1. A communications method, comprising:
determining, by a first terminal apparatus, a first resource pool, wherein a time-frequency resource in the first resource pool is available for transmitting at least one of sidelink service data, sidelink control information, or sidelink feedback information;
detecting, by the first terminal apparatus, control information of a second terminal apparatus, wherein the control information of the second terminal apparatus indicates second service data of the second terminal apparatus, and the control information of the second terminal apparatus comprises location information of the second terminal apparatus, a first frequency domain resource occupied by the second service data, and a periodicity of the second service data;
determining, by the first terminal apparatus, 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;
selecting, by the first terminal apparatus, a first time-frequency resource from available time-frequency resources in the first resource pool to transmit first service data, wherein the available time-frequency resource comprises a time-frequency resource remaining when the unavailable time-frequency resource is removed from the first resource pool; and
sending, by the first terminal apparatus, the first service data on the first time-frequency resource.
