Abstract
(EN)
A method is disclosed for operating a user equipment (UE) for device-to-device (D2D) communications. The method includes receiving booking information from another UE. The booking information identifying a resource that the other UE is booking to use for transmission by the other UE and further including priority information. The method further includes selectively transmitting preemption signaling based on whether the received priority information indicates lower priority than local priority information that is associated with a transmission to be scheduled by the UE. The preemption signaling indicates preemption of the UE to use the resource identified by the booking information. The method further includes scheduling the UE to transmit using the resource identified by the booking information.

L'invention concerne un procédé de commande d'un équipement utilisateur (UE) pour des communications de dispositif à dispositif (D2D). Le procédé consiste à recevoir des informations de réservation, d'un autre UE. Les informations de réservation identifient une ressource que l'autre UE a réservée afin de l'utiliser pour exécuter une transmission, et comprennent en outre des informations de priorité. Le procédé consiste en outre à transmettre une signalisation de préemption de façon sélective, selon que les informations de priorité reçues indiquent une priorité inférieure à celle d'informations de priorité locale associées à une transmission devant être planifiée par l'UE. La signalisation de préemption indique que l'UE préempte la ressource identifiée par les informations de réservation, afin de l'utiliser. Le procédé consiste en outre à planifier l'UE pour une transmission à l'aide de la ressource identifiée par les informations de réservation.
