Title
(EN) METHODS AND APPARATUS FOR SIDELINK COMMUNICATIONS AND RESOURCE ALLOCATION
(FR) PROCÉDÉS ET APPAREIL DESTINÉS À DES COMMUNICATIONS DE LIAISON LATÉRALE ET À UNE ATTRIBUTION DE RESSOURCE
Abstract
(EN)
Methods and systems are provided in which a UE transmits sidelink (SL) control information comprising a scheduling assignment (SA) indicating an SL transmission resource for a SL data transmission to a target UE. The SL transmission resource is based on one or more occupied SL resources identified by the UE and the SL transmission resource includes resources for an initial transmission and one or more retransmissions. The UE then transmits the SL data transmission using the SL transmission resource according to the transmitted SL control information. This is done without receiving, in a downlink control information (DCI), a grant of communication resources.
(FR)
La présente invention concerne des procédés et des systèmes dans lesquels un équipement d'utilisateur (UE) transmet des informations de commande de liaison latérale (SL) consistant en une attribution de planification (SA) indiquant une ressource de transmission de SL destinée à une transmission de données de SL à un UE cible. La ressource de transmission de SL est basée sur une ou plusieurs ressources de SL occupées identifiées par l'UE et la ressource de transmission de SL comprend des ressources destinées à une transmission initiale et une ou plusieurs retransmissions. L'UE transmet ensuite la transmission de données de SL à l'aide de la ressource de transmission de SL selon les informations de commande de SL transmises. Ceci est réalisé sans la réception, dans des informations de commande de liaison descendante (DCI), d'une autorisation de ressources de communication.
