    摘要： A method and an apparatus for detecting inter-cell interference in a mobile communication system are provided. A base station receives a reference signal (RS) from a terminal, generate one or more interference candidate RSs, calculate a cross correlation of the one or more interference candidate RSs and the received RS, estimate at least one of a size of a Resource Block (RB) an offset of the RB, a group index (U), and a cyclic shift (CS) by using a preset number of interference candidate RSs in an order of the large cross correlation. The base station further removes an interference signal or performs a direct reduction by using at least one of the estimated RB size, the RB offset, the timing offset, and the group index (U). According to the present disclosure, it is beneficial to mitigate or cancel inter-cell interference problem on an uplink transmission without any assistance of neighbor base stations and/or adjacent cells in a wireless communication system.

    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.
