Under the ground, the foundation.
Push far enough on any of these problems and you find conclusions with no theorem under them. This book works on that layer. It is written in Chinese and open online.
Every claim is labelled by origin: a theorem in the literature, the book’s own derivation, or an open problem.

0Guide6 pagesA map of the field, reading paths, the opening papers, timelines and standards, the eight threads through the book.6Prerequisites11 chaptersWaves and antennas, channels, digital communications, information theory, MIMO, networks, optimization, reinforcement learning, and the new ideas of 6G.17Part I. The Science of Environments10 chaptersWhere channels come from: the map from environment to channel, statistical modelling, channel maps, effective dimension and prediction radius.27Part II. Theorems of the Chain7 chaptersHow channel knowledge becomes service value: Blackwell ordering, the task-knowledge lattice, environment generalization, the cognitive loop, error budgets.34Part III. The Optimization of Networks9 chaptersThe basic limits of resource allocation: nonconvex optimization, sequential decisions, the price of prediction, communication complexity, the cost of layering.43Part IV. The Decision Theory of Swarms9 chaptersHow many agents coordinate: team decisions, phase diagrams of information structure, the information theory of cooperation, learning dynamics, mean fields, network games.52
