1. A method comprising:
determining, by a first terminal device, based on a first correspondence, a feedback manner type corresponding to a current transmission,
wherein the first correspondence comprises a correspondence between a first granularity and a hybrid automatic repeat request (HARQ) feedback manner, wherein the first granularity comprises at least one of: a destination address identifier for unicast, a source address identifier, a service type, a service identifier, a communication type, a logical channel identifier, a sidelink radio bearer, a HARQ process identifier, a logical channel group identifier, a transmit-end user equipment (UE) identifier, or a receive-end UE identifier, and wherein the feedback manner type comprises HARQ enabled/disabled information, and the HARQ enabled/disabled information is used to indicate whether to perform feedback;
obtaining, by the first terminal device, a transmission resource;
when the transmission resource does not carry property information:
obtaining, by the first terminal device, the destination address identifier with a highest priority, and
using a HARQ feedback manner corresponding to the destination address identifier, as a HARQ feedback manner supported by the transmission resource;
determining, by the first terminal device, from the first correspondence, at least one logical channel whose HARQ feedback manner is the same as the HARQ feedback manner supported by the transmission resource;
performing, by the first terminal device, data packet assembly processing based on the feedback manner type; and
sending, by the first terminal device, a data packet by using the transmission resource in the at least one logical channel.
