Abstract
A method and apparatus are provided for transmitting control information in a base station for a wireless communication system. The method includes transmitting, to a terminal, information associated with a number of Orthogonal Frequency Division Multiplexing (OFDM) symbols carrying control channels; determining a set of control channel candidates based on an IDentifier (ID) of the terminal; selecting at least one control channel candidate from among the set of control channel candidates; and transmitting the control information to the terminal through the selected at least one control channel candidate. Each control channel candidate included in the set of control channel candidates consists of one, two, four, or eight control channel elements (CCEs) existing in the OFDM symbols.
