Abstract: With the advancement of the next-generation mobile communication system (6G), the integrated communication and sensing at the terahertz (THz) band can be a new opportunity for the rmulti-band collaborative communication technology. It is considered that the urgent need for multi-dimensional, multi-granularity, and wide-area sensing information of THz communication and sensing integration technology can facilitate the new development of multi-band collaborative communication technology. Therefore, the multi-band collaboration technology for THz communication and sensing integration is proposed which can improve the performance of THz communication through sensing collaboration and communication collaboration. In addition, the key technologies and challenges of the multi-band collaboration for THz communication and sensing integration through two typical examples are also presented.
