Abstract

Se describen un método, un dispositivo inalámbrico y un nodo de red. De acuerdo con una modalidad, un nodo de red está configurado para transmitir dentro de un mensaje de elemento de control, CE, de control de acceso a medio, MAC, una indicación de una pluralidad Kj de estados de indicación de configuración de transmisión, TCI, que son mapeados a un solo punto de código, j, en un campo de indicación de configuración de transmisión, TCI, de información de control de enlace descendente, DCI, Kj y j siendo números enteros, y transmitir dentro del mensaje de MAC CE, el número Kj de estados de TCI que son mapeados al punto de código j. En otra modalidad, un dispositivo inalámbrico está configurado para recibir dentro de un mensaje de MAC CE desde el nodo de red, una indicación de una pluralidad Kj de estados de TCI que sean mapeados a un solo punto de código, j, en un campo DCI TCI, y recibir dentro del mensaje de MAC CE, el número Kj de estados de TCI mapeados al punto de código j.
