Abstract: Methods and apparatuses are provided for transmitting and receiving control information. A method for transmitting control information, performed by a base station, includes transmitting, to a terminal, information associated with a resource region carrying a control channel; transmitting, to the terminal, by upper layer signaling, a plurality of values associated with control channel candidates, each of the plurality of values corresponding to each of a plurality of numbers associated with CCEs constituting one control channel candidate, wherein the each of the plurality of values indicates a number of control channel candidates to be monitored by the terminal; determining a set of control channel candidates based on an ID of the terminal and at least one of the plurality of values associated with the control channel candidates; 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 at least one selected control channel candidate in the resource region.

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 identifying an offset value and a number of control channel candidates corresponding to a number of control channel elements (CCEs) constituting one control channel candidate; determining indexes of control channel candidates based on the identified offset value and the identified number of control channel candidates; and transmitting the control information to the terminal through at least one of the control channel candidates in a downlink control channel. The determined indexes of control channel candidates are spaced by a value determined based on the transmitted number of control channel candidates

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.
