Title
(EN) EARLY TERMINATION OF PUSCH WITH NEW UPLINK GRANT
(FR) TERMINAISON PRÉCOCE D’UN PUSCH AVEC UNE NOUVELLE AUTORISATION DE LIAISON MONTANTE
Abstract
(EN)
A method for early termination of an ongoing uplink transmission based on implicit HARQ-ACK is disclosed. A wireless device may receive a first grant for a first uplink transmission and may begin repetitions of the first uplink transmission. The wireless device may receive a second grant for a second uplink transmission during the ongoing first uplink transmission. The wireless device may determine if the second grant is an implicit HARQ-ACK and may perform an early detection of the HARQ-ACK. The wireless device may terminate early the first uplink transmission based on the detection of the HARQ-ACK. Allowing the wireless device to terminate the first uplink transmission through an implicit HARQ-ACK frees up channel resources and saves power. The wireless device may also start the second uplink transmission earlier than a schedule time based on the early detection of the HARQ-ACK, eliminating the waste of unused uplink resources and saving power.

La présente invention concerne un procédé permettant une terminaison précoce d’une transmission de liaison montante en cours sur la base d’un HARQ-ACK implicite. Un dispositif sans fil peut recevoir une première autorisation pour une première transmission de liaison montante et peut commencer des répétitions de la première transmission de liaison montante. Le dispositif sans fil peut recevoir une seconde autorisation pour une seconde transmission de liaison montante durant la première transmission de liaison montante en cours. Le dispositif sans fil peut déterminer si la seconde autorisation est un HARQ-ACK implicite et peut réaliser une détection précoce du HARQ-ACK. Le dispositif sans fil peut terminer de manière précoce la première transmission de liaison montante sur la base de la détection du HARQ-ACK. La permission accordée au dispositif sans fil pour terminer la première transmission de liaison montante par le biais d’un HARQ-ACK implicite libère des ressources de canaux et économise de l’énergie. Le dispositif sans fil peut également démarrer la seconde transmission de liaison montante plus tôt qu’un temps planifié sur la base de la détection précoce du HARQ-ACK, ce qui élimine un gaspillage de ressources de liaison montante inutilisées et économise de l’énergie.
