FIELD: information technologies.
SUBSTANCE: method, network basic station and user communication device are disclosed, which are intended to transfer data in a communication channel with orthogonal frequency division. An antenna array may send a signal decoded with the help of a traditional user device of communication designed for compatibility with a traditional multitude of transmission antennas. A processor 210 may code a subframe of a signal with a traditional multitude of common reference symbols and an additional multitude of common reference symbols related to an antenna array.
EFFECT: provision of maintenance of a required number of UE per subframe for achievement of maximum efficiency for modes of band width of 5 MHz.
