Abstract: A method for transmitting a sounding reference signal (SRS) by a by a user equipment (UE) includes: receiving, from a base station, first information on a number of SRS symbols configured for one slot and second information on a number of repetitions of symbols configured for transmission of an SRS; determining whether the number of repetitions is greater than the number of the SRS symbols; when the number of repetitions is greater than the number of the SRS symbols, determining the number of repetitions of the symbols by a value identical to the number of the SRS symbols; and transmitting the SRS based on the determined number of repetitions. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station, or a network.

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.
