1. A method performed by a User Equipment (UE) for handling a Secondary Cell Group (SCG) configuration in a wireless communications network, the method comprising:
receiving from a network node, while the UE is in RRC_CONNECTED state, a Radio Resource Control (RRC) reconfiguration message including a list of conditional SCG configurations comprising trigger conditions based on signal quality measurements to trigger application of a SCG configuration;
upon reception of said RRC reconfiguration message while the UE is in RRC_CONNECTED state, initiating monitoring of the trigger conditions of cells associated with the SCG configurations; and,
when the trigger condition for a cell is fulfilled according to the received conditional SCG configurations, applying the SCG configuration associated to the cell fulfilling the trigger condition.
