More particularly, a method for transmitting, by a terminal, a sounding reference signal (SRS) for beam management in a wireless communication system may comprise the steps of: receiving SRS configuration information configured in units of transmission units for uplink transmission; and transmitting the SRS through a specific transmission unit determined on the basis of the SRS configuration information. The SRS configuration information may include configuration information relating to a reception unit for downlink reception associated with the specific transmission unit. ## Claims ### Claim 1 A method performed by a user equipment in a wireless communication system, the method comprising: receiving, from a base station, sounding reference signal (SRS) configuration information that identifies at least one transmission unit of a plurality of transmission units of the user equipment to be used to transmit a SRS for beam management, wherein the plurality of transmission units are separated by a distance such that each of the plurality of transmission units are configurable by transmission unit specific SRS configuration parameters; and based on the SRS configuration information, transmitting the SRS to the base station through the at least one transmission unit, wherein the SRS configuration information also identifies a reception unit of a plurality of reception units of the user equipment to be used for downlink reception, wherein the plurality of reception units are respectively associated with the plurality of transmission units, and wherein the reception unit is associated with the at least one transmission unit. ### Claim 2 (depends on 1) The method of claim 1, wherein a plurality of SRS resource sets within the SRS configuration information is configured for the plurality of transmission units of the user equipment, respectively, and wherein identification information of a downlink reference signal is configured for each of the plurality of SRS resource sets. ### Claim 3 (depends on 2) The method of claim 2, wherein at least one beam for the transmission of the SRS is determined based on the identification information of the downlink reference signal. ### Claim 4 (depends on 1) The method of claim 1, wherein the SRS configuration information further identifies at least one beam of the at least one transmission unit to be used to transmit the SRS, and wherein the at least one beam is identified by at least one of a beam identifier, an SRS resource identifier, a channel state information-reference signal (CSI-RS) resource identifier or a synchronization signal block (SSB) identifier. ### Claim 5 (depends on 4) The method of claim 4, wherein when the at least one beam identified by the SRS configuration information comprises two beams, the two beams are a first beam and a last beam configured for the transmission of the SRS, respectively. ### Claim 6 (depends on 4) The method of claim 4, wherein when the at least one beam identified by the SRS configuration information comprises multiple beams associated with multiple SRS resources, different beams of the multiple beams are applied to contiguous SRS resources among the multiple SRS resources. ### Claim 7 (depends on 6) The method of claim 6, wherein the multiple SRS resources are included in one SRS resource set configured by the SRS configuration information for the at least one transmission unit. ### Claim 8 A user equipment in a wireless communication system, the user equipment comprising: a radio frequency (RF) module including a transceiver; at least one processor; and at least one computer memory operatively coupled to the at least one processor and configured to store instructions performing operations when executed by the at least one processor, wherein the operations comprises: receiving, from a base station, sounding reference signal (SRS) configuration information that identifies at least one transmission unit of a plurality of transmission units of the user equipment to be used to transmit a SRS for beam management, wherein the plurality of transmission units are separated by a distance such that each of the plurality of transmission units are configurable by transmission unit specific SRS configuration parameters, and based on the SRS configuration information, transmitting the SRS to the base station through the at least one transmission unit, wherein the SRS configuration information also identifies a reception unit of a plurality of reception units of the user equipment to be used for downlink reception, wherein the plurality of reception units are respectively associated with the plurality of transmission units, and wherein the reception unit is associated with the at least one transmission unit. ### Claim 9 (depends on 8) The user equipment of claim 8, wherein a plurality of SRS resource sets within the SRS configuration information is configured for the plurality of transmission units of the user equipment, respectively, and wherein identification information of a downlink reference signal is configured for each of the plurality of SRS resource sets. ### Claim 10 (depends on 9) The user equipment of claim 9, wherein at least one beam for the transmission of the SRS is determined based on the identification information of the downlink reference signal. ### Claim 11 (depends on 8) The user equipment of claim 8, wherein the SRS configuration information further identifies at least one beam of the at least one transmission unit to be used to transmit the SRS, and wherein the at least one beam is identified by at least one of a beam identifier, an SRS resource identifier, a channel state information-reference signal (CSI-RS) resource identifier or a synchronization signal block (SSB) identifier. ### Claim 12 (depends on 11) The user equipment of claim 11, wherein when the at least one beam identified by the SRS configuration information comprises two beams, the two beams are a first beam and a last beam configured for the transmission of the SRS, respectively. ### Claim 13 (depends on 11) The user equipment of claim 11, wherein when the at least one beam identified by the SRS configuration information comprises multiple beams associated with multiple SRS resources, different beams of the multiple beams are applied to contiguous SRS resources among the multiple SRS resources, and wherein the multiple SRS resources are included in one SRS resource set configured by the SRS configuration information for the at least one transmission unit.
