1. A method for indicating a feedback mode, comprising:
obtaining, by a first device, configuration information, wherein the configuration information is configured to indicate whether the first device supports an optional function of hybrid automatic repeat request (HARQ) feedback, and the optional function is configured to perform HARQ feedback based on a distance between a receiving end and a sending end; and
sending, by the first device, sidelink control information (SCI) to a second device based on the configuration information, wherein the SCI comprises a first type of SCI and a second type of SCI, one of the first type of SCI or the second type of SCI comprises a first field, and the first field is configured to indicate a HARQ feedback mode for data transmission in multicast communication;
wherein when the configuration information indicates that the first device supports the optional function of HARQ feedback, the first type of SCI comprises the first field; and
when the configuration information indicates that the first device does not support the optional function of HARQ feedback, the second type of SCI comprises the first field.
