DEVICES FOR ESTABLISHING MULTIPLE CONNECTIONS

摘要

A method by a User Equipment (UE) is described. The method includes establishing a first radio interface between the UE and a first point on an Evolved Universal Terrestrial Radio Access Network (E-UTRAN). The method also includes establishing a second radio interface between the UE and a second point on the E-UTRAN by using the first radio interface. The method further includes mapping data radio bearers (DRBs) to at least one of the first radio interface and the second radio interface.

1. A method by a primary evolved NodeB (PeNB), comprising:
communicating with a secondary evolved NodeB (SeNB) via a X2 interface for inter-eNB control plane signaling for dual connectivity, wherein the control plane signaling towards a Mobility Management Entity (MME) is performed by means of S1 interface signaling, S1-U interface only terminates in the PeNB and user plane data is transferred from the PeNB to SeNB using the X2 interface.
