S-RAN: Semantic-Aware Radio Access Networks

Understand

Semantic communication (SemCom) has been a transformative paradigm, emphasizing the precise exchange of meaningful information over traditional bit-level transmissions.

• However, existing SemCom research, primarily centered on simplified scenarios like single-pair transmissions with direct wireless links, faces significant challenges when applied to real-world radio access networks (RANs).
• This article introduces a Semantic-aware Radio Access Network (S-RAN), offering a holistic systematic view of SemCom beyond single-pair transmissions.
• We begin by outlining the S-RAN architecture, introducing new physical components and logical functions along with key design challenges.
