Abstract

The present invention relates generally to a method for use in a radio base station of a wireless communications network and to an energy control apparatus (210), more particularly to a method for reducing energy consumption in a multi-antenna multi-port radio base station (220) of a multi-input multi-output wireless communications network. The radio base station (220) is serving a cell (230) and comprising at least two antenna ports (240a; 240b; 240c; 240d) dedicated for that cell (230). The method comprises measuring a load in the cell (230) and comparing the measured load with a defined load value. The method also comprises muting a downlink transmission power transmitted on at least one of the at least two antenna ports (240a; 240b; 240c; 240d) when the measured load is below the defined load value, and thereby reducing energy consumption.

Description

Technical field [0001] The present invention generally relates to a method for use in a radio base station in a wireless communication network, and a device for controlling energy, and more specifically, to a method for reducing multiple input multiple output (MIMO) A method of energy consumption in a multi-antenna multi-port radio base station of a wireless communication network. Background technique [0002] In the past few years, power consumption (ie energy efficiency) has become increasingly important. Undoubtedly, communication technology can make a significant contribution to reducing CO2 emissions by, for example, avoiding travel. At the same time, there is a universal demand to reduce the energy consumption of telecommunication equipment. From a social point of view, this not only contributes to the sustainable development of the world, but also the ability to provide attractive and competitive products and reduce costs are essential. [0003] The cost of operating a wi...
