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.

Abstract: A data transmission method includes transmitting, by a first communications apparatus, first data with a second communications apparatus on a first frequency resource. The method also includes sending, by the first communications apparatus, control information to the second communications apparatus. The control information is used to schedule a part or all of the first data transmitted between the first communications apparatus and the second communications apparatus on a second frequency resource. A first transmission mode supported by the first frequency resource is different from a second transmission mode supported by the second frequency resource. Alternatively, the first transmission mode is the same as the second transmission mode, and a first feedback quantity supported by the first frequency resource is different from a second feedback quantity supported by the second frequency resource.

Abstract: Embodiments provide a communication method, a network side device, and a terminal device. When a quantity of minimum scheduling time units in one time of scheduling performed by a network side device is S, and the network side device and a terminal device transmit data in a first transmission mode, a target scheduling rule can be determined by the terminal device from N scheduling rules. The scheduling rule includes at least one of a quantity T of transport blocks in one time of scheduling and a mapping relationship between T transport blocks and S minimum scheduling time units in one time of scheduling. The first transmission mode is a single-antenna transmission scheme or a multi-antenna transmission scheme. Communication can be performed, by the network side device, with the terminal device according to the target scheduling rule. In this way, proper scheduling rules can be selected to adapt to different scenarios.
