Abstract: This application provides a communication method, and a distance determining method and apparatus. A first terminal device sends a first signal. A second terminal device determines whether a location of the second terminal device is a specified area. When the location of the second terminal device is the specified area, the second terminal device sends feedback information. When the location of the second terminal device is not the specified area, the second terminal device does not send feedback information or sends less feedback information. This method is applicable to communication, for example, V2X communication or D2D communication, between terminal devices on a sidelink.

Abstract: This application provides a communication method and a communications apparatus. The communication method includes: a first terminal device determines a first parameter, where the first parameter is used to indicate a parameter of a sensing window, a parameter of a resource selection window, and/or a parameter of a first time window, and the first time window includes the sensing window and the resource selection window. The first terminal device determines a first resource pool from at least one resource pool based on the first parameter. The first terminal device selects a first resource from the first resource pool. The first terminal device transmits sidelink information on the first resource. According to the method provided in embodiments of this application, a data transmission delay can be reduced and system communication efficiency can be improved.

Abstract: This application provides a feedback information transmission method and apparatus. The method includes: obtaining, by a first terminal device, a first resource used to transmit a sidelink HARQ and a second resource used to transmit a downlink HARQ, where the sidelink HARQ is a HARQ corresponding to sidelink data sent by the first terminal device, and the downlink HARQ is a HARQ corresponding to downlink data that is received by the first terminal device from a network device; and when the first resource and the second resource overlap in time domain, sending feedback information to the network device on a third resource based on a priority of the sidelink HARQ and a first threshold, where the feedback information includes the sidelink HARQ and/or the downlink HARQ, and the first threshold may be used to represent a priority of a downlink service type.
