Solution Overview

Problem

The increased density of user equipment and limited coverage range due to high spectrum frequencies in wireless communication networks lead to inefficiencies in data transmission and reception, particularly in environments where user equipment is not directly connected to the network.

Innovation Solution

Implementing cooperative communication systems where user equipment groups coordinate data transfer through device-to-device links, with active equipment relaying data to passive equipment and base stations, enhancing coverage and capacity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If high spectrum frequencies (mmW, THz) are used for wireless communication, then data transmission speed and network capacity are improved, but coverage range is reduced due to signal loss

Engineering Contradiction:
Improvedata transmission speedVSAvoidcoverage range
Core Design Contradiction:
SpeedVSLength of stationary object

Solution Approach 1:

The patent introduces relay user equipment as intermediary nodes between the network and distant user equipment. These relay devices receive data from base stations via high-frequency connections and forward it to target user equipment, enabling extended coverage while maintaining the benefits of high-speed mmW/THz transmission for the backhaul links.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a multi-dimensional communication architecture by combining device-to-device direct links with relay-assisted indirect links. This adds a spatial dimension to data transmission paths, allowing the network to simultaneously utilize both high-frequency direct connections (where available) and relay-mediated connections (for extended range).

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Quantity of substance

If user equipment density increases to support more devices in close proximity, then network capacity and service coverage are improved, but interference and coordination complexity increase

Engineering Contradiction:
Improveuser equipment densityVSAvoidcoordination complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent implements self-organized relay selection where user equipment autonomously identifies suitable relay devices based on local measurements of signal quality and device capabilities. This distributed decision-making approach eliminates the need for centralized coordination of all device pairs, reducing network controller complexity while supporting high user density.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent segments the dense user equipment population into multiple relay-assisted groups or clusters. Each relay device manages a subset of user equipment, dividing the overall coordination problem into smaller, more manageable sub-problems that can be handled locally without requiring global optimization across all devices.

Inventive Principle:
Principle #1Segmentation

AI summary

User equipment in close proximity may transfer data and control information. For example, the user equipment may exchange data or data sets between each other. Each user equipment can receive and transmit data using radio access technologies. A group of user equipments may include active user equipment and passive user equipment. Active user equipment connects with one or more base stations and transfers data on a wireless communication network via the base station. The active user equipment may communicate with other active user equipment and passive user equipment. Passive user equipment may not connect to any base station and/or the wireless communication network and may communicate with other passive user equipment and active user equipment (e.g., via a sidelink, peer-to-peer, or device-to-device channel).
