Title
(EN) RESPONDING TO A NEW DATA INDICATOR FOR A HYBRID AUTOMATIC REPEAT REQUEST PROCESS
(FR) RÉPONSE À UN INDICATEUR DE NOUVELLES DONNÉES DE PROCESSUS DE DEMANDE DE RÉPÉTITION AUTOMATIQUE HYBRIDE
Abstract
(EN) Apparatuses, methods, and systems are disclosed for responding to a new data indicator for a hybrid automatic repeat request process. One method (1200) includes determining (1202) whether a current new data indicator in a current sidelink grant matches a last received new data indicator in a last received sidelink grant for a first hybrid automatic repeat request process. The method (1200) includes, in response to determining that the current new data indicator does not match the last received new data indicator, determining (1204) whether a negative acknowledgement has been transmitted in response to the last received sidelink grant.
(FR) L'invention concerne des appareils, des procédés et des systèmes permettant de répondre à un indicateur de nouvelles données d'un processus de demande de répétition automatique hybride. Un procédé (1200) consiste à déterminer (1202) si un indicateur de nouvelles données courant compris dans une autorisation de liaison latérale courante correspond à un dernier indicateur de nouvelles données reçu compris dans une dernière autorisation de liaison latérale reçue d'un premier processus de demande de répétition automatique hybride. Le procédé (1200) consiste, en réponse à la détermination du fait que l'indicateur de nouvelles données courant ne correspond pas au dernier indicateur de nouvelles données reçu, à déterminer (1204) si un accusé de réception négatif a été transmis en réponse à la dernière autorisation de liaison latérale reçue.
