The present invention provides a method of superimposing data signals and reference signals in a space division multiple access communication system, a base station of the communication system transmitting the first layer resource block and another layer resource block to a terminal using the same time/frequency resources, reference signals in the first layer resource block and reference signals in the other layer resource block being orthogonal to each other, the method including superimposing data signals transmitted in the first layer resource block at positions of reference signals in the first layer resource block, making a spreading sequence of the superimposed data signals orthogonal to a spreading sequence of the reference signals in the first layer resource block. The present invention can effectively use resources consumed under a multiuser MIMO system and drastically improve the system performance.
