1. A method performed by a node in a communications network for determining a first model for use in predicting conditions on carrier frequencies in the communications network, the method comprising:
obtaining measurements of conditions on a plurality of carrier frequencies; and
determining a first model based on the obtained measurements that:
takes as input the conditions on a first subset of the plurality of carrier frequencies; and
outputs a prediction of the conditions on a second subset of the plurality of carrier frequencies, based on the conditions of the first subset of carrier frequencies;
sending details of the first model to a user equipment such that the user equipment may create a local version of the first model on the user equipment and train the local model, based on measurements of conditions on the plurality of carrier frequencies as measured by the user equipment;
receiving from the user equipment an indication of an outcome of the training of the local model performed by the user equipment; and
updating the first model based on the received outcome.
