    Abstract: Disclosed are: a communication technique for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system; and a system therefor. The present disclosure can be applied to intelligent services (for example, smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, security and safety-related services, and the like) on the basis of 5G communication technology and an IoT-related technology. The present invention provides a method by which a base station transmits a DM-RS in a wireless mobile communication system supporting a first transmission time interval (TTI) and a second TTI, comprising the steps of: checking a TTI used in a downlink control channel transmission; determining, as a first pattern, a DM-RS for the downlink control channel if the TTI is the first TTI, and determining, as a second pattern, a DM-RS for the downlink control channel if the TTI is the second TTI; and transmitting, to the terminal, the downlink control channel and the DM-RS according to the determination.

    Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method for transmitting uplink control information in a wireless communication system is provided. The method includes receiving configuration information on a plurality of bandwidth parts (BWPs) from a base station; receiving downlink control information and downlink data from the base station; receiving BWP adaptation information which indicates a change of an active BWP from the base station; identifying an uplink control channel resource for transmitting acknowledgement information in response to the downlink data; and transmitting the acknowledgement information on the identified uplink control channel resource to the base station.

    Abstract: The present disclosure relates to a communication technique for converging IoT technology with a 5G communication system for supporting a higher data transmission rate after a 4G system and, and a system therefor. The present disclosure can be applied to intelligent services on the basis of 5G communication technology and IoT-related technology (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail business, security and safety-related service, etc.). When a particular frequency at which an LTE-A system operates is included in an unlicensed band, a situation may occur where some subframes of the LTE-A system cannot be used. When a synchronization signal and a discovery reference signal to be transmitted by a base station collide with a detection and channel occupation operation for the unlicensed band, the timing of the detection and channel occupation operation for the unlicensed band may be adjusted in order to solve the problem of the collision.
