FIELD: radio engineering, communication.
SUBSTANCE: base station and mobile station communicate using a communication multi-input multi-output (MIMO). The base station includes a two-dimensional (2D) antenna array comprising N number of antenna elements configured in a 2D grid. 2D array configured to communicate with at least one subscriber station. The base station also includes a controller configured to transmit N antenna port (AP) of a reference signal of channel state information (CSI-RS), associated with each of the N antenna elements. The subscriber station includes an antenna array configured to communicate with at least one base station. The subscriber station also includes a processing circuit configured to receive a physical shared downlink channel (PDSCH) from the 2D array active in at least one base station. 2D active array antenna includes a number of N antenna elements. Scheme of processing is further configured to estimate full CSI, associated with the N antenna elements.
EFFECT: increased bandwidth.
