SYSTEMS AND METHODS FOR DATA OFFLOAD IN WIRELESS NETWORKS

摘要

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.

主权项

1. A method of a user equipment (UE), comprising:
transmitting an uplink radio resource control (RRC) messages to a first base station, wherein the uplink RRC message is associated with a second base station, and the UE communicates with a plurality of base stations concurrently; and receiving a downlink RRC message from the second base station.
