Title:
RETRANSMISSION OF SIDELINK POSITIONING REFERENCE SIGNAL
Document Type and Number:
WIPO Patent Application WO/2022/126496
Kind Code:
A1
Abstract:
Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of retransmission of sidelink positioning reference signal (PRS). The method comprises transmitting, to a second device, a first sidelink reference signal associated with a positioning or ranging procedure of the first device; and receiving, from the second device, a second sidelink reference signal associated with the positioning or ranging procedure, the second sidelink reference signal comprising information indicating whether the first sidelink reference signal needs to be retransmitted. In this way, the retransmission of the sidelink PRS can be triggered without extra resource consumption and a fast RTT estimation for sidelink ranging and positioning can be achieved.
