Method for transmitting and receiving sounding reference signal in wireless communication system, and apparatus therefor

1. A method for transmitting, by a user equipment (UE), a sounding reference signal (SRS) in a wireless communication system, the method comprising:

transmitting UE capability information associated with a sound reference signal (SRS) for downlink channel state information (DL CSI) acquisition;

receiving configuration information related to transmission of the SRS; and

transmitting the SRS,

wherein the UE capability information is related to a plurality of panels,

wherein at least one of SRS resource sets is configured for each panel among the plurality of panels based on the UE capability information, and

wherein the SRS is transmitted based on at least one of the plurality of panels,

wherein based on the UE capability information including information representing simultaneous transmission of the SRS resource sets of the respective panels, the SRS resource sets for different panels are configured in the same slot, and at least one SRS resource which belongs to the SRS resource sets for the different panels is configured in the same symbol.

2. The method of claim 1 , wherein the UE capability information further includes information on at least one of the number of plurality of panels, the number of antennas for each panel, or a panel switching delay.

3. The method of claim 2 , wherein the number of plurality of panels includes at least one of the number of transmission (Tx) panels or the number of reception (Rx) panels.

4. The method of claim 2 , wherein the configuration information includes information on the at least one of the SRS resource sets for the plurality of panels, the at least one SRS resource which belongs to each SRS resource set among the SRS resource sets, or candidate locations of the at least one SRS resource.

5. The method of claim 1 , wherein the SRS is transmitted in at least one symbol based on a specific location among the candidate locations of the SRS resource.

6. The method of claim 5 , further comprising:

receiving a message including information representing the specific location.

7. The method of claim 6 , wherein the message is based on a Medium Access Control-Control Element (MAC-CE) or Downlink Control Information (DCI).

8. A UE for transmitting a sounding reference signal (SRS) in a wireless communication system, the UE comprising:

one or more transceivers;

one or more processors; and

one or more memories operably connectable to the one or more processors, and storing instructions of performing operations when the transmission of the SRS is executed by the one or more processors,

wherein the operations include

transmitting UE capability information associated with a sound reference signal (SRS) for downlink channel state information (DL CSI) acquisition,

receiving configuration information related to transmission of the SRS, and transmitting the SRS, and

transmitting the SRS,

wherein the UE capability information is related to the plurality of panels,

wherein at least one of the SRS resource sets is configured for each panel among the plurality of panels based on the UE capability information, and

wherein the SRS is transmitted based on at least one of the plurality of panels,

wherein based on the UE capability information including information representing simultaneous transmission of the SRS resource sets of the respective panels, the SRS resource sets for different panels are configured in the same slot, and at least one SRS resource which belongs to the SRS resource sets for the different panels is configured in the same symbol.

9. A method for receiving, by a base station (BS), a sounding reference signal (SRS) in a wireless communication system, the method comprising:

receiving UE capability information associated with a sound reference signal (SRS) for downlink channel state information (DL CSI) acquisition;

transmitting configuration information related to transmission of the SRS; and

receiving the SRS,

wherein the UE capability information is related to the plurality of panels,

wherein at least one of the SRS resource sets is configured for each panel among the plurality of panels based on the UE capability information, and

wherein the SRS is received based on at least one of the plurality of panels,

wherein based on the UE capability information including information representing simultaneous transmission of the SRS resource sets of the respective panels, the SRS resource sets for different panels are configured in the same slot, and at least one SRS resource which belongs to the SRS resource sets for the different panels is configured in the same symbol.
