Abstract

A method of transmitting or receiving control information in a wireless communication system is discussed. The method in one embodiment includes transmitting indication information including an MBMS related identifier to at least one user equipment; and transmitting control information which has been changed to the at least one user equipment after the transmission of the indication information, wherein the control information is transmitted via a multicast control channel (MCCH) and a multicast channel (MCH).

Claims

1. A method of transmitting control information for a multimedia broadcast/multicast service (MBMS) in a wireless communication system, the method comprising:

transmitting indication information including an MBMS related identifier to at least one user equipment through an L1/L2 control channel; and

transmitting control information which has been changed to the at least one user equipment after the transmission of the indication information,

wherein the control information is transmitted via a multicast control channel (MCCH) and a multicast channel (MCH).

2. The method of claim 1, wherein the MCCH is a logical channel and the MCH is a transport channel.

3. The method of claim 1, wherein the control information is transmitted through a data region.

4. The method of claim 1, wherein the indication information further includes resource information through which the control information is transmitted.

5. The method of claim 4, wherein the indication information further includes a transport format indication of the control information.

6. The method of claim 1, wherein the control information is transmitted to the at least one user equipment through resources designated by system information.

7. The method of claim 1, the indication information is periodically transmitted to the at least one user equipment.

8. The method of claim 1, wherein the MBMS related identifier is an MBMS identifier or an MBMS group identifier.

9. A method of receiving control information for a multimedia broadcast/multicast service (MBMS) in a wireless communication system, the method comprising:

receiving indication information including an MBMS related identifier from a network through an L1/L2 control channel; and

receiving control information which has been changed from the network after the reception of the indication information,

wherein the control information is received via a multicast control channel (MCCH) and a multicast channel (MCH).

10. The method of claim 9, wherein the MCCH is a logical channel and the MCH is a transport channel.

11. The method of claim 9, wherein the control information is received through a data region.

12. The method of claim 9, wherein the indication information further includes resource information through which the control information is transmitted.

13. The method of claim 12, wherein the indication information further includes a transport format indication of the control information.

14. The method of claim 9, wherein the control information is received from the network through resources designated by system information.

15. The method of claim 9, the indication information is periodically received from the network.

16. The method of claim 9, wherein the MBMS related identifier is an MBMS identifier or an MBMS group identifier.
