    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.

    Abstract: Embodiments of the present disclosure relate to beam selection during downlink positioning. According to embodiments of the present disclosure, the terminal devices are grouped based on their characteristics and the anchor terminal device in the group determines the best transmitting beam of the neighbor network device. The non-anchor terminal device uses the assistance information of the best transmitting beam determined by the anchor terminal device. In this way, cost for the terminal device to receive and measure the PRS during downlink positioning has been reduced.

    Abstract: Embodiments of the present disclosure relate to methods, devices, apparatuses and computer readable storage media for multi-cell positioning. In example embodiments, a method is provided. The method includes transmitting, from a first network device, a first reference signal to a terminal device served by a second network device. The method further includes receiving a second reference signal from the second network device. The method further includes determining a first time difference between a time at which the first RS is transmitted and a time at which the second reference signal is received. In addition, the method includes transmitting information on the first time difference to a location server. As such, the location server can determine positioning information about the terminal device.
