Abstract: Various communication systems may benefit from improved positioning estimation. For example, certain embodiments may benefit from improved radio-based positioning estimation of a target user equipment using an observed time difference of arrival. A method, in certain embodiments, may include receiving at a target user equipment from a network entity a list comprising a plurality of supporting user equipment and a plurality of base stations. The method may also include receiving at the target user equipment supporting positioning reference signals via sidelink transmission from the plurality of supporting user equipment and positioning reference signals from the plurality of base stations. In addition, the method may include taking observed time difference of arrival measurements or determining a position estimate at the target user equipment based on the positioning reference signals and the supporting positioning reference signals.

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.
