Abstract
A method for transmitting an enhanced Random Access CHannel (RACH) in a User Equipment (UE) in a mobile communication system is provided, in which the UE transmits an uplink preamble to a Node B and upon receipt of an ACKnowledgment (ACK) for the uplink preamble, transmits an Enhanced Uplink Dedicated CHannel (E-DCH) and a Dedicated Physical Control CHannel (DPCCH) to the Node B. The transmission of the DPCCH starts before the transmission of the E-DCH.
