Abstract: Embodiments of the present invention provide a method that includes: A network device and a terminal device determine a backoff time for a current frame, performs a CCA based on the backoff time, obtains an assessment result of the CCA, and sends a pilot when the assessment result of the CCA is that a channel is in an idle state; the terminal device listens on the channel based on the backoff time, and sends or receives data over the channel after detecting the pilot sent by the network device. This resolves a problem that a large quantity of electricity is wasted because the terminal device needs to keep listening on the channel when the network device is in an LBT process. The terminal device listens on the channel based on the backoff time; in another time period, the terminal device does not listen and may enter a sleep state.

Abstract: The disclosure provides communication methods and apparatuses. One example method includes that the first access network device obtains a correspondence between the first terminal apparatus and the second terminal apparatus. After obtaining a data packet, the first access network device sends a same data packet to the first terminal apparatus and the second terminal apparatus based on the correspondence, so that the first terminal apparatus and the second terminal apparatus transmit the same data packet to the slave station device.
