Abstract

The present invention provides a user equipment for a telecommunications system, the telecommunications system comprising at least a first radio basestation. The user equipment comprises means for controlling a transmission power of the user equipment, such that said transmission power has a first value for a first set of one or more signals sent over a physical channel between the user equipment and the first radio basestation. The first value and said second value are different. In alternative embodiments, the second set of signals are transmitted taking into account information from the serving cell and a neighbouring cell, while the first set of signals are transmitted taking into account information from the serving cell only.

Claims

1-24. -24. (canceled)

25. A user equipment (UE) for a telecommunications system, the telecommunications system comprising at least a first radio base station, the UE comprising:

a controller configured for controlling a transmission power of the UE such that the transmission power has a first value for a first set of one or more signals sent over a physical channel between the UE and the first radio base station and has a second value for a second set of one or more signals sent over the physical channel between the UE and the first radio base station, wherein the first value and the second value are different; and

a receiver configured for receiving an indication that one or more signals from the UE interfere with a second radio base station;

wherein the UE'"'"'s transmission power is controlled based on the indication.

26. A user equipment as claimed in claim 25, wherein the second value is controlled based on the indication.

27. The UE of claim 25, wherein the first value is higher than the second value.

28. A user equipment (UE) for a telecommunications system, the telecommunications system comprising at least a first radio base station and a second radio base station, the UE comprising:

a receiver configured for receiving an indication that one or more signals from the UE interfere with the second radio base station;

a first transmission control mechanism, for a first set of one or more signals sent over a physical channel between the UE and the first radio base station, configured for disregarding the indication; and

a second transmission control mechanism, for a second set of one or more signals sent over the physical channel between the UE and the first radio base station, configured for taking into account the indication.

29. The UE of claim 28, wherein the first transmission control mechanism is adapted to control a transmission power of the UE such that the transmission power has a first value for the first set of one or more signals, the second transmission control mechanism is adapted to control the transmission power of the UE such that the transmission power has a second value for the second set of one or more signals, and the first value and the second value are different.

30. The UE of claim 29, wherein the first value is higher than the second value.

31. The UE of claim 28, wherein the first set of one or more signals comprises control signals.

32. The UE of claim 31, wherein the first set of one or more signals comprises signals relating to handover from the first base station to the second base station.

33. The UE of claim 31, wherein the first set of one or more signals comprises medium access control elements.

34. The UE of claim 31, wherein the first set of one or more signals comprises radio link control protocol or packet data convergence protocol control signals.

35. The UE of claim 31, wherein the first set of one or more signals comprises radio resource control signals.

36. The UE of claim 28, wherein the first set of one or more signals comprises signals reporting an amount of data in a buffer of the UE.

37. The UE of claim 28, wherein the second set of one or more signals comprises data signals.

38. The UE of claims 28, wherein the indication is received from the first base station.

39. The UE of claim 28, wherein the telecommunications system is a Long Term Evolution system.

40. The UE of claim 39, wherein the physical channel is a physical uplink shared channel.

41. The UE of claim 28, wherein the indication is received from the second base station.

42. The UE of claim 28, wherein the telecommunications system is a Wideband Code-Division Multiple Access system.

43. The UE of claim 42, wherein the indication is a relative grant.

44. A method in a user equipment (UE) of a telecommunications system, the telecommunications system comprising at least a first radio base station, the method comprising:

controlling a transmission power of the UE such that the transmission power has a first value for a first set of one or more signals sent over a physical channel between the UE and the first radio base station and has a second value for a second set of one or more signals sent over the physical channel between the UE and the first radio base station, wherein the first value is higher than the second value; and

receiving an indication that one or more signals from the UE interfere with a second radio base station;

wherein the transmission power is controlled based on the indication.

45. The method of claim 44, wherein the first value and the second value are controlled based on the indication.

46. The method of claim 44, wherein the indication is received from the first radio base station.

47. The method of claim 44, wherein the indication is received from the second radio base station.
