Core Concepts
Deep learning offers a promising solution for site-specific beam alignment in 6G, improving efficiency and reliability.
Abstract
The article discusses the inefficiencies of current beam alignment methods in millimeter wave standards.
Introduces the concept of site-specific beam alignment (SSBA) using deep learning for 6G.
Outlines key criteria for DL-aided BA and its implications.
Presents two frameworks for end-to-end learning for SSBA: codebook-based and grid-free approaches.
Provides insights from a unified ray tracing experiment comparing different approaches.
Highlights future research directions and challenges in practical deployment, advanced DL approaches, coverage, network-wide optimization, standardization, and commercial deployment.
