Performance indicator for interworking radio access technologies

A method comprising:

• determining that a user equipment (UE) can support operation on a given radio band combination comprising a first radio band operating with a first radio access technology (RAT) and a second radio band operating with a second RAT;
• using a performance capability of the UE to obtain at least a second configuration for the second radio band operating with the second RAT;
• and
• configuring the UE with an interworking configuration, the interworking configuration comprising a first configuration to operate on the first band with the first RAT and the second configuration to operate on the second band with the second RAT.

A computer readable memory storing computer program instructions that, when executed by one or more processors, cause a host device to perform actions comprising:

• determining that a user equipment (UE) can support operation on a given radio band combination comprising a first radio band operating with a first radio access technology (RAT) and a second radio band operating with a second RAT;
• using a performance capability of the UE to obtain at least a second configuration for the second radio band operating with the second RAT;
• and
• configuring the UE with an interworking configuration, the interworking configuration comprising a first configuration to operate on the first band with the first RAT and the second configuration to operate on the second band with the second RAT.

An apparatus comprising:

• at least one computer readable memory storing computer program instructions, and
• at least one processor;
• wherein the computer readable memory with the computer program instructions is configured, with the at least one processor, to cause the apparatus at least to:
• determine that a user equipment (UE) can support operation on a given radio band combination comprising a first radio band operating with a first radio access technology (RAT) and a second radio band operating with a second RAT;
• use a performance capability of the UE to obtain at least a second configuration for the second radio band operating with the second RAT;
• and
• configure the UE with an interworking configuration, the interworking configuration comprising a first configuration to operate on the first band with the first RAT and the second configuration to operate on the second band with the second RAT.
