1. A sleep method for a terminal device, comprising:
determining whether no wake-up indication signal is received within a preset time; and
based on a determination that no wake-up indication signal is received within the preset time,
stopping, by the terminal device, an activity timer when the activity timer is running, wherein the running of the activity timer starts in response to the terminal device receiving a physical downlink control channel (PDCCH); or
stopping, by the terminal device, a retransmission timer when the retransmission timer is running, wherein the terminal device monitors the PDCCH in response to the retransmission timer running;
wherein discontinuous reception (DRX) is configured for the terminal device.
