Abstract: Embodiments of this application disclose a feedback indication method and a communications apparatus, and relate to the communications field, to unify behavior of a transmitting party and a receiving party. This ensures data transmission performance as far as possible. The method includes: A transmitting node determines a first message. A first field in the first message is set to be null, and the first field is used to indicate a time-frequency resource that carries hybrid automatic repeat request HARQ information. The transmitting node sends the first message to a receiving node. The first message is used to indicate the receiving node to delay feeding back HARQ information corresponding to a first transport block TB, or the first message is used to indicate the receiving node to give up feeding back the HARQ information corresponding to the first TB. The first TB is a transport block scheduled by the first message.

Abstract: This application provides an information transmission method and apparatus, to resolve a problem of a conflict between resources used by a terminal device to send/receive information in different radio access systems, ensure successful transmission of information with a high priority, and improve communication quality. A terminal device determines information with a higher priority in first information associated with a first radio access system and second information associated with a second radio access system. Time domain resources associated with the first information and the second information are completely or partially the same. The first information is data information and the second information is synchronization information, or the first information is synchronization information and the second information is synchronization information. The terminal device sends or receives the information with the higher priority.

Abstract: 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.

Abstract: A feedback method and apparatus which are used to provide a feedback mechanism in a sidelink communications system, and may be applied to the internet of vehicles, for example, V2X, LTE-V, and V2V. The method includes: a first terminal device determines that a feedback condition is met, and sends feedback information to a second terminal device, where the feedback information includes at least one of channel state information and a receive response, and the receive response includes a positive acknowledgment, a negative acknowledgment, or discontinuous transmission. In this way, the feedback condition is set, so that the first terminal device sends the feedback information only when the feedback condition is met. In this way, resource overheads and information redundancy that are caused when each terminal device in a communication group sends feedback information are effectively avoided.
