Abstract

A method of transmitting/receiving control information of a data channel for enhanced uplink data transmission is disclosed, by which efficient radio resource allocation is enabled. The present invention includes the acquiring control information of data channel for enhanced uplink data transmission; composing a Medium Access Control (MAC) Protocol Data Unit (PDU) including the control information; and transmitting the MAC PDU via a first physical channel for user data transmission.

Claims

1-37. -37. (canceled)

38. A method of transmitting uplink control information in a wireless communication system, the method comprising:

generating in a user equipment (UE), a medium access control (MAC) protocol data unit (PDU) comprising control information, wherein the control information indicates an amount of resources required by the UE; and

transmitting the MAC PDU to a network via an enhanced dedicated channel (E-DCH),

wherein the control information is transmitted alone in the MAC PDU in connection with a specific enhanced transport format combination indicator (E-TFCI) value.

39. The method of claim 38, wherein the control information comprises resource allocation request information used by the network to control scheduling.

40. The method of claim 38, wherein the control information comprises buffer status information of the UE.

41. The method of claim 38, wherein the control information comprises transmission power information of the UE.

42. The method of claim 38, wherein the MAC PDU is transmitted alone to the network.

43. The method of claim 38, wherein the specific E-TFCI value is transmitted via an enhanced dedicated physical control channel (E-DPCCH).

44. The method of claim 38, wherein the specific E-TFCI value indicates to the network that the control information is transmitted alone in the MAC PDU.

45. A method of receiving uplink control information in a wireless communication system, the method comprising:

receiving in a network via an enhanced dedicated channel (E-DCH) from a user equipment (UE), a medium access control (MAC) protocol data unit (PDU) comprising control information, wherein the control information indicates an amount of resources required by the UE; and

acquiring the control information included in the MAC PDU,

wherein the control information is received alone in the MAC PDU in connection with a specific enhanced transport format combination indicator (E-TFCI) value.

46. The method of claim 45, further comprising allocating resources to the UE using the control information.

47. The method of claim 45, wherein the control information comprises resource allocation request information used by the network to control scheduling.

48. The method of claim 45, wherein the control information comprises buffer status information of the UE.

49. The method of claim 45, wherein the control information comprises transmission power information of the UE.

50. The method of claim 45, wherein the MAC PDU is received alone from the UE.

51. The method of claim 45, wherein the specific E-TFCI value is received via an enhanced dedicated physical control channel (E-DPCCH).

52. The method of claim 45, wherein the specific E-TFCI value indicates to the network that the control information is transmitted alone in the MAC PDU.
