Abstract

A wireless communication method, a terminal device and a communication device. In the method the type or terminal group to which a terminal device belongs is determined. A backscatter signal is sent or a downlink signal is monitored on the basis of a configuration resource corresponding to the type or terminal group to which the terminal device belongs. On the basis of the configuration resource corresponding to the type or terminal group to which the terminal device belongs, the backscatter signal is sent or the downlink signal is monitored, that is, the terminal devices of different types or different groups correspond to different configuration resources.
