Abstract

A method and apparatus for transmitting an indication in a wireless communication system is provided. A user equipment (UE) receives an indication, which indicates whether a cell served by an eNodeB (eNB) is a normal cell or a split cell, from the eNB, and transmits the received indication to a serving eNB of the UE.

Claims

1. A method for transmitting, by a user equipment (UE), an indication in a wireless communication system, the method comprising:

receiving an indication, which indicates whether a cell served by an eNodeB (eNB) is a normal cell or a split cell, from the eNB; and

transmitting the received indication to a serving eNB of the UE.

2. The method of claim 1, wherein the indication is broadcast by the eNB.

3. The method of claim 1, wherein the split cell is supported by an active antenna system (AAS).

4. The method of claim 1, wherein the indication further indicates whether the cell is a static cell or a temporary cell.

5. The method of claim 1, wherein the indication further indicates whether the cell is a non-UE-tracking cell or a UE-tracking cell.

6. The method of claim 1, further comprising:

transmitting measurement reports to the serving eNB.

7. A method for determining, by an eNodeB (eNB), a handover of a user equipment (UE) in a wireless communication system, the method comprising:

receiving an indication which indicates whether a neighbor cell, served by a neighbor eNB, is a normal cell or a split cell; and

determining a handover of a UE, served by the eNB, to the neighbor cell based on the received indication.

8. The method of claim 7, wherein the indication is received from the neighbor eNB via X2 interface.

9. The method of claim 7, wherein the indication is received from the UE.

10. The method of claim 7, wherein the split cell is supported by an active antenna system (AAS).

11. The method of claim 7, wherein the indication further indicates whether the cell is a static cell or a temporary cell.

12. The method of claim 7, wherein the indication further indicates whether the cell is a non-UE-tracking cell or a UE-tracking cell.

13. The method of claim 7, further comprising:

receiving measurement reports from the UE.

14. A user equipment (UE) in a wireless communication system, the UE comprising:

a radio frequency (RF) unit for transmitting or receiving a radio signal; and

a processor coupled to the RF unit, and configured to;

receive an indication, which indicates whether a cell served by an eNodeB (eNB) is a normal cell or a split cell, from the eNB; and

transmit the received indication to a serving eNB of the UE.
