Abstract: Systems and methods for activation and deactivation of Sidelink (SL) Positioning Reference Signal (PRS) are provided. In some embodiments, a method performed by a UE includes: receiving control signaling for triggering SL PRS, where the control signaling includes: a resource allocation in time and/or frequency domain; a comb and/or repetition factor associated with SL PRS; an identifier for the SL PRS; an offset between receiving the control signal and when the SL PRS will be transmitted or received/measured; and an indicator indicating whether the SL PRS is for transmission or reception/measurement by the UE. In this way, some embodiments enable semi-persistent or aperiodic SL PRSs to be activated/deactivated or triggered on when SL positioning measurements are needed. Hence, these embodiments allow interference caused by SL PRS to other UEs to be reduced. In addition, the proposed solutions also reduce the SL overhead when compared to a periodic SL PRS transmission.

Abstract: The disclosed invention makes use of a wheel speed signal to detect a wheel anomaly such as a loose wheel or a wheel with zero pressure. The wheel speed signal is used as a basis to determine a first and a second detection signal. A further basis for determining the first and second detection signals are a first and second reference signal, respectively. The anomaly of e.g. a loose wheel is detected, according to the teaching of the invention if at least one of the detection signals exceeds a threshold. In particular, the disclosure relates to methods, systems and computer program products to achieve the mentioned objective.
