Abstract:
1. A method of transmitting data from a mobile station to a fixed station via a first dedicated physical data channel and a second dedicated physical data channel which are disposed in an uplink direction from the mobile station to the fixed station, said method comprising: estimating a transmit power margin which is a transmit power to be assigned to the transmission of the second dedicated physical data channel by using a maximum transmit power value configured by the fixed station which is set to a lower value than a maximum transmit power value which said mobile station can output; evaluating a state of candidate E-TFCs (E-DCH (Enhanced Dedicated Channel) Transport Format Combination) when setting the data transmission via said second dedicated physical data channel by using the estimated transmit power margin; selecting one of E-TFC to be used for the data transmission via said second dedicated physical data channel from said candidates, by using scheduling result information controlling the transmission of said second dedicated physical data channel and a result of the evaluation; and transmitting said data to said fixed station with transmit power calculated based on the selected E-TFC.
