Method for wireless communication and terminal device

A terminal device, comprising:

• a memory configured to store computer programs;
• and
• a processor configured to invoke and execute the computer programs stored in the memory to:
• determine presence of a resource conflict on resources reserved by a second terminal device on a first time unit;
• and
• determine whether to send a resource conflict indication to the second terminal device on a target time unit;
• wherein the resource conflict indication indicates the presence of the resource conflict on the resources reserved by the second terminal device on the first time unit, the target time unit is a last time unit of at least one time unit before the first time unit, an interval between the target time unit and the first time unit is greater than or equal to a first threshold, the at least one time unit is used for transmission of sidelink (SL) feedback information, and the first threshold is associated with a sub-carrier interval of a SL carrier;
• wherein in response to the first terminal device being not a target receiving terminal for the second terminal device, in terms of determining whether to send the resource conflict indication to the second terminal device on the target time unit, the processor is configured to invoke and execute the computer programs stored in the memory to:
• determine according to a priority of a physical SL feedback channel (PSFCH) used for transmission of the resource conflict indication on the target time unit, whether to send the resource conflict indication to the second terminal device on the target time unit.
