1. An operation method of a terminal in a communication system, the operation method comprising:
receiving from abase station first slot format indicator (SFI) information indicating n flexible symbol(s);
receiving from the base station an SRS configuration message configuring to transmit a sounding reference signal (SRS) to the base station;
receiving from the base station second SFI information re-indicating m symbol(s) among the n flexible symbol(s) as uplink symbol(s); and
transmitting the SRS to the base station through the m symbol(s) re-indicated as UL symbols among the n flexible symbol(s) indicated as flexible symbol(s),
wherein each of n and m is a natural number, k symbols among symbols constituting a slot configured based on the first SFI information and the second SFI information are configured for transmission of the SRS, the SRS is transmitted through the m symbol(s) re-indicated as the UL symbol(s) among the k symbols, the SRS is not transmitted in the flexible symbol among the k symbols, and k is an integer equal to or greater than 2.
