Abstract

A method and apparatus for allocating physical cell identities (PCIs) in a wireless communication system is provided. An eNodeB (eNB) allocates PCIs for split cells of an active antenna system (AAS), and transmits information on range of the allocated PCIs for split cells of the AAS to user equipments (UEs) or neighbor eNBs.

Claims (16)

1. A method for allocating, by an eNodeB (eNB), physical cell identities (PCIs) in a wireless communication system, the method comprising:

allocating PCIs for split cells of an active antenna system (AAS); and

transmitting information on a range of the allocated PCIs for split cells of the AAS,

wherein the range of the allocated PCIs does not overlap with a range of PCIs for normal cells of the AAS.

2. The method of claim 1 , wherein the information on the range of the allocated PCIs for split cells of the AAS is transmitted to a plurality of user equipments (UEs).

3. The method of claim 2 , wherein the information on the range of the allocated PCIs for split cells of the AAS is broadcast.

4. The method of claim 1 , wherein the information on the range of the allocated PCIs for split cells of the AAS is transmitted to neighbor eNBs.

5. An eNodeB (eNB) in a wireless communication system, the eNB comprising:

a radio frequency (RF) unit configured to transmit or receive a radio signal; and

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

allocate PCIs for split cells of an active antenna system (AAS), and

transmit information on a range of the allocated PCIs for split cells of the AAS,

wherein the range of the allocated PCIs does not overlap with a range of PCIs for normal cells of the AAS.

6. The eNB of claim 5 , wherein the information on the range of the allocated PCIs for split cells of the AAS is transmitted to a plurality of user equipments (UEs).

7. The eNB of claim 6 , wherein the information on the range of the allocated PCIs for split cells of the AAS is broadcast.

8. The eNB of claim 5 , wherein the information on the range of the allocated PCIs for split cells of the AAS is transmitted to neighbor eNBs.
