Abstract: The present invention proposes a hybrid spatial multiplexing (SM) and a space division multiple access (SDMA) technique in a frequency division duplex (FDD) massive multiple-input multiple output (MIMO) system using a two-dimensional planar array antenna, which effectively transmits a channel state information reference signal (CSI-RS) for estimating a downlink two-dimensional space channel using only a limited amount of downlink radio resources, and optimally selects and performs the SM and SDMA techniques in a two-dimensional space channel. To this end, the present invention proposes a technique which defines space resource blocks (SRB) by grouping space elements (SE) having a high spatial correlation between downlink channels in the horizontal dimension and corresponding SEs thereof in the vertical dimension, and transmits CSI-RSs for estimating channels in vertical dimension SEs corresponding to one selected horizontal SE in each SRB every transmit time interval (TTI).
