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.

說明書

FIG. 8 illustrates a terminal including a transmitter, a receiver, and a controller which are configured to perform the above-described embodiments of the disclosure. FIG. 9 illustrates a BS including a transmitter, a receiver, and a controller which are configured to perform the above-described embodiments of the disclosure. A transmission/reception method performed by each of the BS and the terminal is implemented to apply a method for transmitting or receiving a DL control channel and a DL data channel to a 5G communication system according to the above-described embodiments. In order to perform the transmission/reception methods, each of the transmitter, the receiver, and the processor of the terminal, and each of the transmitter, the receiver, and the processor of the BS need to operate according to the embodiments.

Specifically, FIG. 8 is a block diagram illustrating a configuration of a terminal according to embodiments of the disclosure.

As illustrated in FIG. 8, the terminal according to the disclosure may include a terminal processor 801 a terminal receiver 802, and a terminal transmitter 803.
