Abstract
(EN)
A resource collision solution method and apparatus in a V2X direct link communication scene, and a storage medium, relating to the technical field of communications. The method comprises: a first device receives resource allocation information respectively sent by n second devices, wherein n is an integer greater than 1 (201); the first device determines, according to the resource allocation information sent by the second devices, resources allocated by the second devices (202); if a resource allocated by a target second device in the n second devices meets a resource collision condition, the first device executes the resource collision solution procedure (203). By means of the mode, the occurrence of resource collision can also be detected for the resource which is planned to be occupied in future in the V2X direct link communication scene, the probability that the resource collision problem is solved is improved, the occurrence of resource collision is avoided to the maximum extent, the success rate of information transmission and reception in the V2X direct link communication scene is fully ensured, and the spectrum efficiency is facilitated improving.

La présente invention concerne un procédé et un appareil de solution de collision de ressources dans une scène de communication de liaison directe V2X, et un support d'informations, se rapportant au domaine technique des communications. Le procédé consiste : à recevoir, par un premier dispositif, des informations d'attribution de ressources envoyées respectivement par n seconds dispositifs, n étant un nombre entier supérieur à 1 (201) ; à déterminer, par le premier dispositif, en fonction des informations d'attribution de ressources envoyées par les seconds dispositifs, des ressources attribuées par les seconds dispositifs (202) ; si une ressource attribuée par un second dispositif cible dans les n seconds dispositifs satisfait une condition de collision de ressources, à exécuter, par le premier dispositif, la procédure de solution de collision de ressources (203). Au moyen du mode, l'apparition d'une collision de ressources peut également être détectée pour la ressource qui devrait être occupée à l'avenir dans la scène de communication de liaison directe V2X, la probabilité que le problème de collision de ressources est résolu est améliorée, l'apparition d'une collision de ressources est évitée au maximum, le taux de réussite de transmission et de réception d'informations dans la scène de communication de liaison directe V2X est complètement assuré, et l'efficacité de spectre est amélioré.
