UNIFYING SPLIT BEARERS IN LTE INTERWORKING

There is provided an apparatus for communications. The apparatus comprising a memory interface to store an encapsulated secondary cell group configuration; andcircuitry for a first base station. The circuitry to: transmit a message to a second base station comprising a request to add the second base station as a secondary node, SN; receive a request acknowledgement message from the second base station, comprising an encapsulated secondary cell group, SCG, configuration; generate and transmit a radio resource control, RRC configuration message to a user equipment, UE, the RRC configuration message comprising a master cell group, MCG, configuration and the encapsulated SCG configuration, the MCG configuration and the encapsulated SCG configuration each containing radio resource configuration information to respectively configure master node, MN or SN protocol stacks; and establish, based on the configured MN or SN protocol stacks, communication between the UE, the first base station, and the second base station, where data to or from the UE is split and communicated to or from the UE via either the first base station or the second base station.
