Abstract: A method and apparatus for transmitting or receiving a control channel in a communication system. A method for transmitting control information by a base station includes: configuring a control resource set including a plurality of REGs; interleaving, on a frequency axis, the plurality of REGs included in the control resource set; configuring an REG pool including at least two interleaved REGs; configuring at least one CCE in the REG pool; and transmitting control information through a search space configured by the at least one CCE. Therefore, the present invention improves performance of a communication system.
