Specifically, the processor 920 is configured to determine first DCI and second DCI based on a size of the first DCI, where the first DCI is carried on a power saving signal shared by a plurality of terminal devices including the terminal device, and the second DCI is carried on a terminal device specific power saving signal.

The transceiver 910 is configured to send the first DCI and the second DCI to the terminal device.

For a specific working process and beneficial effects of the network device 900, refer to the descriptions in the embodiment shown in FIG. 5. Details are not described herein again.

The transceiver in the embodiments of this application may also be referred to as a transceiver unit, a transceiver machine, a transceiver apparatus, or the like. The processor may also be referred to as a processing unit, a processing board, a processing module, a processing apparatus, or the like. Optionally, a component that is in the transceiver and that is configured to implement a receiving function may be considered as a receiving unit, and a component that is in the transceiver and that is configured to implement a sending function may be considered as a sending unit. In other words, the transceiver includes the receiving unit and the sending unit. The receiving unit may also be sometimes referred to as a receiver machine, a receiver, a receiver circuit, or the like. The sending unit may also be sometimes referred to as a transmitter machine, a transmitter, a transmitter circuit, or the like.

The memory described in the embodiments of this application is configured to store computer instructions and a parameter for running the processor.
