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 comprise 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.
