Method of transmitting/receiving a paging message in a wireless communication system

1. A method of receiving a paging message at User Equipment (UE) in a wireless communication system, the method comprising:

receiving, from a network, paging indication information including UE identification information and scheduling information for a paging channel (PCH) on which a paging message is transmitted, the scheduling information including allocation information indicating a time-frequency region through which the paging message is transmitted;

obtaining the paging indication information when the UE identification information is identical to an identity of the UE; and

receiving, from the network, the paging message through the time-frequency region indicated by the paging indication information.

2. The method of claim 1 , wherein the UE is in a radio resource control (RRC) idle mode and the UE identification information is a long UE identity.

3. The method of claim 1 , wherein the UE is in a radio resource control (RRC) connected mode and the UE identification information is a short UE identity.

4. The method of claim 1 , wherein the paging indication information is received on a paging indication channel (PICH).

5. The method of claim 1 , further comprising including the paging indication information in L1/2 control information to be transmitted.

6. The method of claim 1 , wherein the paging indication information is received on different sub-carriers and in different time intervals.

7. The method of claim 1 , wherein the paging indication information is received during a paging occasion.

8. A method of transmitting a paging message at a network in a wireless communication system, the method comprising:

transmitting, to a User Equipment (UE), paging indication information including UE identification information and scheduling information for a paging channel (PCH) on which a paging message is transmitted, the scheduling information including allocation information indicating a time-frequency region through which the paging message is transmitted; and

transmitting the paging message through the time-frequency region indicated by the paging indication information.

9. The method of claim 8 , wherein the UE is in a radio resource control (RRC) idle mode and the UE identification information is a long UE identity.

10. The method of claim 8 , wherein the UE is in a radio resource control (RRC) connected mode and the UE identification information is a short UE identity.

11. A method of receiving a paging message at a User Equipment (UE) in a wireless communication system, the method comprising:

receiving, from a network, paging indication information including UE identification information and scheduling information for a paging channel (PCH) on which a paging message is transmitted;

obtaining the received paging indication information when the UE identification information is identical to an identity of the UE; and

receiving a paging message using the paging indication information by combining a plurality of paging channels from a plurality of cells,

wherein the scheduling information includes allocation information of a time-frequency region through which the paging message is transmitted.

12. The method of claim 11 , wherein the paging indication information is received from the plurality of cells, the method further comprising:

combining the paging indication information from the plurality of cells.

13. The method of claim 11 , wherein the plurality of cells are included in one tracking area (TA).

14. The method of claim 12 , wherein the plurality of cells are included in one tracking area (TA).
