Abstract:
1. A mobile communication method for transmitting an Enhanced Dedicated Physical Data Channel (E-PDPCH) from a mobile station to a radio base station, comprising the steps of: transmitting, from the mobile station, a Dedicated Physical Control Channel (DPCCH) to which a retransmission control processing is not applied, at a first predetermined cycle, with a transmission power determined based on transmission power control information received from the radio base station; transmitting, from the mobile station, the Enhanced Dedicated Physical Data Channel containing a control header with user data, at a second predetermined cycle, with a transmission power having a predetermined offset relative to a transmission power of the Dedicated Physical Control Channel; wherein in the transmitting step, the mobile station transmits the Enhanced Dedicated Physical Data Channel containing the control header without the user data, when determined that no user data should be transmitted; and wherein in the transmitting step, the mobile station transmits the Enhanced Dedicated Physical Data Channel containing the control header and an error detection code without the user data, when determined that no user data should be transmitted.
