(canceled) ### Claim 21 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. ### Claim 22 (depends on 21) The apparatus of claim 21, wherein the first network node comprises a long term evolution base station, and wherein the second network node comprises a next generation radio technology base station. ### Claim 23 (depends on 21) The apparatus of claim 21, wherein the determining that the user equipment is to be dual connected is based on a measurement report from the user equipment. ### Claim 24 (depends on 21) The apparatus of claim 21, wherein the identifying is based on at least one of channel power control status information, quality indicator information and throughput expectations of at least one of the first network node, the second network node, and the user equipment. ### Claim 25 (depends on 21) The apparatus of claim 21, wherein the sent information comprises an indication of identifiers of the at least one supported radio configuration within the capability information. ### Claim 26 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. ### Claim 27 (depends on 26) The apparatus of claim 26, wherein the information from the first network node comprises a tight interworking request by the first network node. ### Claim 28 (depends on 26) The apparatus of claim 26, wherein the information from the first network node comprises an indication of identifiers of the supported at least one radio configuration within the capability information, wherein the choosing is based on the identifiers. ### Claim 29 (depends on 26) The apparatus of claim 26, wherein the first network node comprises a long term evolution base station, and wherein the second network node comprises a next generation radio technology base station. ### Claim 30 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. ### Claim 31 (depends on 30) The method of claim 30, wherein the first network node comprises a long term evolution base station, and wherein the second network node comprises a next generation radio technology base station. ### Claim 32 (depends on 30) The method of claim 30, wherein the determining that the user equipment is to be dual connected is based on a measurement report from the user equipment. ### Claim 33 (depends on 30) The method of claim 30, wherein the identifying is based on at least one of channel power control status information, quality indicator information and throughput expectations of at least one of the first network node, the second network node, and the user equipment. ### Claim 34 (depends on 30) The method of claim 30, wherein the sent information comprises an indication of identifiers of the at least one supported radio configuration within the capability information.
