    Abstract: The present disclosure relates to a communication technique and system thereof that fuses a 5G communication system with IoT technology to support a higher data rate than a 4G system. The present disclosure may be applied to an intelligent service (for example, a smart home, a smart building, a smart city, a smart car or a connected car, health care, digital education, retail, a security and safety related service, etc.) on the basis of 5G communication technology and IoT-related technology. According to the present invention, a method of a terminal in a wireless communication system comprises the steps of: detecting a synchronization signal block at a synchronization signal block candidate position which is determined according to a subcarrier interval of the synchronization signal block; and performing synchronization on the basis of the synchronization signal block.

    Abstract: The present disclosure relates to a communication technique for combining IoT technology with a 5G communication system for supporting a higher data transmission rate than 4G communication systems and to a system therefor. The present disclosure may be applied to intelligent services, such as smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail businesses, and security- and safety-related services on the basis of 5G communication technology and IoT-related technology. Disclosed are a method and apparatus for retransmitting only the code block, in a transport block, requiring retransmission and not the entire transport block if retransmission of the initially transmitted transport block is necessary.

    Abstract: Apparatuses (including base stations and terminals), systems, and methods for supporting both wideband and narrowband communications are described. In one aspect, a base station supporting first type terminals operating on a first bandwidth and second type terminals operating on a second bandwidth is described, having an information formatter, a transceiver, and a controller. The information formatter generates a Low-end Master Information Block (L-MIB) and a Low-end System Information Block (L-SIB), which are transmitted by the transceiver to first type and second type terminals. The L-MIB includes control information on an L-subframe configuration for supporting a second type terminal and a sub-band configuration of the L-subframe, while the L-SIB includes information on downlink reception and uplink transmission of the second type terminal. When the base station receives a Random Access Channel (RACH) preamble request from one of the terminals, the base station performs the random access procedure.

    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 is provided. The method includes receiving downlink control information (DCI) including frequency domain resource allocation information on a physical downlink control channel (PDCCH) from a base station, identifying an allocated resource for transmitting or receiving data based on the frequency domain resource allocation information, and transmitting or receiving the data on the allocated resource. When the frequency domain resource allocation information is based on a first bandwidth part of a first bandwidth and the DCI is for a second bandwidth part corresponding to a second bandwidth, the allocated resource is identified by applying a scaling factor based on the first bandwidth and the second bandwidth.
