Resource conflict indication transmission method, apparatus, and system

An second apparatus, comprising:

• at least one processor, configured to execute a program stored in a memory, wherein when the program is executed, the second apparatus is enabled to perform:
• sending first sidelink control information, wherein the first sidelink control information indicates a first reserved resource;
• determining a second time domain position based on a first time domain position;
• determining a third frequency domain position based on a first frequency domain position,
• wherein the first time domain position and the first frequency domain position are of the first reserved resource;
• and
• receiving a resource conflict indication at the second time domain position and the third frequency domain position, wherein the resource conflict indication indicates a conflict for the first reserved resource or indicates to reselect the first reserved resource.

A non-transitory computer-readable storage medium, applied in an first apparatus, storing instructions, wherein when the instructions are run on a computer, the first apparatus is enabled to perform:

• determining a second time domain position based on a first time domain position;
• determining a third frequency domain position based on a first frequency domain position, wherein
• the first time domain position and the first frequency domain position are of a first reserved resource indicated by first sidelink control information, and the first time domain position and a second frequency domain position are of a second reserved resource indicated by second sidelink control information;
• and
• sending a resource conflict indication to a second terminal device at the second time domain position and the third frequency domain position,
• wherein the resource conflict indication indicates a conflict for the first reserved resource or indicates to reselect the first reserved resource,
• wherein the conflict is that the first reserved resource overlaps with the second reserved resource in the time domain, or the conflict is that the first reserved resource overlaps with the second reserved resource in the time domain and the frequency domain, and
• wherein the first sidelink control information is from the second terminal device.
