Method, system and device for information transmission

The invention discloses a method, a system and a device for information transmission, which are used for solving the problem of low signal transmission reliability. In the method, a network device selects a special subframe configuration, and a resource used for transmitting information to an information-receiving terminal is reserved in the special subframe configuration; the terminal is informed of a special subframe configuration message which comprises configuration information of a special time slot and the information on the reserved resource; and the network device adopts the reserved resource to send information to the terminal. As the scheme provided by the invention, only the information-receiving terminal is informed of the reserved resource, and the transmitted information is invisible to an LTE R8 user, so the method, the system and the device cannot influence the conventional LTE R8 user so as to improve the accuracy of the information transmission.
