AI Technical Summary

Technical Problem

In direct link communication scenarios, the positioning or ranging of terminal devices requires sending and/or receiving direct link positioning reference signals (SL PRS), but existing technologies have failed to effectively solve the problem of how terminal devices can flexibly control the transmission power of SL PRS.

Method used

By determining the power configuration information corresponding to SL PRS, including path loss compensation factor, target received power and path loss reference signal, the transmission power of the terminal equipment is calculated, and SL PRS is transmitted in broadcast, multicast, unicast or multicast mode, and the transmission power is determined according to the configuration information or pre-configuration information of the network equipment.

Benefits of technology

It enables flexible control of SL PRS transmission power, improves the reliability of signal transmission, avoids problems of excessive or insufficient power, and enhances the accuracy of positioning and ranging.

Abstract

This disclosure relates to a method, apparatus, and storage medium for transmitting a positioning reference signal. The method includes: a first terminal device determining power configuration information corresponding to a direct link positioning reference signal (SL PRS), and determining a first transmission power corresponding to the SL PRS based on the power configuration information. This allows for flexible control of the first transmission power of the SL PRS based on the power configuration information.
