Abstract - The advent of 6G wireless technology promises
network infrastructure capable of delivering the uninterrupted, high-speed, context-aware, and intelligent connectivity that these immersive experiences demand. Consequently, a robust 6G framework with deeply integrated AI [3] is essential to unlock the full potential of these applications.
transformative connectivity, characterized by ultra-low latency, exceptionally high terabit-class data rates, and ubiquitous seamless coverage. This next-generation network is essential for enabling demanding applications such as Artificial Intelligence (AI)-driven Augmented Reality (AR) and immersive Extended Reality (XR), which require stringent performance metrics alongside optimized energy consumption. This paper examines the fundamental requirements of 6G networks, highlighting the vital role of adaptive AI models in achieving intelligent connectivity management. We propose a hierarchical AI architecture comprising a lightweight model for real-time, granular network monitoring and a more complex large AI model for proactive, long-term predictive optimization. These AI-driven mechanisms are key to facilitating seamless handovers across diverse network environments and intelligent Radio Access Technology (RAT) transitions. This approach aims to guarantee sustained terabit-per-second connectivity and significantly improve energy efficiency, crucial for immersive AR experiences. We further explore the necessary architectural innovations, key technical challenges, and a potential roadmap for realizing AI-enhanced connectivity in the forthcoming 6G era.
This paper articulates the core capabilities 6G networks must possess to meet these demanding requirements. Specifically, we emphasize the necessity of embedding AIdriven decision-making mechanisms directly within the network architecture. This integration allows for proactive optimization of network transitions, intelligent resource management, and drastic latency minimization. By incorporating intelligence into every facet of network operation, 6G aims to guarantee seamless handovers across heterogeneous network technologies while simultaneously achieving ultra-low power consumption—a critical factor for the widespread adoption of portable AR devices.

2.1 Lightweight AI Model (Real-time Network Intelligence): Deployed potentially at the Radio Access Network (RAN) edge or within access points, this AI model will perform continuous, granular monitoring of prevailing network conditions. Its responsibilities include real-time evaluation of key performance indicators (KPIs) like data rates (aiming for peaks over 1 Terabit per second [4]), signal strength, interference levels, and user mobility prediction. Furthermore, it must understand the specific Quality of Service (QoS) needs of individual AR applications, such as rendering complexity, required frame rates (e.g., 90-120 fps for immersion), and acceptable latency thresholds (ideally under 10 milliseconds motion-to-photon latency for AR [5]). Based on this real-time analysis, the lightweight AI model must proactively predict the need for seamless handovers between base stations (gNBs) within the same Radio Access Technology (RAT) or anticipate the necessity for a RAT change to maintain optimal performance and user experience. Techniques like reinforcement learning could
1.INTRODUCTION The evolution of wireless communication consistently pushes connectivity boundaries, with each generation unlocking new capabilities. 6G wireless technology is envisioned as a transformative leap, designed to overcome the limitations of current 5G networks and establish unprecedented benchmarks for performance, including ultra-low latency communication potentially targeting endto-end latencies below one millisecond [1]. Unlike its predecessors, 6G must inherently prioritize real-time adaptability and cognitive functions to effectively support the burgeoning ecosystem of next-generation applications, particularly AI-powered Augmented Reality (AR) and immersive XR. With the global AR market projected to reach $340 billion by 2028, reflecting a compound annual growth rate (CAGR) exceeding 40% [2], there is an urgent need for
