20 Claims

1. A power control method, comprising:

receiving, by a first node, first information from a second node, wherein the first information is used to determine first transmit power, the first transmit power is used by the first node for sending downlink information to the second node via a first link, the first link is a link between the first node and the second node, and the first node is an upper-level node of the second node;

determining, by the first node, the first transmit power based on the first information; and

sending, by the first node using the first transmit power, the downlink information to the second node in a first slot, wherein the first slot is a slot agreed by the first node and the second node in which power control needs to be performed, and the first slot is a multiplexing slot in which downlink transmission is performed by using the first link and uplink transmission is performed by using a second link, wherein the second link is a link between the second node and a third node, and the third node is a lower-level node of the second node or a terminal device.
