FIELD: information technologies. ^ SUBSTANCE: method includes preparation of multiple subframes for multiple antennas, besides one subframe includes multiple OFDM-symbols in time area and multiple subcarriers in frequency area, at the same time reference signal in one subframe and reference signal in the other subframe are arranged so that reference signals do not overlap in a single subframe, besides reference signal of one subframe and reference signal of the other subframe are serially arranged in adjacent OFDM-symbols or in adjacent subcarriers. ^ EFFECT: improved quality of information transfer. ^ 11 cl, 91 dwg |
