern group of each of the plurality of stations. The embodiment then identifies a station profile of a first station from among the plurality of stations based on information received from the first station. Finally, the embodiment searches for an antenna pattern for the first station using the antenna pattern group corresponding to the station profile.
