Title
(EN) HARQ FEEDBACK FOR SIDELINK COMMUNICATION
(FR) RÉTROACTION HARQ POUR COMMUNICATION DE LIAISON LATÉRALE
Abstract
(EN)
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive one or more sidelink communications on a sidelink between the UE and another UE. The UE may transmit one or more hybrid automatic repeat request (HARQ) feedback communications, associated with the one or more sidelink communications, on the sidelink and in a HARQ feedback resource included in a multi-slot feedback reporting period. The HARQ feedback resource may include a set of negative acknowledgement (NACK) resources or the set of NACK resources and a set of acknowledgement (ACK) resources. Numerous other aspects are provided.
(FR)
Selon divers aspects, la présente invention concerne de manière générale la communication sans fil. Selon certains aspects, un équipement utilisateur (UE) peut recevoir une ou plusieurs communication(s) de liaison latérale sur une liaison latérale entre l'UE et un autre UE. L'UE peut transmettre une ou plusieurs communication(s) de rétroaction de requête automatique de répétition hybride (HARQ), associée(s) à la ou aux communication(s) de liaison latérale, sur la liaison latérale et dans une période de rapport de rétroaction multi-créneau comportant une ressource de rétroaction HARQ. La ressource de rétroaction HARQ peut comporter un ensemble de ressources d'accusé de réception négatif (NACK) ou l'ensemble de ressources NACK et un ensemble de ressources d'accusé de réception (ACK). L'invention se présente également sous de nombreux autres aspects.
