Abstract

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