Transfer information such as power control commands. Therefore, the network device sends downlink control information (DCI) to the terminal device, where the downlink control information carries one or more information fields, and each information field indicates information such as the scheduling information and the power control command for the terminal device. It can be considered that the downlink control control information is used to schedule data transmission.
