Method for transmitting and receiving positioning reference signal and apparatus therefor

A method performed by a transmission reception point (TRP) in a wireless communication system, the method comprising:

• transmitting configuration information related to positioning reference signal (PRS) resource sets each including one or more PRS resources;
• and
• performing PRS transmission based on the configuration information,
• wherein the configuration information includes one or more PRS resource identifiers (IDs) of the one or more PRS resources in each PRS resource set, and transmission periodicity and slot offset information related to each PRS resource set,
• wherein, for a single instance of a first PRS resource set, each PRS resource in the first PRS resource set is repeated based on repetition information included in the configuration information,
• wherein a time gap is configured between repetitions of a PRS resource with a same PRS ID within the single instance of the first PRS resource set, and
• wherein each PRS resource in the first PRS resource set is associated with each PRS beam of the TRP.

A device for wireless communication, the device comprising:

• a memory configured store instructions;
• and
• a processor configured to perform operations by executing the instructions, the operations comprising:
• receiving configuration information related to positioning reference signal (PRS) resource sets each including one or more PRS resources;
• and
• performing PRS reception based on the configuration information,
• wherein the configuration information includes one or more PRS resource identifiers (IDs) of the one or more PRS resources in each PRS resource set, and transmission periodicity and slot offset information related to each PRS resource set,
• wherein, for a single instance of a first PRS resource set, each PRS resource in the first PRS resource set is repeated based on repetition information included in the configuration information,
• wherein a time gap is configured between repetitions of a PRS resource with a same PRS ID within the single instance of the first PRS resource set, and
• wherein each PRS resource in the first PRS resource set is associated with each PRS beam of a transmission reception point (TRP).
