The standardization of fifth generation (5G) communications has been completed, and the 5G networks are being deployed worldwide. As a result, the visioning and planning of beyond 5G (B5G) and the sixth generation (6G) communications has begun, with an aim to provide communication services for the future demands of the 2030s. In this master class, the series of invited distinguished talks, offered by world-class experts in wireless communications and networks, will provide a vision for B5G/6G that could serve a research guide in the post-5G era. In particular, to support this vision, these talks will discuss the potential application scenarios of B5G/6G. In addition, key potential features of B5G/6G and the required communication technologies will be discussed. Finally, issues beyond communication technologies that could hamper research and deployment of B5G/6G will be explored.
