Abstract

A method for dual connectivity by a user equipment (UE) is described. The method includes a radio resource control (RRC) connection reconfiguration message including control information for an addition of a second set of cell(s). The control information includes a second cell radio network temporary identifier (C-RNTI) for the second set of cell(s). The UE has a first C-RNTI for a first set of cell(s). The first C-RNTI is used in a first Medium Access Control (MAC) entity, and the second C-RNTI is used in a second MAC entity.

Claims (12)

1. A method for dual connectivity by a user equipment (UE), comprising:

receiving a radio resource control (RRC) connection reconfiguration message including control information for an addition of a second set of cell(s), wherein the control information includes a second cell radio network temporary identifier (C-RNTI) for the second set of cell(s), the UE has a first C-RNTI for a first set of cell(s), the first C-RNTI is used in a first Medium Access Control (MAC) entity, and the second C-RNTI is used in a second MAC entity.

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

sending, to a user equipment (UE), a radio resource control (RRC) connection reconfiguration message including control information for an addition of a second set of cell(s) to the UE, wherein the control information includes a second cell radio network temporary identifier (C-RNTI) for the second set of cell(s), the UE has a first C-RNTI for a first set of cell(s), the first C-RNTI is used in a first Medium Access Control (MAC) entity, and the second C-RNTI is used in a second MAC etity.

3. A user equipment (UE) for dual connectivity, comprising:

a processor;

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

receive a radio resource control (RRC) connection reconfiguration message including control information for an addition of a second set of cell(s), wherein the control information includes a second cell radio network temporary identifier (C-RNTI) for the second set of cell(s), the UE has a first C-RNTI for a first set of cell(s), the first C-RNTI is used in a first Medium Access Control (MAC) entity, and the second C-RNTI is used in a second MAC entity.

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

a processor;

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

send, to a user equipment (UE), a radio resource control (RRC) connection reconfiguration message including control information for an addition of a second set of cell(s) to the UE, wherein the control information includes a second cell radio network temporary identifier (C-RNTI) for the second set of cell(s), the UE has a first C-RNTI for a first set of cell(s), the first C-RNTI is used in a first Medium Access Control (MAC) entity, and the second C-RNTI is used in a second MAC entity.
