Claim 4:
5. The method of claim 4, wherein the feedback condition comprises at least one of the following conditions:
a value of signal energy of a corresponding time-frequency resource detected by the second V2X device being less than a preset signal energy threshold;
the value of the signal energy of the corresponding time-frequency resource detected by the second V2X device on the corresponding time-frequency resource being a minimum one among values of the signal energy of all time-frequency resources in a same time-domain;
the second V2X device not transmitting data other than the HARQ feedback information on a corresponding time domain resource or a corresponding time-frequency resource; or
the corresponding time-frequency resource being the time-frequency resource indicated by feedback resource indication information carried in scheduling control information for the first user data.
