Abstract: The present disclosure relates to reference signal transmission alignment. In particular, a target device determines whether a reference signal transmission alignment is needed among a set of anchor devices. If the reference signal transmission alignment is needed, an anchor device receives a request for the reference signal transmission alignment. The anchor device determines a transmission time window based on the request and transmits a reference signal as per the transmission time window. In this way, it can mitigate an impact of synchronization timing reference change at the target device in measurement. Consequently, the solution allows for high accuracy measurements and hence enables high accuracy sidelink positioning.
