Abstract: Provided is a data transmission system of providing preambles of different classes according to a characteristic of a terminal. A terminal having constraints on using a power with respect to a data reception may receive only a preamble of a particular class and thus decrease a power consumption. A general terminal may receive preambles of plural classes and quickly receive data.

Abstract: Provided is a communication system using a space division multi-user multiple input multiple output (SD-MIMO) communication method. A transmission apparatus may transmit, to each of terminals included within a coverage, common control information commonly transmitted to the terminals and individual control information individually transmitted to each of the terminals. The transmission apparatus does not precode the common control information and transmits the non-precoded common control information. The transmission apparatus precodes the individual control information and transmits the precoded individual control information.
