A method is disclosed for controlling operations of an antenna array comprising two or more controllable sections and antenna ports connected to transceiver circuitry. The method includes determining a scenario of transmission or reception by the antenna array, and configuring the transceiver circuitry responsive to the determined scenario. The scenario is defined in terms of a requirement for a number of users intended as receivers or transmitters, respectively, of the transmission or reception and in terms of one or more of: a path loss requirement, a peak rate requirement, and a traffic capacity requirement. The configuration includes, for the transmission or reception, one or more of: allocating a number of sections of the two or more sections of the antenna array and determining a sub-division of the allocated sections, determining a number of information data layers for multiple-input multiple-output application, and allocating a bandwidth.
