Abstract: Embodiments of this application provide a device-to-device based resource determining method and device, which may be applied to a D2D system (for example, a system such as an internet of vehicles, V2X, or V2V). The method includes: receiving first information sent by a first terminal device, where the first information indicates a second terminal device to send assistance information; and sending the assistance information to the first terminal device, where the assistance information is used to assist the first terminal device in selecting a resource for data transmission. The second terminal device assists the first terminal device in determining the resource for data transmission, instead of completely determining, by a terminal device that sends data, the resource for data transmission.

Abstract: This application may be applied to an internet of vehicles, for example, V2X and LTE-V. A first terminal apparatus determines, a first resource pool. The first terminal apparatus detects control information of a second terminal apparatus, where the control information indicates second service data of the second terminal apparatus, and the control information includes location information of the second terminal apparatus, a first frequency domain resource, and a periodicity of the second service data. The first terminal apparatus determines an unavailable time-frequency resource in the first resource pool based on location information of the first terminal apparatus, the location information of the second terminal apparatus, a first threshold, the first frequency domain resource, and the periodicity of the second service data. The first terminal apparatus selects a first time-frequency resource from available time-frequency resources in the first resource pool to transmit first service data.
