Abstract: Example communication methods and a communications apparatus are described. One example method includes receiving first information by a terminal device, where the first information indicates an identifier of a first frequency domain resource, and the first frequency domain resource is contiguous in frequency domain. When a status of the terminal device is a first state, the terminal device with a network device on a second frequency domain resource based on the first information, where the second frequency domain resource includes a plurality of segments of contiguous frequency domain resources, and the first frequency domain resource is one segment of the plurality of segments of contiguous frequency domain resources. According to the foregoing method, the terminal device may communicate, based on the received first information, with the network device on the second frequency domain resource when the status of the terminal device is the first state.
