FIELD: radio engineering, communications.
SUBSTANCE: invention relates to systems of wireless communication, in particular to a network supporting multiple inputs and multiple outputs (MIMO) and more specifically to transfer of a distributed reference signal (DRS) in a single-frequency network (SFN) via organisation of channels for specific levels. The invention describes using a dedicated reference signal for support of a network MIMO, a distributed MIMO, a coordinated MIMO, coordinated multipoint communication, etc. A symbol of data modulation is sent in the same direction, in which a symbol of pilot signal modulation is sent. Two or more wireless devices may coordinate communication, so that transfers of the same symbol of pilot signal modulation and the same symbol of data modulation are sent to a device in different directions, besides, each direction is related to a wireless device and is designed for a specific mobile device.
EFFECT: cluster-specific or user-group-specific scrambling may be used, and a scrambling code may be communicated before transfer of symbols of pilot signal modulation and symbols of data modulation.
