Avoiding simultaneous conditional handover and conditional primary SCG cell change

Example implementations include a method, apparatus and computer-readable medium of wireless communication at a secondary node (SN), comprising determining to perform conditional primary SCG cell (PSCell) change (CPC) of a user equipment (UE) to one of a set of target primary SCG cells within the SN different from a current primary SCG cell. The implementations further include generating a secondary cell modification message including identification information for the set of target primary SCG cells for the CPC. Additionally, the implementations further include transmitting the secondary cell modification message including the identification information for the set of target primary SCG cells for the CPC to a master node (MN) associated with the UE. Additionally, the implementations further include receiving a response message from the MN indicating a confirmation or a rejection of the secondary cell modification message. Example method, apparatus and computer-readable medium of wireless communication at the MN are included.
