Solution Overview

Problem

In FeD2D communication, conflicts can occur between different wireless links used by terminal apparatuses, leading to inefficient resource allocation and potential communication quality issues due to limited transmission and reception devices available for each link.

Innovation Solution

A communication apparatus and method that involves a control unit to notify resource allocation information for one wireless link to a second apparatus via another wireless link, ensuring coordinated resource management and conflict avoidance between different wireless links.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple communications are performed via mutually different wireless links in FeD2D, then communication capacity is improved, but device conflicts occur between communications

Engineering Contradiction:
Improvecommunication capacityVSAvoiddevice conflict avoidance
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent implements feedback mechanisms where terminal apparatuses report resource allocation information and conflict status to the network device. The network device then adjusts resource allocations based on this feedback to prevent device conflicts while maintaining multiple simultaneous communications. This closed-loop control enables the system to dynamically adapt resource distribution to avoid conflicts between different wireless links.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The network device acts as an intermediary that coordinates resource allocation between multiple terminal apparatuses engaged in different wireless links. By centralizing resource management and mediation, the system can prevent device conflicts before they occur, allowing multiple communications to proceed simultaneously without interference. The intermediary resolves potential conflicts by allocating resources in a coordinated manner across all links.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If resource allocation is optimized for each wireless link independently, then link performance is improved, but overall resource coordination deteriorates

Engineering Contradiction:
Improvelink performanceVSAvoidresource coordination
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent creates a universal resource allocation framework that serves multiple wireless links simultaneously through a single coordinated system. The network device implements a multi-functional resource management mechanism that can allocate resources across different links while maintaining overall coordination. This universal approach prevents device conflicts and ensures efficient resource utilization across all communications without requiring separate independent management for each link.

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

Solution Approach 2:

The patent merges resource allocation decisions for multiple wireless links into a unified coordination process. By combining resource management functions and treating multiple links as an integrated system, the patent achieves both optimized link performance and coordinated resource distribution. The merging of allocation processes allows the system to prevent device conflicts while maintaining high performance across all links through centralized control.

Inventive Principle:
Principle #5Merging (Combining)
