Method and device for indicating resource reservation information for sl positioning

A method for performing wireless communication by a first device, the method comprising:

• obtaining configuration information related to a sidelink (SL) positioning reference signal (PRS) for a SL-based positioning;
• transmitting, to a second device, through a physical sidelink control channel (PSCCH), first sidelink control information (SCI) for scheduling a physical sidelink shared channel (PSSCH) and second SCI;
• and
• transmitting, to the second device, the second SCI, a SL data, and a first SL PRS, based on a resource related to the PSSCH,
• wherein a priority value of the transmission of the first SL PRS is identical to a priority value of the transmission of the SL data.

A first device adapted to perform wireless communication, the first device comprising:

• at least one transceiver;
• at least one processor;
• and
• at least one memory connected to the at least one processor and storing instructions that, based on being executed, cause the first device to perform operations comprising:
• obtaining configuration information related to a sidelink (SL) positioning reference signal (PRS) for a SL-based positioning;
• transmitting, to a second device, through a physical sidelink control channel (PSCCH), first sidelink control information (SCI) for scheduling a physical sidelink shared channel (PSSCH) and second SCI;
• and
• transmitting, to the second device, the second SCI, a SL data, and a first SL PRS, based on a resource related to the PSSCH,
• wherein a priority value of the transmission of the first SL PRS is identical to a priority value of the transmission of the SL data.

A processing device adapted to control a first device to perform wireless communication, the processing device comprising:

• at least one processor;
• and
• at least one memory connected to the at least one processor and storing instructions that, based on being executed, cause the at least one processor to perform operations comprising:
• obtaining configuration information related to a sidelink (SL) positioning reference signal (PRS) for a SL-based positioning;
• transmitting, to a second device, through a physical sidelink control channel (PSCCH), first sidelink control information (SCI) for scheduling a physical sidelink shared channel (PSSCH) and second SCI;
• and
• transmitting, to the second device, the second SCI, a SL data, and a first SL PRS, based on a resource related to the PSSCH,
• wherein a priority value of the transmission of the first SL PRS is identical to a priority value of the transmission of the SL data.
