Abstract

According to embodiments of the present disclosure, a PRS transmission timing scheme for sidelink assisted positioning is proposed. According to embodiments of the present disclosure, the supporting terminal device measures a receiving-transmitting (Rx-Tx) time difference between receiving the downlink PRS (DL) and transmitting the sidelink (SL) PRS. The supporting terminal device transmits an indication of the RX-TX time difference to the location management device in order to reduce the impact of low synchronization issue on positioning performance as well as the use of wideband PRS for higher measurement accuracy. In this way, the positioning performance of sidelink assisted positioning has been improved.
