Discontinuous data transmittion/reception method

A discontinuous data transceiving method is provided to enable a terminal to transmit upstream feedback related to downstream data to a wireless network, when the terminal receives the downstream data. A method used when a terminal(100) receives data from a wireless network comprises the following steps. According to the first discontinuous cycle, downstream data are received during operation. The response message to the downstream data is transmitted. After transmission of the response message, the terminal operates in the second discontinuous cycle. The first discontinuous cycle is the long DRX and the second discontinuous cycle is the short DRX.
