    摘要: A communication method and system for converging a fifth generation (5G) communication system for supporting higher data rates beyond a fourth generation (4G) system with a technology for internet of things (IoT) includes intelligent services based on the 5G communication technology and the IoT-related technology. A method by a terminal for transmitting uplink data in a wireless communication system comprises receiving downlink control information for scheduling of uplink transmission in a cell from a base station and transmitting the uplink data to the base station on the supplementary uplink if the indicator indicates the scheduling of the uplink transmission is associated with the supplementary uplink in the cell. The downlink control information includes an indicator indicating whether the scheduling of the uplink transmission is associated with a supplementary uplink in the cell.

    摘要: The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data rate beyond a 4G communication system such as LTE. According to an embodiment of the present invention, a method for transmitting a synchronization signal by a base station in a filter bank multi carrier (FBMC) system and a base station using the same may be provided, the method comprising the steps of: generating a frequency-domain quadrature amplitude modulation (QAM) symbol sequence having a length of k for a synchronization signal; mapping the QAM symbol sequence to a sub-carrier of a filter bank on the basis of the correlation characteristic of the synchronization signal; generating a quadrature amplitude modulation-filter bank multicarrier (QAM-FBMC) symbol including the synchronization signal on the basis of the mapping, and transmitting the generated QAM-FBMC symbol. In addition, a terminal communicating with the base station and an operation method for the terminal may be provided.
