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

A user equipment (UE) configured to operate in a wireless communication system, the UE comprising:

• a radio frequency (RF) unit;
• at least one processor;
• and
• at least one computer memory operably connected to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
• receiving, from a base station (BS), configuration information for at least one SRS resource set, wherein each of the at least one SRS resource set includes one or more SRS resources;
• and
• transmitting, to the BS, an SRS based on each SRS resource of the at least one SRS resource set,
• wherein based on i) an SRS resource set among the at least one SRS resource set being configured to be used for antenna switching and ii) SRS resources of the SRS resource set being configured in a same slot, a guard period is configured in-between the SRS resources of the SRS resource set,
• wherein based on i) the SRS resource set being configured to be used for the antenna switching and ii) the guard period being configured and iii) the guard period overlapping with at least one physical uplink control channel (PUCCH) symbol which is configured for a PUCCH:
• during the guard period, the UE uses a priority rule between the PUCCH and the guard period which is same as a priority rule between the PUCCH and the SRS.

A method performed by a base station (BS) operating in a wireless communication system, the method comprising:

• transmitting, to a user equipment (UE), configuration information for at least one SRS resource set, wherein each of the at least one SRS resource set includes one or more SRS resources;
• and
• receiving, from the UE, an SRS based on each SRS resource of the at least one SRS resource set,
• wherein based on i) an SRS resource set among the at least one SRS resource set being configured to be used for antenna switching and ii) SRS resources of the SRS resource set being configured in a same slot, a guard period is configured in-between the SRS resources of the ofthe SRS resource set,
• wherein based on i) the SRS resource set being configured to be used for the antenna switching and ii) the guard period being configured and iii) the guard period overlapping with at least one physical uplink control channel (PUCCH) symbol which is configured for a PUCCH:
• during the guard period, a priority rule between the PUCCH and the guard period which is same as a priority rule between the PUCCH and the SRS is used by the UE.
