    Abstract: A synchronization method of a user equipment (UE) and a base station (BS) in a wireless communication system, a UE and a BS for establishing synchronization in a wireless communication system, and a non-transitory computer-readable recording medium are provided. The synchronization method of a UE includes detecting a first synchronization signal from a signal received from a BS, detecting repeatedly receivable one or more synchronization signals after the first synchronization signal is detected, based on each of blocks corresponding to a preset synchronization signal mapping pattern on time-frequency resources, combining the one or more synchronization signals, and establishing synchronization with the BS based on a block corresponding to a highest strength of the combined one or more synchronization signals, among the blocks.

    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) during one orthogonal frequency division multiplexing (OFDM) symbol.

    Abstract: The present invention relates to a communication technique, which is a convergence of IoT technology and 5G communication system for supporting higher data transmission rate beyond 4G system, and a system for same. The present invention can be applied to smart services (e.g., smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail businesses, security- and safety-related services and the like) on the basis of 5G communication technology and IoT-related technology. The present invention provides a resource allocation method by a base station comprising the steps of: comparing a transmission time interval (TTI), which is for transmitting data to a terminal, with a preconfigured transmission time interval reference value; if the transmission time interval for the data transmission is shorter than the transmission time interval reference value, determining a resource allocation type for showing frequency resources allocated for the data transmission, and generating control information on the basis of the determined resource allocation type.
