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. A method of transmitting uplink control information by a Medium Access Control (MAC) layer of a User Equipment (UE) in a wireless communication system, the MAC layer comprising a first MAC sub-layer and at least a second MAC sub-layer, the method comprising:

generating, by the at least a second MAC sub-layer, a MAC-e protocol data unit (PDU) and

transmitting the MAC-e PDU to a network via an enhanced dedicated channel,

wherein the MAC-e PDU includes only control information indicating an amount of resources required by the UE,

wherein the MAC-e PDU is transmitted in connection with a specific enhanced transport format combination indicator (E-TFCI) value,

wherein the first MAC sub-layer is a MAC-d sub-layer for handling a dedicated transport channel,

wherein the at least a second MAC sub-layer is located below the first MAC sub-layer and is for handling the enhanced dedicated channel,

wherein the specific E-TFCI value is transmitted via an enhanced dedicated physical control channel (E-DPCCH), and

wherein the specific E-TFCI value indicates to the network that the control information is transmitted alone.

2. The method of claim 1, wherein the control information comprises resource allocation request information used by the network to control scheduling.

3. The method of claim 1, wherein the control information comprises buffer status information of the UE.

4. The method of claim 1, wherein the control information comprises transmission power information of the UE.

5. The method of claim 1, wherein the at least a second MAC sub-layer comprises a MAC-e sub-layer and a MAC-es sub-layer.

6. The method of claim 5, wherein the MAC-es sub-layer sits on top of the MAC-e sub-layer.
