## Abstract

A power control method and apparatus, and a device. The method includes: determining, by a network device, whether there is to-be-received uplink data in a first scheduling period on a first receive channel; and in response to determining that there is no to-be-received uplink data in the first scheduling period on the first receive channel, controlling, by the network device, a state of the first receive channel in the first scheduling period to be an off state. This reduces power consumption of the network device.
