Provided is a method for transmitting information, a network device and a terminal device. The method includes that: a time-frequency resource for a downlink control channel of at least one terminal device is determined, the time-frequency resource for the downlink control channel of the at least one terminal device being mapped in a first control region within a bandwidth of a system according to a manner of a frequency domain first and then a time domain; and the downlink control channel of the at least one terminal device is sent through the time-frequency resource for the downlink control channel of the at least one terminal device. According to the information transmission method, network device and terminal device of the embodiments of the application, system performance may be improved.
