The integration of 6G and AI includes two aspects: "AI for Networks" and “Networks for AI"

The Driving Force of AI for Networks

Mobile communication technology faces bottlenecks, requiring urgent technological innovation and interdisciplinary integration. AI is a key solution for enhancing network performance.

Traditional communication systems face performance bottlenecks

Conflicts arise between network operation efficiency, complexity, and cost

6G poses more challenging demand metrics

Current technology falls short of meeting 6G's needs

Difficulty in estimating larger scale MIMO channels

Dense base station deployment leads to increased interference

More complex system designs lead to increased energy consumption

Complex routing in heterogeneous equipment networks

Diverse communication scenario requirements are fragmented

air interface

More accurate channel information

More precise positioning

Enhanced interference cancellation capabilities

Enhanced energy efficiency, spectral capacity

network

Improved scene adaptation speed

More balanced traffic scheduling

Faster networking interference avoidance

More refined business identification

The Driving Force of Networks for AI

ITU extends 6G scenarios to ubiquitous intelligence. AI needs to be transformed into new capabilities and services for 6G communication networks to achieve AIaaS

Low latency AI inference/training

Support mobile AI

AI service quality assurance

AI security and privacy protection

6G network inherently provides AI services

Challenges in the Integration of 5G Networks and AI

Fulfilling 6G and AI integration demands, the universality and efficiency of existing AI design methods driven by scenario use cases, plugins, or grafts need to be improved.

Scenario-driven AI

n Design separate AI models for specific air interface and network optimization use cases

Problem: AI models have low generalization, long development cycles, and high costs

n Design different AI service processes for different third-party AI scenarios

Internet of Vehicles

Networks for AI

High-speed intelligent following

smart factory

Real-time multi-agent collaboration

XR/VR

User movement prediction

Problem: The network struggles to rapidly deploy AI services for diverse scenarios

External or grafting AI

n Add AI servers or AI-related network functions to the network, such as NWDAF

Network Management

Problem：It‘s challenging to guarantee real-time, effective, and consistent data. Completing the entire AI process involves high trial and error costs.

n Cloud AI service providers provide best-effort AI services after users submit orders

Problem：Data is only uploaded to the cloud, making it difficult to efficiently leverage the ubiquitous resources within the network, which cannot guarantee the quality and security of AI services

To achieve ubiquitous intelligence, 6G network architecture requires "four transformations"

From external to native and integrated

From best-effort to Al service quality guarantee

From multi elements decoupling to collaboration

From scenario driven to capability driven

1 Driving forces of 6G native AI

6G native AI architecture design 2 and key features

3 6G and Foundation Model

Challenge: As the three fundamental components of AI (data, algorithms and computing) have gained significance on par with network connections, the design of the corresponding architecture, interfaces, and protocols should span the entire AI lifecycle.

个

Resource layer: provide underlying resources

Network function layer: provide specific network function/ network service capabilities

Application and service layer: provide corresponding support f customers' business needs.

Data plane:
manages network data and provides
data services
Computing plane:
manages computing and provides
computing services

Intelligent plane: provides the operating environment for full life-cycle of native AI.

Unlike 5G network, new data plane, smart plane, and computing plane will be defined in 6G network, and traditional control plane and user plane are expected to be extended as well.

Traditional QoS systems primarily emphasize session and connection performance, lacking comprehensive support for diverse requirements；The QoAIS indicator system incorporates security, privacy, autonomy, and resource overhead as new evaluation dimensions to form a standardized AI service quality evaluation system.

QoAIS Guarantee Mechanism

Complete and Unified QoAls Indicator System

Standardized QoAIs Evaluation System

Appropriate Data Collection and Processing

Closed Loop Feedback

Real-Time Response

Designing a native AI protocol that integrates computing and communication is necessary to meet AI‘s connectivity and distributed computing service needs. It is achieved through three dimensions: Management Plane, Control Plane and User Plane

Control Plane: Three Modes of Deep Convergence of Computing and Communication

1 Driving forces of 6G native AI

6G native AI architecture design 2 and key features

3 6G and Foundation Model

As AI enters the era of general intelligence, the emergence of Foundation Models promises a profound transformation in the integration of 6G and AI

Networks for Foundation Models

Foundation Models for Networks

The network serves as a platform to support or provide Foundation Models services

• Provide rich environmental data for foundation models

Offer intent-based services to users

Achieve global collaborative control of intelligent terminals

Foundation Models will enhance mobile network services in aspects such as operations, execution, and verification

Domains	Requirements	Impact onNetworks
NetworkOperations	Multi-modal MachineLearning，LanguageUnderstanding,TextGeneration	Small
NetworkMaintenance	Non-standard DataGovernance，DataAlignment,NaturalLanguage Understanding,Code Generation	Medium
NetworkRunning	Non-standard DataGovernance,ImageGeneration，VideoGeneration	Large

Detecting Failures and Generating Solutions

Orchestrating and Scheduling Task Workflows

• Playing a Vital Role in the Validation Phase

6G native AI facilitates the training of foundation models by providing links and data services during the training process, and supports the inference process with links, computation, and model decomposition/distribution services

Features

AI training services

Foundation models training often needs high-speed fiber optic connections in data centers, making radio network deployment challenging.

Services

Collecting user and network data, preprocessing it, and managing traffic to support model training

Potential gains

6G networks process data efficiently, reducing data transmission and improving cloud AI training for models

Future issues

The required special data analysis techniques? How to efficiently schedule data in a distributed?

AI inference services

Foundation models require significant storage space and powerful AI inference chips, which cannot be met by a single base station.

With proper model segmentation, models can be deployed in wireless networks to offer AI inference services.

In 6G networks, deploying models closer to users can reduce latency

How to balance increased inference latency with reduced transmission latency in 6G networks? Are techniques like model segmentation, compression, and acceleration feasible for models? data be effectively scheduled between nodes? 16

Foundation Models for Networks face significant challenges due to the abundance of structured data and unclear commonalities among different network problems, unlike ChatGPT

Exploring in phases, beginning with the exploration of network operations ai general models Progressing from small-scale to large-scale and from offline to real-time, ultimately investigating the feasibility of unification

Network operation and maintenance data is mainly available at minute/hour intervals from a consistent source, while network operational data is more complex due to varying time intervals, standardization, and data sources, making it harder to acquire.

Data openness and standardization

Difficult data acquisition

Poor data quality

Data openness

Continuously curating and accumulating intelligent network datasets, open to the public, to build a series of innovative smart network ecosystems, and support research

standardization

Collaborate with the industry to jointly formulate new data collection standards and develop a dynamic data collection granularity scheme tailored to specific needs

Industry-wide collaborative data openness
