Title
(EN) HYBRID AUTOMATIC REPEAT REQUEST FEEDBACK FOR LOW LATENCY TRANSMISSIONS
(FR) RÉTROACTION DE DEMANDE DE RÉPÉTITION AUTOMATIQUE HYBRIDE POUR DES TRANSMISSIONS À FAIBLE LATENCE
Abstract
(EN)
Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for avoiding collisions between hybrid automatic repeat request (HARQ) feedback transmissions and between HARQ feedback transmissions and other transmissions. In one example, a base station may configure resources for HARQ feedback transmissions such that the resources are exclusive of each other to avoid collisions between HARQ feedback transmissions. In another example, a base station may indicate resources for a user equipment (UE) to use for HARQ feedback transmissions such that the resources are exclusive of each other to avoid collisions between HARQ feedback transmissions. In yet another example, if a HARQ feedback transmission and another transmission are scheduled on overlapping resources, a UE may be configured to multiplex bits of the HARQ feedback transmission and the other transmission or drop the other transmission.

L'invention concerne des procédés, des systèmes et des dispositifs de communication sans fil. De manière générale, les techniques de l'invention permettent d'éviter des collisions entre des transmissions de rétroaction de demande de répétition automatique hybride (HARQ) et entre des transmissions de rétroaction HARQ et d'autres transmissions. Dans un exemple, une station de base peut configurer des ressources pour des transmissions de rétroaction HARQ afin que les ressources soient exclusives l'une de l'autre pour éviter les collisions entre les transmissions de rétroaction HARQ. Dans un autre exemple, une station de base peut indiquer des ressources pour un équipement utilisateur (UE) à utiliser pour des transmissions de rétroaction HARQ afin que les ressources soient exclusives l'unes de l'autre pour éviter les collisions entre les transmissions de rétroaction HARQ. Dans encore un autre exemple, si une transmission de rétroaction HARQ et une autre transmission sont planifiées sur des ressources se chevauchant, un UE peut être configuré pour multiplexer les bits de la transmission de rétroaction HARQ et de l'autre transmission ou abandonner l'autre transmission.
