Abstract

A method and apparatus of operating in an idle mode to receive a paging message is provided. The user equipment wakes during a paging listening interval and receives a first part of the paging message during the paging listening interval from a base station. The paging message comprises an extension flag indicating extension of the paging listening interval. The user equipment receives a second part of the paging message during the extended paging listening interval.

Claims

1. A method of operating in an idle mode to receive a paging message in a wireless communication system, performed by a user equipment, the method comprising:

waking during a paging listening interval;

receiving a first part of the paging message during the paging listening interval from a base station, wherein the paging message comprises an extension flag indicating extension of the paging listening interval; and

receiving a second part of the paging message during the extended paging listening interval.

2. The method of claim 1, wherein, upon receiving the first part of the paging message comprising the extension flag, the user equipment remains awake to monitor the subsequent frames for the second part of the paging message during the extended paging listening interval.

3. The method of claim 2, wherein the second part of the paging message is received in an earliest frame subsequent to a paging frame in which the paging message is received.

4. The method of claim 3, wherein the second part of the paging message is received in one subframe in the earliest frame.

5. The method of claim 1, further comprising:

after receiving a complete paging message by combining the first and second part of the paging message, returning to a paging unavailable interval during which the base station does not transmit any paging message if the complete paging message confirms that there is no paging message to be delivered to the user equipment.

6. The method of claim 1, wherein, upon receiving the first part of the paging message comprising the extension flag, the user equipment remains awake to monitor the subsequent resource regions for the second part of the paging message during the extended paging listening interval.

7. The method of claim 6, wherein the resource regions are defined by a unit of superframe or subframe.

8. A user equipment for operating in an idle mode to receive a paging message in a wireless communication system, the user equipment comprising:

a memory; and

a processor operatively coupled with the memory and configured to;

wake during a paging listening interval;

receive a first part of the paging message during the paging listening interval from a base station, wherein the paging message comprises an extension flag indicating extension of the paging listening interval; and

receive a second part of the paging message during the extended paging listening interval.

9. The user equipment of claim 8, wherein, upon receiving the first part of the paging message comprising the extension flag, the processor configured to remain awake to monitor the subsequent frames for the second part of the paging message during the extended paging listening interval.

10. The user equipment of claim 9, wherein the second part of the paging message is received in an earliest frame subsequent to a paging frame in which the paging message is received.

11. The user equipment of claim 8, wherein after receiving a complete paging message by combining the first and second part of the paging message, the processor configured to return to a paging unavailable interval during which the base station does not transmit any paging message if the complete paging message confirms that there is no paging message to be delivered to the user equipment.

12. The user equipment of claim 8, wherein after receiving a complete paging message by combining the first and second part of the paging message, the processor configured to transition to an active mode if the complete paging message confirms that there is the paging message to be delivered to the user equipment.

13. A method of transmitting a paging message in a wireless communication system, performed by a base station, the method comprising:

transmitting a first part of a paging message in a first resource region pre-defined for the transmission of the paging message; and

transmitting a second part of the paging message in a second resource region,

wherein the first part of the paging message comprises a extension flag indicating the transmission of the second part of the paging message.

14. The method of claim 13, wherein the resource region is one of a superframe, a frame and a subframe.

15. A base station for transmitting a paging message in a wireless communication system, wherein the base station is configured to:

transmit a first part of a paging message in a first resource region pre-defined for the transmission of the paging message; and

transmit a second part of the paging message in a second resource region,

wherein the first part of the paging message comprises a extension flag indicating the transmission of the second part of the paging message.
