FIELD: wireless communication.
SUBSTANCE: to transmit a channel state information reference signal (CSI-RS), setting CSI-RS transmission configuration information in a base station, including one or more code division multiplexing (CDM) groups with uniform distribution of resource elements (RE) by frequency in each CDM group. Specified CSI-RS transmission configuration information is transmitted from the base station (BS) to the user equipment (UE). Generating CSI-RS for each antenna port of the base station, modulated by orthogonal coverage code (OCC) in frequency domain (FD) on resource elements in accordance with the discrete Fourier transform (DFT) vector and in the time domain (TD) on one or more OFDM symbols in accordance with the Walsh-Hadamard (WH) code, and transmitting the CSI-RS from the BS to the UE according to said CSI-RS transmission configuration.
EFFECT: high flexibility of the technology of generating and transmitting a channel state information reference signal (CSI-RS).
