Claim 3:
4. A method performed by a second network node for handling uplink (UL) signals transmitted by a user equipment (UE) for positioning purpose in a wireless communications network that includes the second network node and at least first and third network nodes, the method comprising:
determining that the UE needs to transmit UL signals for positioning purpose;
determining, for the UE, an UL signal switching configuration and an UL signal configuration to transmit UL signal for positioning purpose on one or more carriers on which the UE is not configured to transmit user data;
sending, to one or more of the first network node and the third network node, information about the determined UL signal switching configuration and the determined UL signal configuration;
sending, to the UE, the determined UL signal switching configuration and the determined UL signal configuration; and
sending, to the UE, an UL signal switching order to switch to at least one carrier on which the UE is not configured to transmit user data, to transmit UL signals for positioning purpose.
