Abstract:
Systems, methods, and apparatuses for data and/or control offloading and handover in heterogeneous wireless communication networks are provided. Data and/or control packets can be offloaded to a coordinating base station while a user equipment (UE) remains associated with its serving cell. The packets are still transferred between the serving base station and the core network, and the offloaded data and/or control packets are forwarded from the serving base station to the coordinating base station for transmission to the UE. Furthermore, during a handover process, the serving base station and coordinating base station may independently schedule and send a handover command to the UE to reduce the radio link failure rate.
