Solution Overview

Problem

Current mobile communication systems face challenges in efficiently managing diverse traffic types and services, such as delay-critical voice and video, background services, and energy-efficient sensor data, within the same network, leading to inefficient resource utilization and increased latency.

Innovation Solution

A unified frame structure for wireless communication systems that distinguishes and supports three types of traffic: high spectral efficiency for delay-critical data, sporadic machine-type communication, and energy-efficient sensor data, using different carrier frequency bands within the same system to optimize resource allocation and reduce unused resources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a unified frame structure is used to support diverse traffic types, then resource utilization efficiency is improved, but system complexity increases

Engineering Contradiction:
Improveresource utilization efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The unified frame structure is segmented into multiple sub-frames, where each sub-frame is configured to handle specific traffic types (e.g., delay-critical traffic in one sub-frame, background traffic in another). This segmentation allows the system to efficiently manage diverse traffic requirements while maintaining a unified overall structure, resolving the contradiction between resource utilization efficiency and system complexity.

Inventive Principle:
Principle #1Segmentation

2Productivity

If different carrier frequency bands are used for different traffic types, then spectral efficiency is improved, but device complexity increases

Engineering Contradiction:
Improvespectral efficiencyVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

Different carrier frequency bands are assigned to different sub-frames based on the specific requirements of each traffic type. For example, higher frequency bands with better spectral efficiency are allocated to delay-critical traffic, while lower frequency bands are used for background traffic. This local quality approach optimizes spectral efficiency for each traffic type while managing device complexity through structured resource allocation.

Inventive Principle:
Principle #3Local quality

3Reliability

If radio resources are permanently reserved in a connection-oriented manner, then service reliability is improved, but resource utilization efficiency deteriorates

Engineering Contradiction:
Improveservice reliabilityVSAvoidresource utilization efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system implements dynamic resource allocation within the unified frame structure, where radio resources are reserved for connection-oriented services when needed but can be dynamically released and reallocated to other traffic types when not in use. This dynamic approach maintains service reliability for connection-oriented traffic while improving overall resource utilization efficiency by eliminating permanent reservations.

Inventive Principle:
Principle #15Dynamics
