There is herein disclosed a network node of a wireless communication system. The network node has means for selecting a first group of cells. Each cell of the first group of cells is a secondary cell, SCell, for carrier aggregation, CA, on a user equipment, UE, of the wireless communication system. The network node has means for obtaining a first set of labelled data for the first group of cells. The labelled data includes performance information regarding the first group of cells. The network node has means for training a machine learning model for the first group of cells using the first set of labelled data. The machine learning model is configured to be implemented on the network node of the wireless communication system for SCell selection. The network node has means for determining whether the machine learning model meets a performance criteria for at least one cell of the first group of cells.

One method may include collecting network data for training a neural network, train the neural network, using the collected data, to learn a non-discounted cumulative reward Q that evaluates a benefit of including a given beam into a grid-of-beams (GoB), iteratively applying the trained neural network to select at least one optimal beam to include in the grid-of-beams (GoB), and selecting one or more beams from the grid-of-beams (GoB) to transmit to a user equipment or to receive transmission from the user equipment.

Apparatus and method for designing a grid-of-beams using machine learning

In some embodiments, a computing system maintains, in a memory, information on one or more terminal devices, a dictionary of beams and information on a spatial grid. The computing system maps each terminal device to the spatial grid based on up-to-date results of radio measurements and calculates, for each spatial element, a load caused by the one or more terminal devices based on the mapping. The computing system evaluates, for each combination of a beam and a terminal device, a reference signal received power, RSRP, based on results of the radio measurements. The computing system calculates a first map of expected spatial distribution of traffic based on the calculated loads and beam-specific second maps of expected RSRP based on the values of the RSRP. Finally, the computing system causes performing beamforming optimization based on the first map and second maps.
