Systems, methods, and apparatuses for radio resource control (RRC) signaling in wireless communication networks with data offload are provided. The radio configuration messages from a small cell to a dual connection UE may be sent by an overlay macro E-UTRAN node-B (eNB). The small cell may send the RRC messages to the macro-eNB first via a backhaul link, and the macro-eNB then transmits the messages to the UE. In some implementations, the radio configuration messages from a small cell to a dual connection UE may be sent directly from the small cell. In some other implementations, some of the RRC messages may be sent selectively to/from either the macro-cell or the small cell, or to/from both the macro-cell and the small cell. The type of RRC messages sent over the small cell and/or the macro-cell may be preconfigured or predetermined. |
