    Abstract: A 5th generation (5G) or pre-5G communication system supporting higher data rate after a 4th generation (4G) communication system such as a long-term evolution (LTE) is disclosed. The system includes a scalable frame structure to integrally support various services in a cellular wireless communication system, and provides a transmission/reception method to which the corresponding frame structure is applied, so that the system performance is improved through minimizing of inter-symbol interference between the 5G system and the LTE system or between the 5G systems. The scalable frame structure adjusts a cyclic prefix (CP) length by giving a specific pattern thereto when subcarrier spacing is extended, while maintaining a CP overhead in the same manner based on the frame structure based on a specific subcarrier spacing, thereby maintaining the 2m-times relationship between a symbol length, CP length, slot length, and subframe length.
