Abstract: Embodiments relate to a data transmission method and device. A feedback request is sent by a first device to user equipment that instructs the user equipment to feed back channel indication data to a network device. The channel indication data indicates that a channel is occupied by the first device within a time that corresponds to the channel indication data. The network device includes the first device and one additional device. The first device receives the channel indication data sent by the UE. The first device performs data transmission with the UE using the channel within the time that corresponds to the channel indication data.

Abstract: Embodiments of this application provide a communication method, apparatus, and system. The method includes: A first terminal starts a first timer after sending feedback information to a second terminal. The first timer indicates not to listen to sidelink control information and/or sidelink data information in at least one time unit after the first timer is started. In other words, within start duration of the first timer, the second terminal does not send the sidelink control information and/or the sidelink data information to the first terminal. Therefore, the first terminal does not need to listen to the sidelink control information and/or the sidelink data information within the duration. This can save energy.
