    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: A communication technique and a system for combining IoT technology with a 5G communication system for supporting a higher data transmission rate after 4G systems. The disclosure is applicable to intelligent services based on 5G communication technology and IoT-related technology (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail, security and safety-related services). A method and an apparatus for communication between a base station and a terminal in a millimeter-wave wireless communication system according to an embodiment may enable the base station to multiplex multiple terminals to a single symbol by a single carrier. In addition, according to an embodiment, multiple base stations may support multiplexing of multiple terminals through a single carrier. In addition, the resource efficiency may be improved if the CP size is dynamically adjusted, and if a single carrier is transmitted through a band using multiple carriers.
