Abstract

A method of scheduling an uplink packet transmission channel in a mobile communication system is disclosed. The method of scheduling includes determining a scope of user equipments (UEs) to be applied to a scheduling assignment for scheduling the uplink packet transmission channel, and transmitting the scheduling assignment to the user equipments included in the determined scope, wherein the scheduling assignment includes an identifier for identifying the scope of the user equipments and scheduling contents for carrying information applicable to the scheduling assignment.

Claims

1. A method of scheduling an uplink packet transmission channel in a base station, the method comprising:

transmitting a scheduling assignment in an Enhanced Absolute Grant Channel (E-AGCH), wherein the contents of the scheduling assignment comprise an identifier associated with a plurality of UE, and,

receiving an uplink data packets on an Enhanced Uplink Dedicated Channel (E-DCH) according to the contents of the scheduling assignment.

2. The method of claim 1, wherein the scheduling assignment contents further comprise information related to the the transmission of the uplink data packets and wherein two identifiers are allocated to at least one UE.

3. The method of claim 2, wherein the status of the E-DCH is determined as a function of a Rise over Thermal (RoT) value.

4. The method of claim 3, wherein the RoT value is compared to at least one pre-selected value.

5. The method of claim 4, wherein the scheduling assignment is transmitted to each of the plurality of UE if the RoT value is greater than or equal to the pre-selected value.

6. The method of claim 4, wherein the scheduling assignment is transmitted to each of the plurality of UE if the RoT value is less than the pre-selected value and greater than or equal to a second pre-selected value.

7. The method of claim 4, wherein the scheduling assignment is transmitted to each of the plurality of UE if the RoT value is less than the pre-selected value.

8. The method of claim 7, wherein the scheduling contents include a priority transmission command for the E-DCH.

9. The method of claim 2, wherein the scheduling contents include a scheduled power command for assigning a specified amount of power for the E-DCH.

10. The method of claim 2, wherein the scheduling contents include a duration command for determining a length of period the scheduling assignment remains effective.

11. The method of claim 1, further comprising:

determining the status of the E-DCH; and

determining whether the scheduling assignment is associated with each of the plurality of UE according to the status of the E-DCH.

12. The method of claim 1, wherein the scheduling assignment includes a command granting or denying transmission in the E-DCH.

13. The method of claim 1, wherein transmitting the scheduling assignment comprises:

transmitting the scheduling assignment to the plurality of UE via a shared channel in the E-AGCH, wherein the scheduling assignment is received and decoded by each of the plurality of UE.

14. The method of claim 1 further comprising:

transmitting a scheduling assignment to a specific UE according to a pre-allocated transmission channel in an Enhanced Relative Grant Channel, wherein the specific UE corresponds with the pre-allocated transmission channel.

15. The method of claim 14, wherein the scheduling assignment can be transmitted to a plurality of UE according to a corresponding plurality of pre-allocated transmission channels.

16. A method of scheduling an uplink packet transmission channel for user equipment (UE), the method comprising:

receiving a scheduling assignment in an Enhanced Absolute Grant Channel (E-AGCH), wherein the scheduling assignment comprises an identifier for a plurality of UE;

acquiring the contents of the scheduling assignment; and

,

transmitting an uplink data packet on an Enhanced Uplink Dedicated Channel (E-DCH) according to the contents of the scheduling assignment.

17. The method of claim 16, wherein one or two identifiers are allocated to each UE.

18. The method of claim 16, wherein the scheduling contents include a scheduled power command for assigning a specified amount of power for the uplink packet transmission.

19. The method of claim 16, wherein the scheduling contents include a duration command for determining a length of period the scheduling assignment remains effective.

20. The method of claim 16, wherein the scheduling contents include a transmission priority command for the E-DCH.

21. The method of claim 16, wherein the scheduling assignment includes a command granting or denying transmission in the E-DCH.

22. The method of claim 16, wherein each UE of a shared channel in the E-AGCH has at least one UE identifier.

23. A method of scheduling an uplink packet transmission channel in a mobile communication system, the method comprising:

a base station transmitting a scheduling assignment in an Enhanced Absolute Grant Channel (E-AGCH) for scheduling an Enhanced Uplink Dedicated Channel (E-DCH);

a plurality of user equipment (UE) receiving the scheduling assignment, wherein the content of the scheduling assignment includes an identifier associated with each of the plurality of UE, and transmitting packets through the E-DCH according to the scheduling assignment.

24. The method of claim 23, wherein the scheduling assignment comprises scheduling contents relating to the the E-DCH and one or two identifiers allocated to each UE.

25. The method of claim 24, wherein the scheduling contents include a scheduled power command for assigning a specified amount of power for the E-DCH.

26. The method of claim 24, wherein the scheduling contents include a duration command for determining a length of period the scheduling assignment remains effective.

27. The method of claim 24, wherein the scheduling contents include a transmission priority command associated with the E-DCH.

28. The method of claim 23, further comprising;

determining the status of the E-DCH; and

determining whether the scheduling assignment is associated with each of the plurality of UE according to the status of the E-DCH.

29. The method of claim 23, wherein the status of the E-DCH is based on a Rise over Thermal (RoT) value.

30. The method of claim 29, wherein the RoT value is compared to at least one pre-selected value.

31. The method of claim 30, wherein the scheduling assignment is transmitted to each UE if the RoT value is greater than or equal to the pre-selected value.

32. The method of claim 30, wherein the scheduling assignment is transmitted to each UE if the RoT value is less than the pre-selected value but greater than or equal to a second pre-selected value.

33. The method of claim 30, wherein the same scheduling assignment is transmitted to each UE if the RoT value is less than the pre-selected value.

34. The method of claim 23, wherein the scheduling assignment includes a command granting or denying transmission for the E-DCH.

35. The method of claim 23, wherein transmitting the scheduling assignment comprises:

transmitting the scheduling assignment to the plurality of UE via a shared channel in the E-AGCH, and wherein the scheduling assignment is received and decoded by each UE.

36. The method of claim 23 further comprising:

transmitting the scheduling assignment to a specific UE according to a pre-allocated transmission channel in an Enhanced Relative Grant Channel, wherein the specific UE corresponds with the pre-allocated transmission channel.

37. The method of claim 36, wherein the scheduling assignment can be transmitted to a plurality of UE according to corresponding plurality of pre-allocated transmission channels.

38. The method of claim 23, wherein at least one UE identifier applies to a plurality of UE of a shared channel in an Enhanced Absolute Grant Channel.
