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: Methods and apparatuses for transmitting/receiving control information in a system in which multiple frequencies are used to carry multiple services by means of transmission frames, which are constituted of time resources and/or time-frequency resources. Control information regarding frame configuration information is not transmitted over a separate control channel but over a data channel. The service traffic for each non-primary service traffic may include control information for a primary service. Thus, even when a receiver changes the current service to a target service, control information necessary to detect the location of the target service in a frame and demodulate the target service can be acquired, and thus a service change can be made without reading a separate control channel.
