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.

Abstract: This application discloses a data receiving method, which may be applied to Internet of Vehicles, for example, V2X, LTE-V, and V2V. A first terminal apparatus may receive first control information from a second terminal apparatus, then receive second control information from the second terminal apparatus based on the first control information, and further receive, based on the first control information and the second control information, data sent by the second terminal apparatus. Therefore, the second control information and the data can be received after blind detection is performed on the first control information for a relatively small quantity of times, thereby improving efficiency of receiving the second control information and the data.
