Abstract

Des modes de réalisation de la présente demande concernent un procédé et un dispositif de communication sans fil. Un dispositif de réseau peut configurer une ressource d'octroi de liaison latérale raisonnable, ce qui permet d'optimiser la communication de liaison latérale. Le procédé de communication sans fil comprend les étapes suivantes : un dispositif d'extrémité de transmission transmet, à un dispositif de réseau, un rapport d'état de tampon (BSR) pour une communication de liaison latérale, le BSR comprenant les informations de tampon de données d'au moins une première adresse cible et/ou les informations de tampon de données d'au moins une seconde adresse cible ; un champ de taille de tampon dans les informations de tampon de données de l'au moins une première adresse cible est défini comme étant une valeur de tampon de données correspondante ; et un champ de taille de tampon dans les informations de tampon de données de l'au moins une seconde adresse cible est défini comme étant égal à zéro.
