Abstract
A method of operating a first device 100 in a wireless communication system is proposed. The method may comprise: obtaining information related to an SL PRS resource; receiving a first PRS at a first time point, based on the SL PRS resource; receiving a second PRS at a second time point, based on the SL PRS resource; receiving, a first distance value between the second device 200 and the third device 300; obtaining a first RSTD value between the second device 200 and the third device 300; and performing the positioning based on the first RSTD value.
Claims15
A method for performing, by a first device, wireless communication, the method comprising:
- obtaining information related to a sidelink (SL) positioning reference signal (PRS) resource, for positioning of the first device;
- receiving a first PRS at a first time point, from a second device included in an SL positioning group for the positioning, based on the SL PRS resource;
- receiving a second PRS at a second time point, from a third device included in the SL positioning group, based on the SL PRS resource;
- receiving, from the second device, a first distance value between the second device and the third device;
- obtaining a first reference signal time difference (RSTD) value between the second device and the third device, based on the first time point, the second time point, and the first distance value;
- and
- performing the positioning based on the first RSTD value,
- wherein the first PRS is transmitted by the second device at a third time point,
- wherein the second PRS is transmitted by the third device at a fourth time point, which is after a time point at which the first PRS is received by the third device by a first time interval, and
- wherein the first distance value is obtained based on the third time point, a fifth time point at which the second PRS is received by the second device, and the first time interval.
