Abstract

A method for re-establishing a connection by a user equipment (UE) is described. The method includes establishing a first connection between the UE and an Evolved Universal Terrestrial Radio Access Network (E-UTRAN). The method also includes establishing a second connection between the UE and the E-UTRAN. The method also includes informing the E-UTRAN of a failure of the second connection when a failure of the second connection is detected.

Claims (10)

1. A method for dual connectivity by an evolved Node B (eNB), comprising:

establishing, by the eNB, a first set of cells and a second set of cells for a user equipment (UE),

receiving, by the eNB using the first set of cells, information about a failure of the second set of cells, wherein the failure of the second set of cells is detected by the UE, the failure of the second set of cells includes a radio link failure of the second set of cells and the radio link failure is detected based on a certain amount of consecutive out-of-sync indications of a certain cell from a physical layer of the UE.

2. The method of claim 1 , wherein the information comprises a cause of the failure.

3. An evolved Node B (eNB) for dual connectivity, comprising:

a processor; and

memory stored in electronic communication with the processor, wherein instructions stored in the memory are executable to:

establish, by the eNB, a first set of cells and a second set of cells for a user equipment (UE),

receive, by the eNB, by using the first set of cells, information about a failure of the second set of cells, wherein the failure of the second set of cells is detected by the UE, the failure of the second set of cells includes a radio link failure of the second set of cells and the radio link failure is detected based on a certain amount of consecutive out-of-sync indications of a certain cell from a physical layer of the UE.

4. The eNB of claim 3 , wherein the information comprises a cause of the failure.
