Abstract: Embodiments of the present invention provide a subframe indication method and a device. A first device determines subframe indication information that indicates at least one of uplink control signaling, downlink control signaling, and data of a first subframe, and sends the subframe indication information to a second device, so that the second device determines a type of the first subframe based on the subframe indication information. In this process, the first device needs to send, to the second device, only the subframe indication information that indicates at least one of parts of the first subframe, and the second device may determine the type of the first subframe based on the subframe indication information, so as to reduce overheads of the subframe indication information.
