Abstract

A method for controlling a user equipment (UE) capable of receiving a point-to-multipoint service in a wireless communication system comprises receiving the point-to-multipoint service on a physical channel from a network. The method also comprises receiving a first scheduling indicator associated with a number of scheduling periods where there is no transmission related to the point-to-multipoint service, wherein each scheduling period is associated with a scheduling indicator. The method also comprises receiving the point-to-multipoint service through the physical channel after the number of scheduling periods where there is no transmission. The point-to-multipoint service and the first scheduling indicator are received on the same physical channel. The method may further comprise receiving a second scheduling indicator after the number of scheduling periods where there is no transmission. The method may further comprise receiving the point-to-multipoint service through the physical channel in response to the second scheduling indicator.

Claims

1. A method for controlling a user equipment (UE) capable of receiving a point-to-multipoint service in a wireless communication system, the method comprising:

receiving the point-to-multipoint service on a physical channel from a network;

receiving a first scheduling indicator associated with a number of scheduling periods where there is no transmission related to the point-to-multipoint service, wherein each scheduling period is associated with a scheduling indicator; and

receiving the point-to-multipoint service through the physical channel after the number of scheduling periods where there is no transmission;

wherein, the point-to-multipoint service and the first scheduling indicator are received on the same physical channel.

2. The method of claim 1, further comprising receiving a second scheduling indicator after the number of scheduling periods where there is no transmission.

3. The method of claim 2, further comprising receiving the point-to-multipoint service through the physical channel in response to the second scheduling indicator.

4. The method of claim 1, wherein the same physical channel comprises a common physical channel.

5. The method of claim 4, wherein the common physical channel comprises an SCCPCH (secondary common physical channel).

6. The method of claim 3, wherein the point-to-multipoint service, the first scheduling indicator and the second scheduling indicator are received on different logical channels.

7. The method of claim 6, wherein the first scheduling indicator and the second scheduling indicator are received on the same logical channel.

8. The method of claim 7, wherein the point-to-multipoint service is received on a MTCH (MBMS traffic channel).

9. The method of claim 7, wherein the point-to-multipoint service is received on a different type of logical channel.

10. The method of claim 1, wherein the network is a UTMS terrestrial radio network (UTRAN).

11. A method in a network for controlling a user equipment (UE) capable of receiving a point-to-multipoint service in a wireless communication system, the method comprising:

transmitting the point-to-multipoint service on a physical channel;

determining a number of scheduling periods where there is no transmission related to the point-to-multipoint service;

transmitting a first scheduling indicator associated with the number of scheduling periods where there is no transmission, wherein each scheduling period is associated with a scheduling indicator; and

transmitting the point-to-multipoint service through the physical channel after the number of scheduling periods where there is no transmission;

wherein, the point-to-multipoint service and the first scheduling indicator are transmitted on the same physical channel.

12. The method of claim 11, further comprising transmitting a second scheduling indicator after the number of scheduling periods where there is no transmission.

13. The method of claim 11, wherein the same physical channel comprises a common physical channel.

14. The method of claim 11, wherein the common physical channel comprises an SCCPCH (secondary common physical channel).

15. The method of claim 11, wherein the point-to-multipoint service, the first scheduling indicator and the second scheduling indicator are received on different logical channels.

16. The method of claim 15, wherein the first scheduling indicator and the second scheduling indicator are received on the same logical channel.

17. The method of claim 16, wherein the point-to-multipoint service is received on a MTCH (MBMS traffic channel).

18. The method of claim 17, wherein the point-to-multipoint service is received on a different type of logical channel.

19. The method of claim 11, wherein the network is a UTMS terrestrial radio network (UTRAN).

20. A user equipment (UE) capable of receiving a point-to-multipoint service in a wireless communication system, the user equipment comprising:

means for receiving the point-to-multipoint service on a physical channel from a network;

means for receiving a first scheduling indicator associated with a number of scheduling periods where there is no transmission related to the point-to-multipoint service, wherein each scheduling period is associated with a scheduling indicator; and

means for receiving the point-to-multipoint service through the physical channel after the number of scheduling periods where there is no transmission;

wherein, the point-to-multipoint service and the first scheduling indicator are received on the same physical channel.

21. The user equipment of claim 20, further comprising means for receiving a second scheduling indicator after the number of scheduling periods where there is no transmission.

22. The user equipment of claim 21, further comprising means for receiving the point-to-multipoint service through the physical channel in response to the second scheduling indicator.

23. A network for controlling a user equipment (UE) capable of receiving a point-to-multipoint service in a wireless communication system, the network comprising:

means for transmitting the point-to-multipoint service on a physical channel;

means for determining a number of scheduling periods where there is no transmission related to the point-to-multipoint service;

means for transmitting a first scheduling indicator associated with the number of scheduling periods where there is no transmission, wherein each scheduling period is associated with a scheduling indicator; and

means for transmitting the point-to-multipoint service through the physical channel after the number of scheduling periods where there is no transmission;

wherein, the point-to-multipoint service and the first scheduling indicator are transmitted on the same physical channel.

24. The network of claim 23, further comprising means for transmitting a second scheduling indicator after the number of scheduling periods where there is no transmission.

25. The network of claim 23, wherein the point-to-multipoint service and the first scheduling indicator are received on a common physical channel.
