Abstract
(EN)
An embodiment of a system for operating a communications controller for a group of user equipments engaged in a DMC link in a wireless communications system is provided. The communications controller is configured to allocate a set of subframes in one periodic group of subframes to the group of UEs for the DMC link, signal the set of allocated subframes to the group of UEs, and transmit parameters related to a group of HARQ processes of the DMC link. In an embodiment, the communication controller uses HARQ processes for cellular UE transmission that are determined independently from HARQ processes of the group of HARQ processes for the DMC link, and the parameters are configured to enable the group of UEs to manage the group of HARQ processes for the DMC link.

La présente invention se rapporte, dans un mode de réalisation, à un système permettant de faire fonctionner un dispositif de contrôle des communications d'un groupe d'équipements utilisateurs engagés dans une liaison DMC dans un système de communication sans fil. Le dispositif de contrôle des communications est configuré pour allouer un ensemble de sous-trames dans un groupe périodique de sous-trames au groupe d'équipements utilisateurs (UE pour User Equipment) pour la liaison DMC, signaler l'ensemble de sous-trames allouées au groupe d'équipements utilisateurs et transmettre des paramètres qui se rapportent à un groupe de processus de requête de répétition automatique hybride (HARQ pour Hybrid Automatic Repeat ReQuest) de la liaison DMC. Selon un mode de réalisation, le dispositif de contrôle des communications utilise des processus de requête HARQ du groupe de processus de requête HARQ pour la liaison DMC et les paramètres sont configurés pour permettre au groupe d'équipements utilisateurs de gérer le groupe de processus de requête HARQ pour la liaison DMC.
