Abstract: A device of a base station may comprise memory storing instructions; a transceiver; and a processor. The instructions, when executed by the processor, may cause the device to: receive, uplink signals within symbols of a first slot; obtain an interference strength of a symbol that has an index usable for transmission of a sounding reference signal (SRS) on a neighbor cell from among the symbols of the first slot; determine, as time resources for uplink data to be transmitted from a user equipment (UE) within a second slot, at least one symbol respectively having at least another index distinct from the index from among symbols of the second slot; and transmit, to the UE, downlink control information indicating the at least one symbol from among the symbols of the second slot as the time resources for the uplink data to be transmitted within the second slot.

Abstract: 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.
