Abstract

A method (800) performed by a T-SN for cancelling a conditional PSCell, change (CPC). The method includes the T-SN receiving (s802) a request for a CPC configuration for a UE, wherein the request was transmitted by a first network node (NN), and the UE is connected to the first NN and is also connected to a second NN. The method also includes the T-SM transmitting (s804) to the first NN a response to the request, the response including the CPC configuration for the UE. The method further includes, after transmitting the response, the T-SN transmitting (s806) to the first NN a cancellation indication indicating that the CPC configuration for the UE is cancelled.
