SemCom for Metaverse: Challenges, Opportunities and Future Trends

Metaverse is a new paradigm yet to come, gaining popularity in many applications and being developed using a combination of technologies, including Virtual Reality (VR), Augmented Reality (AR), blockchain, and other immersive technologies. One key technology critical to the success of the Metaverse is Semantic Communication (SemCom), which enables efficient and effective communication between humans and intelligent agents. This paper discusses the challenges and opportunities associated with SemCom in the Metaverse and potential future trends. We identify the critical challenges in SemCom, such as context awareness, scalability, and interoperability, and discuss potential solutions to address these challenges. Furthermore, we explore the various opportunities that SemCom can bring to the Metaverse, such as improved user experiences, interactions with virtual assistants, and enhanced data analysis capabilities. Moreover, we examine the emerging trends in SemCom for the Metaverse and highlight some key research directions that will be important in the future.
