Feedback resource determination method and apparatus for v2x service, and storage medium and terminal

A non-transitory storage medium storing one or more programs, the one or more programs comprising computer instructions, which, when executed by a processor, cause the processor to:

• acquire a first resource set, wherein the first resource set comprises a time domain position of at least one first resource which is a transmission resource for a Physical Sidelink Shared Channel (PSSCH);
• for each of the at least one first resource, determine a candidate time domain position of a second resource corresponding to the first resource based on the time domain position of the first resource and associated feedback information, wherein the second resource is a transmission resource for a Physical Sidelink Feedback Channel (PSFCH), and the associated feedback information indicates a time difference between the PSSCH and the PSFCH;
• for each candidate time domain position, determine whether symbols occupied by the candidate time domain position comprise an unavailable symbol, wherein the unavailable symbol is a symbol that cannot be used to transmit the second resource;
• and
• determine the candidate time domain position as a time domain position of the second resource based on the symbols occupied by the candidate time domain position not comprising the unavailable symbol.

A terminal comprising a memory and a processor, wherein the memory stores one or more programs, and the one or more programs comprise computer instructions, which, when executed by a processor, cause the processor to:

• acquire a first resource set, wherein the first resource set comprises a time domain position of at least one first resource which is a transmission resource for a Physical Sidelink Shared Channel (PSSCH);
• for each of the at least one first resource, determine a candidate time domain position of a second resource corresponding to the first resource based on the time domain position of the first resource and associated feedback information, wherein the second resource is a transmission resource for a Physical Sidelink Feedback Channel (PSFCH), and the associated feedback information indicates a time difference between the PSSCH and the PSFCH;
• for each candidate time domain position, determine whether symbols occupied by the candidate time domain position comprise an unavailable symbol, wherein the unavailable symbol is a symbol that cannot be used to transmit the second resource;
• and
• determine the candidate time domain position as a time domain position of the second resource based on the symbols occupied by the candidate time domain position not comprising the unavailable symbol.
