Solution Overview

Problem

Existing wireless communication systems face challenges in efficiently managing beam shaping for signals transmitted between base stations and user equipment, particularly in scenarios where obstacles block the line of sight, leading to reduced power efficiency and increased costs compared to traditional repeaters.

Innovation Solution

The implementation of a channel engineering device equipped with an electronically configurable metamaterial, which receives control signaling from a base station to apply specific beam shaping configurations, allowing for real-time adjustment of signal deflection settings to focus, reflect, refract, or filter received signal energy, thereby enhancing communication links.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional repeaters are used to extend coverage beyond line-of-sight, then signal coverage is improved, but power consumption and cost increase

Engineering Contradiction:
Improvesignal coverageVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent replaces traditional active repeaters with a passive electronically configurable deflector that uses metamaterials to manipulate electromagnetic waves. Instead of actively receiving and retransmitting signals (mechanical/electronic system), the deflector passively shapes and directs signal energy using configurable electromagnetic properties of metamaterial units, thereby reducing power consumption while maintaining coverage extension capability

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the electromagnetic parameters (permittivity, permeability) of individual metamaterial units dynamically to achieve different beam shaping configurations. By adjusting these material parameters rather than using fixed passive structures or active repeaters, the system achieves flexible coverage extension with minimal power consumption, as only the deflector configuration changes, not the fundamental operation mode

Inventive Principle:
Principle #35Parameter changes

2Reliability

If beam shaping configurations are adjusted in real-time to track user equipment, then communication reliability is improved, but signaling overhead and complexity increase

Engineering Contradiction:
Improvecommunication reliabilityVSAvoidcontrol signaling complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent pre-configures multiple beam shaping configurations in the deflector before actual communication occurs. When user equipment moves or channel conditions change, the base station simply activates a pre-computed configuration rather than calculating new beam shapes in real-time. This preliminary preparation reduces the computational complexity and signaling overhead required for real-time tracking while maintaining communication reliability

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses index values to reference pre-stored beam shaping configurations rather than transmitting complete configuration data. The base station sends compact index identifiers that point to pre-computed beam shaping patterns stored in the deflector, significantly reducing signaling overhead while enabling rapid switching between different beam configurations to track user equipment

Inventive Principle:
Principle #26Copying

3Adaptability or versatility

If electronically configurable metamaterial deflectors are used instead of passive reflectors, then beam shaping flexibility is improved, but device complexity and cost increase

Engineering Contradiction:
Improvebeam shaping flexibilityVSAvoiddeflector configuration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the deflector into multiple independently controllable metamaterial units or elements. Each unit can be configured separately to achieve different beam shaping functions, allowing the system to handle complex beam shaping tasks by coordinating simple individual units. This segmentation reduces the complexity of controlling each individual element while providing overall system flexibility through coordinated operation of multiple segments

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent designs the metamaterial units to be multi-functional, capable of performing various beam shaping operations (focusing, steering, shaping) through different configuration states. This universal design allows a single type of configurable unit to replace multiple specialized components, reducing overall device complexity while maintaining high beam shaping flexibility through software-controlled configuration changes

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

Methods, systems, and devices for wireless communications are described. A base station may transmit control signaling including a beam shaping configuration to a channel engineering device. The channel engineering device may apply the beam shaping configuration during a time period in which the base station is communicating with a user equipment (UE). The beam shaping configuration may include one or more parameters that modify one or more deflection settings at the channel engineering device to adjust an electronic metamaterial of the channel engineering device to focus received signal energy, reflect received signal energy, refract received signal energy, filter received signal energy, or any combination thereof. The base station and one or more UEs may communicate using the channel engineering device based on the beam shaping configuration.
