Abstract
A method and apparatus are provided for transmitting and receiving control information in a wireless communication system. A method in a base station includes transmitting, to a terminal, information associated with a number of Control Channel Elements (CCEs) included in control channels; identifying a set of control channel candidates based on an IDentifier (ID) of the terminal and the information associated with the number of CCEs, wherein each control channel candidate includes one, two, four, or eight CCEs; selecting at least one control channel candidate from among the set of control channel candidates; and transmitting the control information to the terminal via the selected at least one control channel candidate.
