A master node (MN) may receive a secondary node (SN) change required message from a source SN. The MN may send an indication of a maximum number of candidate PSCells that can be configured by a target SN, in an SN addition request message, to the target SN. The MN may receive, from the target SN, at least one candidate PSCell configuration, in an SN addition request acknowledge message, in response to the SN addition request message. The MN may send a RRC message to a wireless communication device, the RRC message including the at least one candidate PSCell configuration and one or more associated CPAC execution conditions.
