  • terminal B selects resources based on listening and uses the resources to send sideline data to terminal A. Since terminal B and terminal C are far apart, they cannot listen to each other. Therefore, B and C may choose the same transmission resource, and the data sent by terminal C will cause interference to the data sent by terminal B. This is the hidden node problem.

Therefore, when the terminal excludes resources, it will exclude all resources corresponding to this time slot in the selection window to avoid conflicts with other terminals. interference. Due to the limitation of half-duplex, the terminal excludes many resources that do not need to be excluded.
