摘要

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.

Here, it will be understood that each block of the flowchart illustrations, and combinations of blocks in the flowchart illustrations, can be implemented by computer program instructions. These computer program instructions can be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions specified in the flowchart block or blocks. These computer program instructions may also be stored in a computer usable or computer-readable memory that can direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer usable or computer-readable memory produce an article of manufacture including instruction means that implement the function specified in the flowchart block or blocks. The computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions that execute on the computer or other programmable apparatus provide steps for implementing the functions specified in the flowchart block or blocks.
