The present invention frequency division doubles (FDD: Frequency-Division Duplex) giant multi-antenna environment (massive MIMO: massive Multi-Input Multi-Output) using a technique related to a method and apparatus for supporting multiple users (multi-user) that a communication method of a terminal in a MIMO system according to an embodiment of the present invention, estimating a channel; Calculating the estimated channel and having a minimum correlation (correlation) first precoding matrix indication; It may comprise; transmitting the calculated first precoding matrix indication to the base station. According to one embodiment of the invention, the large multi-antenna system, the terminal haejueo feedback to a base station close to the precoder the channel space (null space) of a channel other than the near precoder and their channel frequency division doubles large multi-antenna ( massive FDD MIMO) it is possible to reduce the inter-user interference in the environment.
