Abstract
The present disclosure relates to a communication technique for fusing a 5G communication system to support a higher data rate than a 4G system with IoT technology; and a system thereof. In embodiments according to the disclosure provide an improved method for transmitting and receiving a control channel. A method performed by a base station according to disclosed aspects includes: transmitting first control area setting information containing first demodulation reference signal (DMRS) setting information for a first control area, transmitting second control area setting information containing second DMRS setting information for a second control area, identifying a third control area where the first control area overlaps with the second control area, and transmitting a DMRS on the basis of the first DMRS configuration information in the first control area including the third control area. A corresponding method performed by a terminal, a base station and a terminal are also described.
