Abstract
This application discloses example power control methods and apparatuses. One example method includes receiving, by a first node, first information sent by a second node, where the first information is used to determine a first transmit power, where the first transmit power is a power used when the first node sends downlink information to the second node through a first link, where the first link is a link between the first node and the second node, and where the first node is an upper-level device of the second node. The first node can then determine the first transmit power based on the first information.
Claims16
A power control method, wherein the method comprises:
- receiving, by a first node, first information sent by a second node, wherein the first information is used to determine a first transmit power, wherein the first transmit power is a power used when the first node sends downlink information to the second node through a first link, wherein the first link is a backhaul link between the first node and the second node, wherein the first node is an upper-level relay device of the second node, and wherein the first information comprises a power control parameter P0 and a path loss compensation coefficient α corresponding to the first link;
- and
- determining, by the first node, the first transmit power based on the first information.
A power control method, wherein the method comprises:
- determining, by a second node, first information, wherein the first information is used to determine a first transmit power, wherein the first transmit power is a power used when a first node sends downlink information to the second node through a first link, wherein the first link is a backhaul link between the first node and the second node, wherein the first node is an upper-level relay device of the second node, and wherein the first information comprises a power control parameter P0 and a path loss compensation coefficient α corresponding to the first link;
- and
- sending, by the second node, the first information to the first node.
A power control apparatus, wherein the apparatus comprises:
- a receiver;
- at least one processor;
- and
- one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to:
- receive, by the receiver, first information sent by a second node, wherein the first information is used to determine a first transmit power, wherein the first transmit power is a power used when the apparatus sends downlink information to the second node through a first link, wherein the first link is a backhaul link between the apparatus and the second node, wherein the apparatus is an upper-level relay device of the second node, and wherein the first information comprises a power control parameter P0 and a path loss compensation coefficient α corresponding to the first link;
- and
- determine the first transmit power based on the first information.
A power control apparatus, wherein the apparatus comprises:
- a transmitter;
- at least one processor;
- and
- one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to:
- determine first information, wherein the first information is used to determine a first transmit power, wherein the first transmit power is a power used when a first node sends downlink information to the power control apparatus through a first link, wherein the first link is a backhaul link between the first node and the power control apparatus, and wherein the first node is an upper-level relay device of the power control apparatus;
- and
- send, by the transmitter, the first information to the first node.
