Abstract

Un método (600) utilizado en un Equipo de Usuario, UE, para notificar la Solicitud de Repetición Automática Híbrida, HARQ, acuse de recibo, ACK /no acuse de recibo, NACK, para Canales Físicos Compartidos en el Enlace Descendente, PDSCH, en configuraciones dúplex por división dinámica en el tiempo, TDD, que comprende: recibir (610) una pluralidad de PDSCH en subtramas en el Enlace Descendente, DL, asociadas con una subtrama en el Enlace Ascendente, UL, e indicadas por una configuración TDD de referencia en el DL; dividir (620) las subtramas en el DL en un primer subconjunto de subtramas en el DL y un segundo subconjunto de subtramas en el DL, en el que el primer subconjunto de subtramas en el DL también se indica mediante una configuración TDD de referencia en el UL; asignar (630) un primer conjunto de índices de recursos en el Canal Físico de Control en el Enlace Ascendente, PUCCH, basándose en los recursos utilizados en la transmisión de los Canales Físicos de Control en el Enlace Descendente, PDCCH, correspondientes a los PDSCH recibidos en las subtramas en el DL del primer subconjunto de subtramas en el DL; asignar (640) un segundo conjunto de índices de recursos PUCCH basándose en los recursos utilizados en la transmisión de los PDCCH correspondiente a los PDSCH recibidos en las subtramas en el DL del segundo subconjunto de subtramas en el DL; para cada uno de los PDSCH recibidos, notificar (650) el ACK/NACK HARQ utilizando los recursos PUCCH según un orden del primer conjunto asignado de índices de recursos PUCCH para los PDSCH recibidos en las subtramas en el DL del primer subconjunto de subtramas en el DL y según un orden del segundo conjunto asignado de índices de recursos PUCCH para los PDSCH recibidos en las subtramas en el DL del segundo subconjunto de subtramas en el DL; y determinar un desplazamiento entre el primer conjunto de índices de recursos PUCCH y el segundo conjunto de índices de recursos PUCCH; caracterizado por que el método comprende además determinar diferentes posiciones de inicio para el primer conjunto de índices de recursos PUCCH y para el segundo conjunto de índices de recursos PUCCH a partir del desplazamiento mediante la determinación una posición de inicio para el primer subconjunto de subtramas en el DL a partir de la notificación emitida por una estación base respectiva, BS, y determinar una posición de inicio para el segundo subconjunto de subtramas en el DL a partir de una notificación del desplazamiento para el segundo subconjunto a través de Control de Recursos de Radio, RRC, señalización o Control de Acceso a los Medios, MAC, Elemento de Control, CE.
