摘要： Disclosed in the present application are a resource reselection method and apparatus, a device, and a storage medium, which relate to the technical field of communications. The method comprises: a terminal device determining a target selection slot and a target listen slot; according to a non-listen slot and/or a listen result within the target listen slot, excluding available resources within the target selection slot, so as to obtain a candidate resource set; and if it is determined that a first resource that has been selected by the terminal device is re-selected, selecting, from the candidate resource set, a second resource used for replacing the first resource. When the terminal device executes partial listen and performs semi-persistent transmission or periodic transmission, if it is determined, by executing a Pre-emption mechanism, that a resource is pre-empted, or it is determined, by executing a Re-evaluation mechanism, that a resource conflict occurs, communication reliability is improved by means of triggering resource reselection to avoid a resource collision.

摘要： A wireless communication method and a terminal device are provided, capable of avoiding data transmission problems due to hidden nodes and half-duplex in sidelink transmission. The method includes: transmitting, by a first terminal when a specific condition is satisfied, a reference resource set to a second terminal, the reference resource set being used by the second terminal to select a sidelink resource. On one hand, it can reduce the burden on the second terminal due to the complexity in resource selection by the second terminal when the second terminal receives reference resource sets transmitted from too many terminals. On the other hand, the first terminal only transmits the reference resource set under a specific condition, which is advantageous in that the first terminal only reports the determined reference resource set to the terminal for which the reference resource set has the highest reference value, so as to improve the reliability of subsequent data transmission.
