A method and apparatus may include determining that a triggering has occurred. The triggering corresponds to a triggering of a formation of a multiple-input and multiple-output arrangement. The multiple-input and multiple-output arrangement comprises a grouping of user antennas and an antenna of the apparatus, and the apparatus is located at an existing infrastructure. The method may also include receiving data traffic information. The data traffic information comprises information that indicates an amount of data traffic that is requested by users of the user antennas. The method may also include forming the multiple-input and multiple-output arrangement based on the received data traffic information.
