1. An information sending method, comprising:
configuring, by a network device, first information, wherein
the first information comprises:
a first field, and
a second field, wherein
the first field includes information indicating an energy saving state of a terminal device and the information included in the first field enables the terminal device to adjust the energy saving state to a wake-up state or a sleep state, and
the second field includes information indicating a time length in which the terminal device maintains the energy saving state; and
sending, by the network device, the first information to the terminal device, wherein
the first information is in downlink control information format 2-2,
content of the second field is determined based on a time period in which the network device sends data to the terminal device, and
the content of the second field is determined based on the time period in which the network device stops sending data to the terminal device.
