Systems and methods for re-establishing a connection
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.
1. A method for dual connectivity by a user equipment (UE), comprising:
establishing, by the UE, a first set of cells and a second set of cells for the UE, informing, by the UE using the first set of cells, an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) of a failure of the second set of cells when a failure of the second set of cells is detected by the UE, wherein 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 informing the E-UTRAN of the failure of the second set of cells further comprises indicating a cause of the failure.
3. A user equipment (UE) for dual connectivity, comprising:
a processor; and
memory in electronic communication with the processor, wherein instructions stored in the memory are executable to:
establish, by the UE, a first set of cells and a second set of cells for the UE,
inform, by the UE, by using the first set of cells, an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) of a failure of the second set of cells when a failure of the second set of cells is detected by the UE, wherein 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 UE of claim 3 , wherein the instructions executable to inform the E-UTRAN of the failure of the second set of cells comprise instructions executable to indicate a cause of the failure.
