A method performed by a node in a communications network for predicting energy usage in the communications network. The method comprises obtaining values of network parameters for a plurality of nodes in the communications network and corresponding energy usage measurements for the plurality of nodes, and obtaining a subset of the network parameters that are correlated with the energy usage measurements. The method then comprises training a first model using a first machine learning process to take as input the values of the subset of network parameters for the nodes in the plurality of nodes, and output a prediction of the corresponding energy usage measurements.

Energy usage in a communications network

An omni-radio base station with multiple sector antenna units uses frequency division of sector signals to achieve increased coverage or capacity at reduced cost. Each sector antenna unit has an antenna for receiving a carrier signal associated with an antenna frequency in an available frequency band. At least one of the antenna units has an associated frequency converter that converts the carrier signal received by that antenna unit from the antenna frequency to a different respective frequency. Even though each sector receives the same carrier signal, an output carrier signal associated with each sector is at a different frequency band. A combiner combines the antenna unit carrier signals at different frequencies to create a composite signal for communication to the omni-radio base station. Because the antenna unit signals combined are at different frequencies, they do not interfere as much as they would if they were at the same antenna frequency, which results in less signal loss and degradation in the combiner. The carrier signals are then restored in the base station transceiver from the different respective frequencies to intermediate frequency for further processing.
