Abstract: Disclosed is a method for transmitting radio frequency signals. In the method according to the present invention, a plurality of antenna groups may be arranged for achieving array gain and multiplexing gain at the same time, and the plurality of antenna groups are located far from each other so that they have no correlation, and antennas of the same group are located adjacent to each other so that they have correlation. Accordingly, system capacity as well as capacity of data channel and control channel may be significantly increased through mitigation of inter-cell interference and enhancement of cell edge performance.

Abstract: Disclosed is a method for configuring and transmitting control channel for radio communication. A method for configuring control channel comprises a step of configuring a control channel by using a plurality of tiles, wherein numbers of resource elements in the plurality of tiles are configured to be the same or different. If a method for transmitting control information comprising a small number of bits according to the present invention is used, quality of communication and efficiency of resource may be increased at the same time.
