Coordinating MRO analysis for PSCell change failure

An apparatus, comprising:

• at least one processor;
• at least one memory storing instructions, wherein the instructions, when executed by the at least one processor, cause the apparatus to perform, at least:
• by a secondary node, of a secondary cell group, configured for wireless communication with a user equipment and for communication with a master node, receiving from the master node a message corresponding to a secondary cell group failure;
• determining whether or not the secondary node is responsible for the secondary cell group failure;
• and
• indicating to the master node by the secondary node whether or not the secondary node is responsible for the secondary cell group failure.

A method, comprising:

• by a master node configured for wireless communication with a user equipment and for communication with one or more secondary nodes, after receiving a first indication from the user equipment that a secondary cell group failure has occurred, transmitting to a last serving secondary node a message corresponding to the secondary cell group failure;
• receiving, by the master node from the last serving secondary node, information indicating whether or not the last serving secondary node is responsible for the secondary cell group failure;
• based on the received information, determining by the master node which node of at least the master node or the last serving secondary node or another secondary node is responsible for the secondary cell group failure;
• and
• performing by the master node an analysis for mobility robustness for the secondary cell group failure when it is determined that the master node was responsible for the secondary cell group failure.

• determining whether or not the secondary node is responsible for the secondary cell group failure;
• and
• indicating to the master node by the secondary node whether or not the secondary node is responsible for the secondary cell group failure.
