    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: 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 terminal in a wireless communication system and method thereof are provided for receiving a channel state information reference signal (CSI-RS). The method includes receiving configuration information on a CSI-RS, the configuration information including information on a transmission bandwidth of the CSI-RS; identifying a transmission bandwidth of a synchronization signal block (SSB); and receiving the SSB and the CSI-RS. When the SSB and the CSI-RS are configured to be allocated in an orthogonal frequency division multiplexing (OFDM symbol), the transmission bandwidth of the SSB and the transmission bandwidth of the CSI-RS are not overlapped.

    Abstract: Methods and apparatuses for measurement reference signals and synchronization signals. A user equipment (UE) includes a transceiver and a processor operably connected to the transceiver. The transceiver is configured to receive a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a primary broadcast channel (PBCH). The processor is configured to decode cell identification information from at least the PSS and the SSS and to decode a master information block (MIB) from the PBCH. The PSS, the SSS, and the PBCH are time-division multiplexed. A same set of sequences are used for the PSS and the SSS for different carrier frequencies and different sub-carrier spacing values.

    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. The present invention is a method by which a base station transmits a signal in a wireless communication system for efficiently performing an initial access procedure of a terminal, the method comprising the steps of: generating the synchronization signal on a basis of subcarrier spacing used in the synchronization signal; and transmitting the synchronization signal to the terminal.

    Abstract: A method and system for resource allocation is provided. A method includes identifying bit map information on a set of resource blocks associated with a control channel for a UE, through radio resource control (RRC) signaling from a base station; receiving, from the base station, control information for downlink data on the control channel identified based on the bit map information; and receiving, from the base station, the downlink data on a data channel based on the control information. The control information is received on at least one control channel resource, which is included in the set of resource blocks. A search space for the control channel of the UE is defined based on an aggregation level, a number of the at least one control channel resource included in the set of resource blocks, and a number of a candidate associated with the control channel.
