Provided is a wireless communication method and device. Frequency-domain resource allocation and/or bandwidth part configuration is flexibly performed on a terminal device in conjunction with a synchronous signal block, and the performance of a communication system can be raised. The method comprises: a terminal device receives first information sent by a network device, the first information indicating a reference point; and according to the reference point, the terminal device determines a frequency-domain resource and/or bandwidth part configured by the network device for the terminal device.
