Abstract: Example embodiments of the present disclosure relate to transmission of control information associated with sidelink positioning reference signal. In an example method, a first terminal device in a radio access network comprises at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the first terminal device to: transmit, to a second terminal device in the radio access network, control information associated with a sidelink (SL) positioning reference signal (PRS) during a SL positioning session for positioning of the second terminal device, using a resource for the control information in a Physical Sidelink Feedback Channel (PSFCH) symbol or in at least one symbol dedicated for the control information. In this way, the first terminal device can efficiently transmit control information to the second terminal device with backward compatibility.

Abstract: Systems, methods, apparatuses, and computer program products for non-stationary carrier-phased positioning (CPP). A method may include receiving an indication to transmit a sounding reference signal or a carrier phase positioning measurement. The indication may include at least a phase pre-compensation on the sounding reference signal transmission or a correction of the carrier phase positioning measurement based at least on a Doppler shift. The method may also include performing, at a user equipment, the phase pre-compensation for the sounding reference signal transmission, or the correction of the carrier phase positioning measurement. The method may further include transmitting, by the user equipment, the sounding reference signal with the phase pre-compensation or the carrier phase positioning measurement.
