A method and device for discontinuous reception are provided, and can further reduce a power consumption of a terminal device in a DRX process. The method includes: detecting, by a terminal device, a wakeup signal in a first time period; starting a drx-onDurationTimer in a DRX cycle after the first time period if the terminal device detects the wakeup signal; and/or, not starting the drx-onDurationTimer in the DRX cycle after the first time period if the terminal device does not detect the wakeup signal.
