摘要

This paper proposes an enhanced 6G pervasive channel model (6GPCM) named 6GPCM+, suitable for all 6G frequency bands and scenarios. The 6GPCM+ breaks through the fundamental challenge of pervasive channel modeling across different transmission media, i.e., acoustic waves and electromagnetic waves (including optical waves). Compared with 6GPCM, the 6GPCM+ supports more frequency bands and scenarios including shortwave and all optical wireless communication frequency bands, beyond line-of-sight maritime communications, underwater acoustic communications in shallow water, underground, integrated sensing and communication (ISAC), and multi-frequency scenarios. Additionally, a pervasive large-scale fading channel model is included. Channel statistical properties of 6GPCM+ are compared with those of channel measurement data, demonstrating the accuracy and pervasiveness of 6GPCM+. The proposed model holds significant importance for 6G channel model standardization, as well as the research of common theories, technologies, and system integration constructions of 6G space-air-ground-sea integrated networks.
