Abstract

A method and apparatus for transmitting and receiving control information in a wireless communication system are provided. In a method for receiving control information of a plurality of multiplexed channels by a User Equipment (UE) in a wireless communication system, the UE receives first control information including a first field indicating a specific identifier from a base station, wherein the plurality of multiplexed channels are not transmitted during a specific time interval based on the specific identifier.

Claims

1. A method for receiving control information of a plurality of multiplexed channels by a User Equipment (UE) in a wireless communication system, the method comprising:

receiving first control information including a first field indicating a specific identifier from a base station,

wherein the plurality of multiplexed channels are not transmitted during a specific time interval based on the specific identifier.

2. The method according to claim 1, further comprising:

receiving a channel other than the plurality of channels from the base station during the specific time interval.

3. The method according to claim 2, wherein the channel other than the plurality of channels is a Dedicated Traffic Channel (DTCH) or a Dedicated Control Channel (DCCH).

4. The method according to claim 1, wherein the first control information further includes a second field indicating information on the specific time interval.

5. The method according to claim 4, wherein the information on the specific time interval indicates a last time point of the specific time interval.

6. The method according to claim 4, wherein the first control information further includes a third field indicating a channel identifier identifying one of the plurality of channels.

7. The method according to claim 6, wherein the first control information further includes a fourth field indicating a time interval in which the one of the plurality of channels is transmitted.

8. The method according to claim 6, further comprising:

receiving second control information including information on the channel identifier and the specific identifier from the base station.

9. The method according to claim 1, wherein the plurality of channels includes Multicast Traffic Channels (MTCHs) which are multiplexed into one multicast channel.

10. The method according to claim 1, wherein the specific identifier is a value that is not used among values of channel identifier fields for channel identifiers identifying the plurality of multiplexed channels.

11. A method for transmitting control information of a plurality of multiplexed channels by a base station in a wireless communication system, the method comprising:

transmitting first control information including a first field indicating a specific identifier,

wherein the plurality of multiplexed channels is not transmitted during a specific time interval based on the specific identifier.

12. The method according to claim 11, further comprising:

transmitting a channel other than the plurality of channels during the specific time interval.

13. The method according to claim 12, wherein the channel other than the plurality of channels is a Dedicated Traffic Channel (DTCH) or a Dedicated Control Channel (DCCH).

14. The method according to claim 11, wherein the first control information further includes a second field indicating information on the specific time interval.

15. The method according to claim 14;

wherein the information on the specific time interval indicates a last time point of the specific time interval.

16. The method according to claim 14, wherein the first control information further includes a third field indicating a channel identifier identifying one of the plurality of channels.

17. The method according to claim 16, wherein the first control information further includes a fourth field indicating a time interval in which the one of the plurality of channels is transmitted.

18. The method according to claim 16, further comprising:

transmitting second control information including information on the channel identifier and the specific identifier.

19. The method according to claim 11, wherein the plurality of channels includes Multicast Traffic Channels (MTCHs) which are multiplexed into one multicast channel.
