Methods for multi-point carrier aggregation configuration and data forwarding
First Claim
1. A method, comprising:
- establishing a primary connection in a primary cell belonging to a primary base station with a first UE-ID, wherein the primary cell comprises a downlink component carrier (CC) and an uplink CC;
establishing a second connection in a secondary cell belonging to a second base station with a second UE-ID, and wherein the secondary cell comprises a downlink CC and an uplink CC;
aggregating component carriers based on the first UE-ID and the second UE-ID;
receiving a configuration that configures the uplink CC of the secondary cell as a feedback channel for the downlink CC of the second connection;
performing a radio link monitoring (RLM) function on the second connection; and
suspending uplink transmissions of the second connection when a radio link failure (RLF) of the second connection occurs.

Abstract
Methods of multi-point carrier aggregation configuration and data forwarding are disclosed. In one embodiment of the invention, a primary connection is established between a UE and a primary base station in a primary cell with a first UE-ID. A second connection is configured between the UE and a second base station in a secondary cell with a second UE-ID. Component carriers from the primary and the second connections are configured and aggregated. Mobility management functions are performed on the primary connection. In another embodiment of the current invention, a first UE data is received from a primary connection with a UE connecting to a first base station, a second UE data is received from a second base station. The first UE data and the second UE data are combined. A third UE data from a network entity is distributed to the first and the second base station.

8. A user equipment (UE), comprising:
-
memory that contains a set of program instructions; a radio frequency (RF) transceiver that transmits and receives radio signals; and a processor that executes the set of program instructions in accordance with the radio signals and thereby controls the UE to perform the steps of; establishing a primary connection in a primary cell belonging to a primary base station with a first UE-ID, wherein the primary cell comprises a downlink component carrier (CC) and an uplink CC, wherein a second connection is established in a secondary cell belonging to a second base station with a second UE-ID, and wherein the secondary cell comprises a downlink CC and an uplink CC; aggregating component carriers based on the first UE-ID and the second UE-ID; receiving a configuration that configures the uplink CC of the secondary cell as a feedback channel for the downlink CC of the second connection; performing a radio link monitoring (RLM) function on the second connection; and suspending uplink transmissions of the second connection when a radio link failure of the second connection occurs. - View Dependent Claims (9, 10, 11, 13)
