Abstract

Disclosed are a method and device for performing uplink transmission and reception in a communication system. The method performed by a terminal in a wireless communication system according to an embodiment disclosed herein comprises the steps of: receiving information about the configuration of an SRS resource set; receiving DCI including a first PTRS-DMRS port association field and a second PTRS-DMRS port association field; and transmitting a PTRS on the basis of at least one of the first PTRS-DMRS port association field or the second PTRS-DMRS port association field. Here, on the basis that three PTRS ports are configured for the terminal, the first PTRS-DMRS port association field may indicate information about one DMRS port associated with one PTRS port and the second PTRS-DMRS port association field may indicate information about two DMRS ports associated with two PTRS ports.
