Methods and apparatus for dual connectivity operation in a wireless communication network

Abstract:

Dual-connectivity for the User Equipment (UE) in a cellular network is performed by monitoring a plurality of cells. During dual-connectivity, the UE may be simultaneously connected to one serving cell for the Control Plane (C-plane) and to another serving cell, controlled by a different eNodeB, for the User Plane (U-plane). In another embodiment, the dual-connected UE monitors a Physical Downlink Control Channel (PDCCH) from the first eNB and monitors an EPDCCH from the second eNB.
