Solution Overview

Problem

Existing wireless communication systems lack flexibility and efficiency, particularly in handling diverse communication scenarios such as enhanced Mobile BroadBand (eMBB), massive Machine Type Communication (mMTC), and Ultra Reliable and Low Latency Communication (URLLC) within a single technology framework.

Innovation Solution

The implementation of Orthogonal Frequency Division Multiplex (OFDM) with Cyclic Prefix (CP-OFDM) in downlink and Discrete Fourier Transform-spread-OFDM (DFT-s-OFDM) in uplink, along with resource grid configurations and carrier aggregation, enhances communication flexibility and efficiency by optimizing resource allocation and channel access procedures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single communication structure is used, then system simplicity is maintained, but communication flexibility and efficiency are limited

Engineering Contradiction:
Improvecommunication flexibilityVSAvoidcommunication structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic communication structures by allowing the network to switch between different communication modes (relay-based and direct) based on real-time conditions. The relay communication structure is activated when needed for extended coverage or improved reliability, while direct communication is used when conditions permit, creating a flexible adaptive system rather than a static single-structure approach

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent creates a universal communication framework that can perform multiple functions through a single integrated system. The base station and relay devices can simultaneously handle both relay communication and direct communication tasks, and the system can adapt to serve different communication scenarios (eMBB, mMTC, URLLC) using the same infrastructure, thereby achieving versatility without proportionally increasing structural complexity

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

2Productivity

If resource allocation is optimized for specific scenarios, then efficiency for those scenarios improves, but adaptability to other scenarios decreases

Engineering Contradiction:
Improvecommunication efficiencyVSAvoidscenario adaptability
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent employs parameter changes by dynamically adjusting communication parameters such as resource allocation, modulation schemes, and relay selection based on the specific scenario requirements. For eMBB, resources are allocated to maximize throughput; for mMTC, parameters are optimized for massive device connectivity; for URLLC, parameters are adjusted to ensure low latency and high reliability. This allows the system to achieve high efficiency for each scenario while maintaining adaptability through parameter flexibility

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent segments resource allocation into scenario-specific configurations while maintaining a unified management framework. Different resource pools, transmission parameters, and relay configurations are prepared for different scenarios (eMBB, mMTC, URLLC), allowing the system to activate the appropriate segment for each communication type, thereby achieving both scenario-optimized efficiency and overall adaptability

Inventive Principle:
Principle #1Segmentation
