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: Embodiments of this application relate to the field of wireless communication, and provide a sidelink control information sending method and a device. After obtaining first information, a second terminal device may send sidelink control information to a first terminal device based on the first information, where the first information includes indication information indicating a type of the sidelink control information or includes characteristic information. The first terminal device may determine the type of the sidelink control information based on the first information, and further may blindly detect only a type of sidelink control information that the first terminal device needs to detect. This reduces complexity of blindly detecting the sidelink control information by the first terminal device.

Abstract: An information transmission method, is provided, including, a terminal determines attribute information of uplink information based on a beam identifier, and sends the uplink information to a network side device based on the attribute information. After receiving the uplink information, the network side device determines the beam identifier based on the uplink information. In this process, the terminal implicitly indicates beam IDs of different selected beams by using attribute information of reported uplink information. Different beams correspond to different attribute information of the uplink information. In other words, each beam corresponds to specific attribute information of the uplink information. Implicitly indicating a beam ID to the network side device reduces LTE standardization complexity and reduces signaling overheads.

Abstract: The present disclosure pertains to the field of communications technologies and discloses a method and an apparatus for sending feedback information. The method includes: receiving transport block control information sent by a base station on a first time-frequency resource in a downlink (DL); determining a time domain resource of a second time-frequency resource based on a resource location of the first time-frequency resource, duration of a first transmission time interval in the DL, and duration of a second transmission time interval in an uplink (UL); and sending feedback information on the second time-frequency resource in the UL, where the feedback information indicates a receiving status of a transport block. In the present disclosure, a success rate of receiving retransmitted transport blocks can be improved, and efficiency of data transmission can be further improved.

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.
