Method for controlling transmission power of sounding reference signal (srs) by terminal in wireless communication system, and device therefor

A device for wireless communication, the device comprising:

• at least one processor;
• and
• at least one memory operably connected to the at least one processor and configured to store instructions that, when executed, cause the at least one processor to perform operations comprising:
• receiving, from a serving cell, sounding reference signal (SRS) configuration information;
• and
• transmitting an SRS with an SRS transmission power determined by the device,
• wherein the SRS configuration information includes a downlink reference signal (DL RS) resource information, and the DL RS resource information includes information regarding a DL RS resource of a non-serving cell,
• wherein the SRS transmission is related to a positioning, and
• wherein, based on that the device is not able to accurately measure a path loss reference RS measurement on the DL RS resource of the non-serving cell, the at least one processor performs a DL path loss measurement for the serving cell.

A method of receiving a signal from a user equipment (UE) by at least one base station (BS) in a wireless communication system, the method comprising:

• transmitting, to the UE through a serving cell, sounding reference signal (SRS) configuration information;
• and
• receiving an SRS with an SRS transmission power determined by the UE,
• wherein the SRS configuration information includes a downlink reference signal (DL RS) resource information, and the DL RS resource information includes information regarding a DL RS resource of a non-serving cell,
• wherein the SRS reception is related to a UE positioning, and
• wherein, based on a path loss reference RS measurement on the DL RS resource of the non-serving cell cannot be accurately measured in the UE, a DL path loss measurement for the serving cell is performed by the UE.

A device configured with at least one cell for wireless communication, the device comprising:

• at least one processor;
• and
• at least one memory operably connected to the at least one processor and configured to store instructions that, when executed, cause the at least one processor to perform operations comprising:
• transmitting, through a first cell which is a serving cell of the UE, sounding reference signal (SRS) configuration information;
• and
• receiving an SRS with an SRS transmission power determined by the UE,
• wherein the SRS configuration information includes a downlink reference signal (DL RS) resource information, and the DL RS resource information includes information regarding a DL RS resource of a non-serving cell,
• wherein the SRS reception is related to a UE positioning, and
• wherein, based on that a path loss reference RS measurement on the DL RS resource of the non-serving cell cannot be accurately measured in the UE, a DL path loss measurement for the serving cell is performed by the UE.
