US 2024/0205835 A1 · DOWNLINK POWER CONTROL METHOD AND APPARATUS

Abstract

A downlink power control method and an apparatus. A network management node determines a low energy consumption area, where the low energy consumption area is an area that is within signal coverage of a network node and whose communication distance from the network node is greater than a first preset distance. The network management node generates a power control policy, where the power control policy is used to control the network node to reduce energy consumption for the low energy consumption area, and the network node executes the power control policy to save energy. Energy saving is performed based on loads of some areas in a cell, to maximize an energy efficiency gain.

Claims19

Dependent claims

A downlink power control method, applied to a network management node, wherein the method comprises:

determining a low energy consumption area, wherein the low energy consumption area is an area that is within signal coverage of a network node and whose communication distance from the network node is greater than a first preset distance;
generating a power control policy, wherein the power control policy is used-usable to control the network node to reduce energy consumption for the low energy consumption area;
and
sending the power control policy to the network node.

1 more element
