Abstract: A data transmitting method applied with HARQ for transmitting data from a data transmission side to a data reception side. The data transmission side allocates a process, which is a transmission unit of the same data, to new transmission data and transmits the new transmission data, cyclically continues to transmit the same data of the new transmission data or an error correction code of the same data in a process same as the process until generation of another new transmission data, and allocates, when another new transmission data is generated, the process of the cyclically continued transmission to the other new transmission data and cyclically transmits the other new transmission data. The data reception side performs data combination by the HARQ using the received data to normally receive data and detect a data error or data non-reception and monitors a communication connection state with the data transmission side.

Abstract: A mobile terminal 3 judges whether or not the mobile terminal is able to make a transition to a DTX period during Active, and, when judging that the mobile terminal is able to make a transition to a DTX period during Active, notifies a base station 2 to that effect. If the base station 2 judges that the mobile terminal is able to make a transition to a DRX period during Active when triggered by the notification from the mobile terminal 3, the base station temporarily stops supply of electric power to the data transmission processing units and the data reception processing units of the mobile terminal 3.
