1. A method of transmitting uplink control information in a user equipment (UE), the method comprising:
- composing, by at least one Medium Access Control (MAC) sub-layer in the UE, a MAC-e Protocol Data Unit (PDU) including the control information, the control information indicating an amount of resources required by the UE; and
transmitting the MAC-e PDU to a network via an Enhanced Dedicated Channel (E-DCH) which is an uplink transport channel handled by the at least one MAC sub-layer,wherein a first format of the MAC-e PDU is transmitted when the control information is included with other information in the MAC-e PDU and a second format of the MAC-e PDU is transmitted when only the control information is included in the MAC-e PDU,wherein the first format of the MAC-e PDU includes a first indicator having a first specific value to indicate that the MAC-e PDU includes the control information, andwherein a second indicator, which is transmitted via an Enhanced Dedicated Physical Control Channel (E-DPCCH), has a second specific value to indicate that the second format of the MAC-e PDU includes only the control information.
