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 and a second field,

wherein the first field indicates a first identifier identifying the plurality of multiplexed channels or a second identifier not allocated to the plurality of multiplexed channels,

wherein the second field indicates information on a time interval allocated to the first identifier or the second identifier,

wherein when the first field indicates the first identifier, and the plurality of multiplexed channels are transmitted during the time interval based on the second field, and

wherein when the first field indicates the second identifier, the plurality of multiplexed channels are not transmitted during the time interval based on the second field.

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

receiving a channel other than the plurality of multiplexed channels from the base station during the time interval, when the first field indicates the second identifier.

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

4. The method according to claim 1, wherein the information on the time interval indicates a last time point of the time interval.

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

receiving second control information including information on first identifier and second identifier from a base station.

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

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

8. 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 and a second field,

wherein the first field indicates a first identifier identifying the plurality of multiplexed channels or a second identifier not allocated to the plurality of multiplexed channels,

wherein the second field indicates information on a time interval allocated to the first identifier or the second identifier,

wherein when the first field indicates the first identifier, the plurality of multiplexed channels are transmitted during the time interval based on the second field, and

wherein when the first field indicates the second identifier, the plurality of multiplexed channels are not transmitted during the time interval based on the second field.

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

transmitting a channel other than the plurality of multiplexed channels during the time interval, when the first field indicates the second identifier.

10. The method according to claim 9, wherein the channel other than the plurality of multiplexed channels is a Dedicated Traffic Channel (DTCH) or a Dedicated Control Channel (DCCH).

11. The method according to claim 8, wherein the information on the time interval indicates a last time point of the time interval.

12. The method according to claim 9, further comprising:

transmitting second control information including information on the first identifier and the second identifier.

13. The method according to claim 8, wherein the plurality of multiplexed channels includes Multicast Traffic Channels (MTCHs) which are multiplexed into one multicast channel.
