Abstract: This specification provides a resource determining method and an apparatus, to optimize sidelink transmission performance. In this specification, a first communication apparatus may receive preferred resource information and/or non-preferred resource information, determine a transmission resource based on received resource information and a type of the first communication apparatus, and perform sidelink transmission by using the transmission resource. First resource information can indicate a high-interference or high-usage resource and/or a low-interference or low-usage resource. The first communication apparatus can select, based on the type of the first communication apparatus, a resource with relatively low interference to perform sidelink transmission. This improves sidelink transmission performance.
