Solution Overview

Problem

Current wireless communication systems face challenges in providing efficient and reliable connectivity to aircraft due to the three-dimensional nature of air-to-ground communication, which differs from the two-dimensional ground-based systems, resulting in costly and bandwidth-limited connections with limited communication modes.

Innovation Solution

Implementing a beamforming control module that utilizes both fixed and dynamic position information to direct steerable beams from antenna arrays, enhancing initial synchronization coverage and allowing base stations to be spaced farther apart, thereby improving communication efficiency and reliability in air-to-ground networks.

Solution Approach 1:

The patent transitions from two-dimensional ground-based coverage to three-dimensional air-to-ground coverage by incorporating vertical dimension considerations. Base stations are configured to provide coverage in three-dimensional space around aircraft, accounting for altitude and spatial positioning, thereby enabling proper ATG communication coverage.

Solution Approach 1:

The system performs preliminary actions by determining expected relative positions of aircraft and base stations using position information before establishing communication links. Beamforming parameters are pre-calculated based on predicted aircraft trajectories and base station locations, allowing for proactive beam steering and handoff preparation, which improves coverage reliability without requiring denser base station deployment.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The beamforming control module continuously receives position information from aircraft and base stations, and uses this feedback to dynamically adjust beamforming parameters. This closed-loop control ensures that beams are consistently directed toward aircraft, maintaining reliable coverage even with fewer base stations by optimizing the use of available resources.

Inventive Principle:

Solution Approach 1:

The beamforming control module determines expected relative positions of aircraft and base stations using position information before synchronization is needed. By pre-calculating beamforming parameters based on predicted positions, the system enhances initial synchronization coverage without requiring complex real-time processing during the critical synchronization phase.

Inventive Principle:

Solution Approach 2:

The system changes beamforming parameters (such as beam direction, width, and shape) based on position information to optimize synchronization coverage. By dynamically adjusting these parameters according to aircraft and base station locations, the system achieves enhanced coverage while managing processing complexity through parameter optimization rather than structural complexity.
