Abstract: A method for a terminal transmitting a signal according to a resource allocation priority may comprise the steps of: when a sounding reference signal (SRS) symbol and a physical uplink control channel (PUCCH) symbol are configured so as to overlap, transmitting an SRS in a non-overlapping symbol; and dropping the transmission of the SRS in the overlapping symbol. The present invention can improve communication performance by being able to carry out transmission according to a resource allocation priority rule, when the SRS and PUCCH resource areas overlap.
