Abstract

A method performed by a network node operating as a Master Node (MN) for conditional Primary Secondary Cell Change (CPC) includes sending, to a target candidate secondary node (SN) an SN Addition Request message and receiving, from the target candidate SN, an SN Addition Request Acknowledge message comprising a RRC Reconfiguration message (RRCReconfiguration**) for a target candidate cell. The network node sends, to a wireless device, an RRC Reconfiguration message (RRCReconfiguration), which includes at least one conditional reconfiguration for the CPC. The conditional reconfiguration includes: another RRC Reconfiguration message (RRCReconfiguration*); at least one execution condition for the CPC; and a conditional reconfiguration identity associated with the CPC for the target candidate cell. The RRCReconfiguration* includes the RRCReconfiguration**. The network node receives, from the wireless device, a first reconfiguration complete message (RRCReconfigurationComplete) and a second RRCReconfigurationComplete message (RRCReconfigurationComplete*), which includes another RRCReconfigurationComplete message (RRCReconfigurationComplete**).
