Inter Secondary Node Conditional PSCell Change

A system, comprising:

• a user equipment, operable to transceive communications with one or more communication nodes, wherein the user equipment supports conditional cell change operations and receives a conditional reconfiguration message;
• a master node operable to transceive communications with the user equipment;
• a source secondary node operable to transceive communications with the master node;
• and
• a target secondary node operable to transceive communications with the master node and the source secondary node, wherein the source secondary node is operable to communicate a secondary node/secondary 5G base station change required message that includes one or more measurement identifications corresponding to a prepared target primary secondary cell.

A method for configuring a conditional cell change operation at a user equipment for a master node, a source secondary node, and a target secondary node, where the master node is one of a first 5G base station, a first enhanced node B, a first enhanced 5G base station, or a first next generation enhanced node B, the source secondary node is one of a second 5G base station, a second enhanced node B, a second enhanced 5G base station, or a second next generation enhanced node B, and the target secondary node is one of a third 5G base station, a third enhanced node B, a third enhanced 5G base station, or a third next generation enhanced node B, the method comprising:

• including one or more of a set of measurement identifications or target primary secondary cell to be prepared with the target secondary node in a secondary node/secondary 5G base station change required message sent from the source secondary node;
• communicating an addition request message and an addition request acknowledge message as response to receiving the secondary node/secondary 5G base station change required message sent from the source secondary node;
• generating a conditional reconfiguration message in response to one or more of the addition request acknowledge message, the measurement identifications, a default measurement identification, or the prepared target primary secondary cell configurations;
• and
• transmitting the conditional reconfiguration message to the user equipment.
