A method for discontinuous reception and a device are provided. The method includes: a terminal device determines at least one target discontinuous reception (DRX) indication signal among multiple DRX indication signals and/or a time-frequency resource position occupied by the at least one target DRX indication signal, wherein the at least one target DRX indication signal is used for instructing the terminal device to perform a target behavior in one DRX cycle after receiving the at least one target DRX indication signal; and the terminal device detects a DRX indication signal sent by a network device according to the at least one target DRX indication signal and/or the time-frequency resource position occupied by the at least one target DRX indication signal.
