AI Technical Summary

Technical Problem

The probability of a User Equipment (UE) successfully completing data transmission after channel access in an unlicensed frequency band is low due to the risk of channel occupation by other technologies during sidelink mode-2 communication.

Method used

A resource selection method that involves excluding resources within a resource selection window using slot candidate resources as granularity to obtain a candidate resource set, and selecting a transmission resource for the first target data from this set, ensuring continuous transmission.

Benefits of technology

Improves the probability of successful data transmission after channel access by ensuring continuous channel occupancy, making the method more suitable for sidelink mode-2 operations in unlicensed frequency bands.

Abstract

The present disclosure provides a resource selection method, an information transmission method, an apparatus, and a terminal, which relate to the technical field of communication. The resource selection method includes: performing resource exclusion on resources in a resource selection window with a slot candidate resource as a granularity to obtain a candidate resource set; selecting a transmission resource for first target data from the candidate resource set; and transmitting the first target data to a second terminal through the transmission resource.
