Solution Overview

Problem

Current wireless communication systems in the millimeter-wave band, particularly those using sectorized antennas, face challenges in efficiently supporting multi-user MIMO communications and achieving high data transmission rates due to limitations in channel bandwidth and synchronization requirements.

Innovation Solution

Implementing a wireless station with a plurality of sectorized antennas that operate independently, allowing for unsynchronized MU-MIMO communications and channel bonding to increase channel bandwidth, enabling simultaneous transmission to multiple users without requiring time synchronization between antennas.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If sectorized antennas are used for multi-user communication, then network capacity and data transmission rates are improved, but synchronization requirements and system complexity increase

Engineering Contradiction:
Improvedata transmission rateVSAvoidsynchronization requirement
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent divides the wireless communication system into multiple independent sectorized antennas, each capable of autonomous operation. Each antenna sector functions as an independent transmission unit, eliminating the need for complex inter-antenna synchronization while maintaining high network capacity through parallel multi-user communications.

Inventive Principle:
Principle #1Segmentation

2Productivity

If channel bandwidth is increased to support high data rates, then data transmission rate is improved, but interference between antennas increases

Engineering Contradiction:
Improvedata transmission rateVSAvoidinterference between antennas
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

By segmenting the antenna system into independent sectorized units, each antenna operates autonomously without requiring synchronization with others. This segmentation eliminates inter-antenna interference that would otherwise occur when multiple antennas transmit simultaneously on bonded channels, while still achieving high data rates through parallel transmissions to multiple users.

Inventive Principle:
Principle #1Segmentation

3Productivity

If multiple antennas operate simultaneously for MU-MIMO, then network capacity is improved, but time synchronization between antennas becomes more critical

Engineering Contradiction:
Improvenetwork capacityVSAvoidsynchronization timing
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent implements complete functional segmentation where each sectorized antenna operates as an independent unit with autonomous transmission capabilities. This segmentation removes the need for time synchronization between antennas, as each sector independently manages its own transmissions to assigned users, thereby maintaining high network capacity without synchronization timing constraints.

Inventive Principle:
Principle #1Segmentation
