    Abstract: The present disclosure relates to a communication technique for merging, with an IoT technology, a 5G communication system for supporting a higher data transmission rate than a 4G system, and a system therefor. The present disclosure can be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail businesses, security- and safety-related services, and the like) on the basis of a 5G communication technology and an IoT-related technology. A terminal according to an embodiment of the present disclosure can prepare signal processing before receiving a data signal by storing, in a memory, information pre-configured from a base station and reconstruct a signal by sequentially and rapidly processing time symbols in sample units, thereby performing fast signal processing on a single carrier.

    Abstract: Disclosed are a communication technique for merging, with an IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system, and a system therefor. The 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 IoT related technology. A new radio access technology (NR) system, which is novel 5G communication, is designed such that various services can be freely multiplexed in time and frequency resources, thereby enabling channel state information based on an aperiodic CSI-RS or a synchronization signal to be transmitted and received. According to the present invention, a base station in a wireless communication system transmits channel state information reference signal (CSI-RS) configuration information to a terminal, transmits channel state information feedback configuration information to the terminal, transmits CSI-RS trigger information to the terminal, aperiodically transmits a CSI-RS to the terminal according to the CSI-RS trigger information, and can receive, from the terminal, channel state information generated on the basis of the transmitted CSI-RS, wherein the CSI-RS is configured according to the CSI-RS configuration information, and at least a part of the configured CSI-RS can be transmitted by the CSI-RS trigger information.

    Abstract: The present disclosure relates to a communication technique for converging IoT technology with a 5G communication system for supporting higher data transmission rates after 4G systems, and a system for same. The present disclosure may be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail businesses, security and safety-related services, and the like) based on 5G communication technology and IoT-related technology. The present invention discloses a method and device for efficiently transmitting control information for multiple pieces of data transmitted to a terminal in order to efficiently support cooperative communication. Specifically, a method for a terminal in a wireless communication system to receive downlink data includes steps for: detecting first downlink control information (DCI) scrambled by a cell-radio network temporary identifier (C-RNTI); detecting second DCI scrambled by an RNTI for cooperative communication, when the first DCI has been detected; determining, when the second DCI has been detected, whether the second DCI is valid; and receiving, according to the first DCI and the second DCI, two or more pieces of downlink data when the second DCI has been determined to be valid.
