Abstract: An apparatus and method is disclosed in relation to antenna arrays. The method may include transmitting a reference signal to one or more remote user terminals from each of a plurality of sub-arrays of an antenna array, each sub-array including a quantity of radiating elements of the antenna array capable of establishing a backhaul link with a remote communications node. The method may also include receiving measurement signals from the one or more remote user terminals, indicative of one or more characteristics of the received reference signals. The method may also include selecting, based on received measurement signals, a first subset of the sub-arrays for backhaul communications with the remote communications node and a second subset of the sub-arrays, including one or more of the remaining sub-arrays, for access communications with the one or more remote user terminals.

Abstract: A method includes confirming, by a user device with a network node, a set of machine learning (ML) functionality adaptation parameters for the user device to perform adaptation of a ML functionality associated with at least one ML model that is used by the user device to perform a radio access network (RAN)-related function. The set of ML functionality adaptation parameters indicate at least one adaptation cycle during which the user device is to perform the ML functionality adaptation and a validity period for which the set of ML functionality adaptation parameters are valid. The method also includes performing, by the user device, adaptation of the ML functionality during the at least one adaptation cycle.
