Communications methods and apparatus for ensuring service data transmission reliability are described. The described methods and apparatus can relate to the field of communication technologies, and in particular, to vehicle to anything (V2X), intelligent driving, an intelligent connected vehicle, and similar communication technologies. For example, a method can include a first terminal receiving service data from a second terminal. If a distance value between the first terminal and the second terminal falls within a preset distance range, the first terminal sends, based on a preset condition, acknowledgment information indicating that the service data is received successfully or unsuccessfully to the second terminal. The preset distance range is determined based on a first preset distance value and a second preset distance value, and the second preset distance value is greater than the first preset distance value. The method can be applied to a communication process between terminals.

If the terminal device does not receive the indication information, it indicates that the channel is occupied within the first COT, and the terminal device performs blind detection on the start information of the second COT.
