Abstract: A feedback information sending method and an apparatus are provided. A first communications apparatus may determine sidelink feedback information, and send a reference signal to a second communications apparatus, where the reference signal carries the sidelink feedback information. In this way, terminals can send and receive the sidelink feedback information by using the reference signal, to improve transmission efficiency of the sidelink feedback information. When the terminal needs to send both a control channel or a data channel and feedback information in a same slot, this method avoids a problem that the terminal needs to simultaneously send two channels, e.g., the control channel (or the data channel) and a feedback channel, avoids reducing original transmission efficiency of the control channel or the data channel, and implements compatibility between sending through the control channel (or the data channel) and feedback through the feedback channel.

Abstract: Embodiments of this application disclose a message transmission method and apparatus, a terminal, and a base station. In the method, a symbol or symbol group may be used as a granularity to select a plurality of symbols or symbol groups from one or more slots and then allocate the plurality of symbols or symbol groups to a same terminal for transmitting data. The plurality of symbols or symbol groups may be used for uplink data scheduling or may be used for downlink data scheduling. Therefore, a slot resource is allocated at a small granularity, so that a time domain resource is more flexibly allocated, and the slot resource is more fully utilized. This helps improve message transmission efficiency, thereby expanding a coverage area.
