1. A method for transmitting control information, the method comprising:

  • transmitting information on at least one resource block (RB) for a first control channel via higher signaling;

    transmitting information on a number of orthogonal frequency division multiplexing (OFDM) symbols for a second control channel in a subframe;

    determining a reference signal (RS) associated with the first control channel based on an identifier of a terminal;

    mapping control information for the first control channel and the RS to a part of OFDM symbols within the at least one RB; and

    transmitting the control information and the RS to the terminal,wherein the OFDM symbols for the second control channel are excluded from the part of the OFDM symbols.
