Abstract: In view of the diverse and complex application scenarios of 6G communications, accurate and low-complexity environment information, and channel models are the basis for achieving the 6G wisdom-evolutionary and primitive-concise network. The sensing reconstruction, semantic representation, and application of wireless environments toward 6G predictive wireless environment are investigated. The existing environment sensing techniques and reconstruction algorithms are analyzed,and the semantic representation methods are summarized for a predictive wireless environment. Focusing on the existing channel modeling and prediction challenges, we introduce the 6G network design method for channel online prediction and the predictive radio environment for digital twin communication platform. The key to future predictive wireless environment is to improve the accuracy of wireless environment sensing, enhance the interpretability of wireless environment semantics, and establish a universal system model for 6G channels.
