Title
(EN) ACKNOWLEDGMENT FEEDBACK TECHNIQUES IN WIRELESS COMMUNICATIONS
(FR) TECHNIQUES DE RENVOI D’ACQUITTEMENT DANS DES COMMUNICATIONS SANS FIL
Abstract
(EN)
Methods, systems, and devices for wireless communications are described that provide for unambiguous mapping between downlink control channel transmissions, downlink shared channel transmissions, and uplink acknowledgment feedback resources. The uplink acknowledgment feedback resource may be located within a same transmission time interval (TTI). A base station may configure codebook-based acknowledgment resources from a user equipment (UE), and feedback delay values may be associated with time domain resources of the downlink shared channel transmissions. In some examples, feedback delay values may be associated with particular search spaces or monitoring occasions of the downlink control channel transmissions that include resource allocations for the downlink shared channel transmissions. A UE using codebook-based acknowledgment feedback resources may thus unambiguously identify uplink resources that are to be used for transmitting the uplink acknowledgment feedback.

La présente invention concerne des procédés, des systèmes et des dispositifs pour des communications sans fil qui fournissent un mappage sans ambiguïté entre des transmissions de canal de commande de liaison descendante, des transmissions de canal partagé de liaison descendante et des ressources de renvoi d’acquittement de liaison montante. La ressource de renvoi d’acquittement de liaison montante peut être située à l’intérieur d’un même intervalle de temps de transmission (TTI). Une station de base peut configurer des ressources d’acquittement basées sur un livre de codes pour un équipement d’utilisateur (UE), et des valeurs de retard de renvoi d’informations peuvent être associées à des ressources du domaine temporel des transmissions de canal partagé en liaison descendante. Dans certains exemples, des valeurs de retard de renvoi d’informations peuvent être associées à des espaces de recherche particuliers ou à des occasions de surveillance des transmissions de canal de commande de liaison descendante qui incluent des attributions de ressource pour les transmissions de canal partagé de liaison descendante. Un UE utilisant des ressources de renvoi d’acquittement basées sur un livre de codes peut ainsi identifier sans ambiguïté des ressources de liaison montante qui doivent être utilisées pour transmettre l’information en retour d’acquittement de liaison montante.
