    Abstract: Method of terminal, terminal, method of base station, and base station in wireless communication system are provided. Method of terminal in wireless communication system includes receiving, from base station, rate matching information for a physical downlink shared channel (PDSCH) by a radio resource control (RRC) signaling, wherein the rate matching information includes time resource information and frequency resource information; and monitoring a physical downlink control channel (PDCCH) candidate except for a PDCCH candidate overlapped with a resource indicated by the time resource information and the frequency resource information, wherein a search space is defined by a set of PDCCH candidate for an aggregation level, a PDCCH candidate is defined by a set of control channel element (CCE) corresponding to the aggregation level, a CCE is defined by 6 resource element groups (REGs), and a REG is defined by one resource block (RB) daring one orthogonal frequency division multiplexing (OFDM) symbol.

    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 performed by a terminal in a communication system is provided. The method includes receiving, from a base station, demodulation reference signal (DMRS) configuration information using higher layer signaling; receiving, from the base station, downlink control information for transmitting uplink data, the downlink control information including information on DMRS and resource allocation information for the uplink data; identifying a number of at least one DMRS symbol and respective position of the at least one DMRS symbol based on the information on DMRS and resource allocation information; and transmitting, to the base station, the uplink data and the DMRS based on the identified respective position of the at least one DMRS symbol.

    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 of a terminal in a wireless communication system and an apparatus for performing same. The method includes: receiving configuration information of a physical downlink control channel (PDCCH) from a base station; monitoring downlink control information (DCI) having a specific format in a slot, the monitoring based on the configuration information of the PDCCH; determining whether a number of physical downlink shared channels (PDSCHs) received based on the DCI having the specific format in the slot is a number based on a PDSCH reception capability of the terminal; and in case that the number of the PDSCHs received based on the DCI having the specific format is the number based on the PDSCH reception capability of the terminal, stopping monitoring DCI having the specific format in the slot.
