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 provides a method and an apparatus which can achieve accurate time and frequency synchronization while reducing system load, in line with the design requirements for a 5G communication system. Particularly, the present invention provides a method for acquiring time and frequency synchronization by a terminal in a communication system, the method comprising the steps of: receiving a first synchronization signal from a base station; receiving a second synchronization signal from the base station; and receiving a channel state information-reference signal (CSI-RS) from the base station, and acquiring downlink time and frequency synchronization with the base station on the basis of the CSI-RS.

Abstract: A communication method and system for converging a 5G communication system for supporting higher data rates beyond a 4G system with a technology for Internet of Things (IoT) is disclosed. 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.
