Ma Yiyan from Beijing Jiaotong University provided an update on the progress of "6G Waveform Design Key Technologies". The book extracts four key problem categories from six major scenarios: high-speed mobility, integrated sensing and communication (ISAC), intrinsic intelligence, and wide coverage with low power consumption. The content is organized around waveform performance under channel conditions, highlighting the core question: "How should waveforms be designed, received, evaluated, and unified under scenarios of high-speed mobility, ISAC, intrinsic intelligence, and wide coverage with low power consumption?"

Xie Feng from ZTE shared the creative intent behind "A New Paradigm for 6G Generalized Network Design: Systemic Reconfiguration and End-to-End Empirical Validation". He noted that currently there is no book on 6G design that links strategy and technology. This book, centered on the theme of a new paradigm for 6G generalized network design, constructs for the first time a three-core system of meta-requirements, game theory, and positioning. It aims to present not only interim results but also an inspiring opening chapter.

Su Liyan from Xiaomi introduced "Integrated Sensing and Communication: End-to-End System Design and Key Technologies". In contrast to traditional ISAC research focusing primarily on waveform design, signal processing, and algorithmic optimization, this book places greater emphasis on application scenario requirements, establishing an end-to-end system solution spanning demand analysis, physical layer design, and coordination between the access network and core network.

Chen Yiqi from China Telecom presented the progress of "6G Reconfigurable Intelligent Surface Technologies: Hardware Design, Field Trials, and Standardization". The book follows three main threads: at the hardware design level, it traces the engineering implementation path from unit to full board; at the field trial level, it validates technical feasibility across different frequency bands, multiple scenarios, and various networking modes; at the standardization level, it systematically reviews global standardization progress and clarifies potential evolutionary directions and key engineering constraints.

Zhu Yanze from Shanghai Jiao Tong University introduced that "Reconfigurable Intelligent Surface Communications: Principles, Key Technologies, and Applications" systematically covers the technical background of RIS, hardware design frameworks, channel estimation and beamforming, networking and deployment, field testing and standardization, and looks ahead to frontier directions such as millimeter-wave and terahertz metasurfaces, near-field communications, ISAC, and the integration of RIS with artificial intelligence.

Yuan Yannan from vivo introduced "6G Data Framework". Unlike the "siloed" data collection and non-interoperable data usage in the 5G era, the 6G data framework aims to treat data as a key element of 6G systems, providing full lifecycle management and improving efficiency from data generation to consumption. The book includes use cases and requirements, key technical issues, 6G data framework and solutions, 3GPP 6G data framework research progress, and data-plane prototype demonstrations.
