Inter-rat configuration coordination

An apparatus comprising:

• at least one processor;
• and
• at least one memory including computer program code, where the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to at least:
• determine with a first network node of a user equipment that a user equipment is to be dual connected to the first network node and a second network node;
• identify at least one radio configuration supported by the first network node from communication capability information of the user equipment;
• send information to the second network node, the information comprising the capability information and the at least one radio configuration supported by the first network node;
• and
• in response to the sending, receive from the second network node an indication of a chosen at least one radio configuration of the at least one supported radio configuration for use in the dual connection.

An apparatus, comprising:

• at least one processor;
• and
• at least one memory including computer program code, where the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to at least:
• receive with a second network node from a first network node of a communication network information comprising capability information and at least one radio configuration supported by the first network node for dual connectivity with a user equipment;
• choose by the second network node one or more radio configurations of the at least one radio configuration for the dual connectivity, wherein the chosen one or more radio configurations is based on configurations of the at least one radio configuration that are also supported by the second network node;
• and
• send the chosen one or more radio configurations towards the first network node for use in the dual connectivity.

A method comprising:

• determining by a first network node of a user equipment that a user equipment is to be dual connected to the first network node and a second network node;
• identify at least one radio configuration supported by the first network node from communication capability information of the user equipment;
• sending information to the second network node, the information comprising the capability information and the at least one radio configuration supported by the first network node;
• and
• in response to the sending, receiving from the second network node an indication of a chosen at least one radio configuration of the at least one supported radio configuration for use in the dual connection.
