Abstract

The present invention relates to a method and apparatus for transmitting/receiving control information for additional broadcast information in a wireless communication system. According to one aspect of the present invention, a method for transmitting control information for additional broadcast information in a wireless communication system comprises a step in which a base station transmits control information containing information on the transmission time of the additional broadcast message, and transmits the additional broadcast message at said transmission time.

Claims

1-16. -16. (canceled)

17. A method for receiving control information for an additional broadcast message by a user equipment of a wireless communication system, the method comprising:

receiving control information including a configuration change count indicating version information of the additional broadcast message;

receiving the additional broadcast message; and

updating the received additional broadcast message when the configuration change count is different from a last configuration change count saved at the user equipment.

18. The method according to claim 17, wherein the control information is received through a secondary superframe header (S-SFH).

19. The method according to claim 17, wherein the control information further includes a minimum duration of the control information.

20. The method according to claim 19, wherein the received additional broadcast message is updated when the duration of the control information including the last configuration change count saved at the user equipment is over.

21. The method according to claim 19, wherein the minimum duration of the control information is represented in a unit of superframe.

22. The method according to claim 17, wherein the additional broadcast message is received at a periodic interval.

23. The method according to claim 17, wherein the control information further includes information of a transmission time point of the additional broadcast message, and the additional broadcast message is received at the transmission time point.

24. A method for transmitting control information for an additional broadcast message by a base station of a wireless communication system, the method comprising:

transmitting control information including a configuration change count indicating version information of the additional broadcast message; and

transmitting the additional broadcast message.

25. The method according to claim 24, wherein the control information is transmitted through a secondary superframe header (S-SFH).

26. The method according to claim 24, wherein the control information further includes a minimum duration of the control information.

27. The method according to claim 26, wherein the minimum duration of the control information is represented in a unit of superframe.

28. The method according to claim 24, wherein the additional broadcast message is transmitted at a periodic interval.

29. The method according to claim 24, wherein the control information further includes information of a transmission time point of the additional broadcast message, and the additional broadcast message is transmitted at the transmission time point.

30. A user equipment of a wireless communication system for receiving control information for an additional broadcast message, the user equipment comprising:

a reception module for receiving control information including a configuration change count indicating version information of the additional broadcast message and for receiving the additional broadcast message; and

a processor for updating the received additional broadcast message when the configuration change count is different from a last configuration change count saved at the user equipment.

31. The user equipment according to claim 30, wherein the control information is received through a secondary superframe header (S-SFH).

32. The user equipment according to claim 30, wherein the control information further includes a minimum duration of the control information, and the processor updates the received additional broadcast message when the duration of control information including the last configuration change count saved at the user equipment is over.

33. A base station of a wireless communication system for transmitting control information for an additional broadcast message, the base station comprising:

a processor for generating control information including a configuration change count indicating version information of the additional broadcast message; and

a transmission module for transmitting the control information and the additional broadcast message.

34. The base station according to claim 33, wherein the control information is transmitted through a secondary superframe header (S-SFH).

35. The base station according to claim 33, wherein the control information further includes a minimum duration of the control information.
