1. A method performed by a user equipment (UE) for transmitting uplink (UL) signals for positioning purpose in a wireless communications network that includes at least first and second network nodes, the method comprising:
receiving, from the second network node, an UL signal switching configuration and an UL signal configuration to transmit UL signals for positioning purpose on one or more carriers on which the UE is not configured to transmit user data;
receiving from the second network node an UL signal switching order;
based on the UL signal switching order, switching to at least one carrier on which the UE does not transmit user data, to transmit the UL signals for positioning purpose; and
switching back to a carrier on which the UE is configured to transmit user data.
