Abstract: Example embodiments of the present disclosure relate to constant transmission. In an example method, a terminal device transmits a reference signal (RS) for positioning at a fixed transmission timing, wherein a RS for positioning configuration is valid in multiple cells. Based on determining that at least one condition for maintaining the fixed transmission timing is not satisfied, the terminal device performs at least one operation to cause the transmission timing of a subsequent RS for positioning to be fixed with or without an update of the transmission timing. In this way, positioning measurement accuracy can be improved, and the signaling overhead between the terminal devices and the network devices, and between network devices can be reduced.
