Abstract
Se divulga tecnología para determinar un tamaño de libro de claves de reconocimiento de solicitud de repetición automática híbrida (HARQ-ACK) para agregación de portadora (CA) de duplaje por división de tiempo (TDD) de ínter-banda. En un ejemplo, un equipo de usuario (UE) operable para determinar un tamaño de libro de claves de HARQ-ACK para TDD CA de inter-banda puede incluir circuitos de computadora configurados para: determinar una ventana de agrupación de HARQ para TDD CA de inter-banda que incluye un número de subtramas de enlace descendente (DL) que utilizan realimentación de HARQ-ACK; dividir la ventana de agrupación de HARQ en una primera parte y una segunda parte; y calcular el tamaño de libro de claves de HARQ-ACK con base en la primera parte y la segunda parte. La primera parte puede incluir subtramas de DL de células de servicio configuradas que ocurren no después de la subtrama de DL donde se comunica una transmisión de información de control de enlace descendente (DCI) para programación de enlace ascendente en una célula de servicio, y la segunda parte puede incluir subtramas de canal compartido de enlace descendente físico (PDSCH) que ocurren después de la transmisión de DCI de las células de servicio.
