Abstract: Disclosed is a 5th generation (5G) or a pre-5G communication system for supporting a data transmission rate higher than that of a 4th generation (4G) communication system such as long term evolution (LTE). An apparatus and a method for performing retransmission in a wireless communication system are provided. A method for operating a transmitting device in a wireless communication system, according to various embodiments of the present disclosure, comprises the steps of: transmitting a plurality of data code blocks (CBs) to at least one receiving device in an initial transmission step; receiving, from the at least one receiving device, feedback information including information for indicating the number of data CBs, from among the plurality of data CBs, for which decoding has failed; and transmitting the number of parity CBs, determined on the basis of the number of data CBs for which the decoding has failed, to the at least one receiving device in a retransmission step. Therefore, the resources required for retransmission can be reduced.

Abstract: Disclosed are a communication scheme and a system thereof for converging an IoT technology and a 5G communication system for supporting a high data transmission rate beyond that of a 4G system. The disclosure can be applied to intelligent services (for example, services related to a smart home, smart building, smart city, smart car, connected car, health care, digital education, retail business, security, and safety) based on the 5G communication technology and the IoT-related technology. A method of receiving a synchronization signal block (SSB) by a UE in a wireless communication system may include: identifying whether a bandwidth of a cell transmitting an SSB which the UE desires to receive corresponds to a first frequency band (FR); when the bandwidth of the cell corresponds to the first frequency band, receiving the SSB using a single carrier waveform; and acquiring synchronization, based on the received SSB; and acquiring system information.

Abstract: The present invention defines a method for controlling uplink transmission power of a terminal in a communication system which is operated by combining heterogeneous systems. Specifically, the present invention defines a method for selectively applying a power control command in order to control uplink power of a terminal in a communication system which is operated by combining an LTE/LTE-A system with a system which applies a new radio access technology, and a method for differently operating power control units depending on whether beam sweeping is applied or not. Such methods efficiently control transmission power of a terminal, and lower the generation of uplink interference signals, thereby improving system efficiency.
