Abstract: Disclosed are a method and an apparatus for uplink transmission in a communication system. An operation method of a terminal includes: receiving, from a base station, first SFI information indicating n flexible symbol(s); receiving, from the base station, second SFI information re-indicating m symbol(s) of the n flexible symbol(s) as uplink (UL) symbol(s); and transmitting an SRS to the base station through the m symbol(s) re-indicated as a UL symbol among the n flexible symbol(s) indicated as a flexible symbol. Therefore, performance of the communication system can be improved.

Abstract: A method for indicating preemption in a communication system is disclosed. A method for operating a terminal comprises the steps of: receiving, from a base station, information indicating a first resource area, to which a preemption-capable resource belongs, for transmission of first data; receiving resource allocation information of second data from the base station; performing a monitoring operation for detecting a PI indicating a preempted resource for transmission of the first data in the first resource area, when the first resource area overlaps with a second resource area indicated by the resource allocation information; and performing decoding on the basis of the detected PI. Therefore, the performance of the communication system may be improved.

Abstract: Feedback methods for repetitive uplink transmissions in a communication system are disclosed. An operation method of a terminal may comprise receiving DL data #1 from a base station through a DL data channel #1; receiving DL data #2 from the base station through a DL data channel #2; and when each of a UL control channel #1 on which an HARQ response #1 for the DL data #1 is to be transmitted and a UL control channel #2 on which an HARQ response #2 for the DL data #2 is to be transmitted overlaps with a UL data channel assigned by the base station, transmitting the HARQ response #1 and the HARQ response #2 to the base station through the UL data channel. Therefore, the performance of the communication system can be improved.
