Abstract

Esta divulgación proporciona sistemas, métodos y aparatos para una comunicación inalámbrica. En un aspecto, se proporciona un enfoque de punto de transmisión/recepción (TRP) múltiple para retroalimentación de reconocimiento (ACK) de solicitud de repetición automática híbrida (HARQ) mediante indicadores de asignación del enlace descendente (DAI) del contador (cDAI) y DAI totales (tDAI). Por ejemplo, algunas técnicas y aparatos descritos en la presente pueden proporcionar un método de recuento conjunto en el que los cDAI y tDAI se implementan y rastrean de manera conjunta entre los TRP de un grupo de TRP múltiples. Esto puede ser útil en el escenario de backhaul ideal cuando el grupo de TRP múltiples se programa de manera conjunta y puede ser más resistente contra errores que un método de recuento separado. Algunas técnicas y aparatos descritos en la presente pueden proporcionar un método de recuento separado en el que los cDAI y tDAI se implementan y rastrean de manera separada de los TRP respectivos de un grupo de TRP múltiples.
