Abstract: This application provides a communication method and a communication apparatus. A terminal device receives indication information sent by a network device by using higher layer signaling, receives, based on the indication information, a downlink data channel that is sent by the network device and that carries control information, and sends an uplink channel to the network device based on the control information. In this process, a step in which the network device sends a downlink PDCCH to the terminal device and a step in which the network device sends an uplink PDCCH to the terminal device are omitted, and closed-loop service communication is implemented through only one downlink data channel and one uplink channel. There are few signaling-related steps, thereby greatly ensuring service reliability and reducing a latency.

Abstract: This application provides a downlink information transmission method, apparatus, and a device. The method includes: encoding information into a plurality of transport blocks; determining a time-frequency resource used to send each transport block; sending downlink resource indication information to user equipment, where the downlink resource indication information indicates a time-frequency resource location occupied by an Mth transport block; and sending corresponding transport blocks on the time-frequency resources. The user equipment receives the transport blocks based on the downlink resource indication information and decodes the transport blocks to obtain the information, where the downlink resource indication information indicates a resource of only one transport block. A terminal device may determine a time-frequency resource location of another transport block based on a location parameter of the another transport block, and receive and decode the another transport block. Same information bits are carried in a plurality of transport blocks, thereby improving transmission reliability.
