Abstract
(EN)
Provided in embodiments of the present application are a transmission method and device, relating to the technical field of communications. The invention is used to utilize side link transmission resources so as to increase the reliability of side link transmission. The transmission method comprises: a terminal obtaining service information as well as a resource usage model corresponding to the service information; the terminal uses the resource usage model to transmit on a side link a service corresponding to the service information. The resource usage model comprises: any one of a dedicated-resources model, a resource-competition model, and a model combining usage of dedicated resources and resource competition. In this way, when the terminal is engaged in follow-on transmission service, the terminal may select, on the basis of the service information, a resource usage model corresponding to the service information in order to transmit on a side link a service corresponding to the service information. The invention allows for the flexible use of a resource usage model and thus the effective utilization of wireless resources while ensuring service QoS requirements.

Dans certains de ses modes de réalisation, la présente invention concerne un procédé et un dispositif de transmission se rapportant au domaine technique des communications. L'invention sert à utiliser des ressources de transmission de liaison latérale de façon à augmenter la fiabilité de transmission de liaison latérale. Le procédé de transmission comprend les étapes suivantes : un terminal obtient des informations de service ainsi qu'un modèle d'utilisation de ressources correspondant aux informations de service; le terminal utilise le modèle d'utilisation de ressources pour transmettre sur une liaison latérale un service correspondant aux informations de service. Le modèle d'utilisation de ressources comprend l'un quelconque des modèles suivants : modèles de ressources dédiées, modèle de compétition de ressources, et modèle combinant l'utilisation des ressources dédiées et la compétition de ressources. De cette manière, lorsque le terminal est engagé dans un service de transmission suivant, il peut sélectionner, sur la base des informations de service, un modèle d'utilisation de ressources correspondant aux informations de service, afin de transmettre sur une liaison latérale un service correspondant aux informations de service. L'invention permet l'utilisation flexible d'un modèle d'utilisation de ressources et donc l'utilisation efficace de ressources sans fil, tout en assurant des exigences de QoS de service.
