Core Concepts
Optimizing beamforming for semantic-bit coexisting systems is crucial for maximizing performance and efficiency.
Abstract
The article discusses the challenges and solutions in designing a semantic-bit coexisting communication system. It introduces the concept of Semantic Communication (SemCom) as a key technology for future 6G systems, highlighting its benefits over traditional BitCom. The paper proposes a spatial beamforming scheme to accommodate both SemCom and BitCom users, aiming to maximize semantic rate while ensuring quality-of-service for bit-users. The study addresses resource allocation, interference management, and the need for a coexisting system due to the task-oriented nature of SemCom. Various beamforming algorithms are compared, showing significant performance improvements with the proposed scheme. The research emphasizes the importance of considering both semantic and bit-level communication in future networks.
