Abstract

Un metodo y un sistema para que el UE y el RNC reduzcan la latencia de transmision y prevengan potencialmente la perdida de PDU tras un reajuste de la capa MAC. La generacion del UE de la PDU de estado esta acoplada con un reajuste de la capa MAC. El RNC genera un mensaje con una indicacion de reajuste de MAC (16). Despues del reajuste de la capa MAC todas las PDU almacenadas en las memorias intermedias que reordenan la capa MAC del UE (22) son niveladas a entidades RLC (24) y entonces procesadas por entidades RLC antes de la generacion de un reporte de estado de PDU (26). El reporte de estado de PDU proporciona al RNC el estado de todas las PDU recibidas exitosamente. Tras la recepcion de un reporte de estado de PDU en el RNC (28), las PDU perdidas son realizadas y retransmitidas al UE (30).

SISTEMA PARA LA RECUPERACION EFICIENTE DE DATOS ALMACENADOS TEMPORALMENTE EN EL NODO B DESPUES DEL REAJUSTE DE LA CAPA MAC CAMPO DE LA INVENCION La presente invención se relaciona con el campo de las comunicaciones inalámbricas. De manera más específica, la presente invención se relaciona con la recuperación eficiente de la transmisión de datos entre un par de entidades semejantes de petición de repetición automática (ARQ) de la Capa 2 después del reajuste de la capa MAC de un nodo intermedio desde donde son distribuidas transmisiones de datos. Un ejemplo de este escenario de traspaso es un sistema que emplea una ARQ híbrida (H-ARQ) y técnicas de modulación y codificación adaptables (AM&C) .
ANTECEDENTES Una Red de Acceso de Radio Terrestre Universal (UTRAN) de la tercera generación (3G) comprende varios controladores de red de radio (RNC) , cada uno de los cuales está asociado con uno o más Nodos B, y cada Nodo B está asociado con uno o más células. Los sistemas FDD y TDD 3G típicamente usan el RNC para distribuir, (es decir, almacenar temporalmente y programar), transmisiones de datos al UE . Sin embargo, para los canales de alta velocidad de los sistemas celulares 3G, 2 los datos son distribuidos por el Nodo B. Uno de esos canales de alta velocidad, por ejemplo, es el Canal Compartido del Enlace Descendente de Alta Velocidad (HS-DSCH) . Puesto que los datos son distribuidos por el Nodo B, es necesario almacenar temporalmente los datos para la transmisión en el Nodo B. Cuando la entidad distribuidora (Nodo B) a la cual está conectado el UE cambia, existe una pérdida potencial de los datos almacenados temporalmente en la entidad distribuidora. El RNC no tiene estado hasta la fecha de las transmisiones de las Unidades de Datos de Paquete (PDU) puesto que los datos son distribuidos por el punto intermedio (Nodo B) . Es necesario que el UE detecte la pérdida de datos y solicite su retransmisión, como con una PDU de Estado, de las PDU perdidas desde el RNC. Si la generación de la PDU de Estado se retrasa, como consecuencia, la latencia de la retransmisión de datos puede ser grande y puede no satisfacer los requerimientos de QoS . Este problema es agravado en el caso del HS-DSCH puesto que existen varios Nodos B asociados con cada RNC y existe una probabilidad mucho mayor de que un UE móvil requiera un cambio de Nodo B en lugar de un cambio de RNC como resultado de traspasos de célula del UE . El HS-DSCH utiliza la AMC para permitir la transmisión a alta velocidad de datos y utiliza la H-ARQ 3 para incrementar la posibilidad de entrega de datos exitosa. Un cambio de célula de HS-DSCH de servicio es cuando el UE tiene que cambiar la célula asociada con el punto de acceso a la UT AN que está efectuando la transmisión y la recepción del enlace de radio de HS-DSCH de servicio. El cambio de célula de HS-DSCH de servicio es invocado cuando las condiciones del canal físico mejorado y/o capacidad física mejorada es realizada en una célula alterada . Existen dos tipos de cambio de célula de HS-DSCH de servicio. Un cambio de célula de HS-DSCH de servicio Intra Nodo B es cuando el UE cambia entre dos células que están asociadas con el mismo Nodo B. Un cambio de célula de HS-DSCH de servicio Inter Nodo B es cuando el UE cambia entre dos células que están asociadas con diferentes Nodos B. En un cambio de célula Inter Nodo B, el Nodo B antes del cambio de célula de HS-DSCH de servicio es llamado el Nodo B de origen y el Nodo B después del cambio de célula de HS-DSCH de servicio es llamado el Nodo B objetivo. Existen entidades de Control de Enlace de Radio (RLC) semejantes en ambos del RNC y el UE. La entidad RLC emisora señala un número de secuencia (SN) en el encabezado de la PDU, el cual es usado por la entidad RLC receptora para asegurar que no se pierdan PDU en la transmisión. Si existen PDU perdidas durante la transmisión, realizadas por 4 la entrega fuera de secuencia de PDU, la entidad RLC receptora envía una PDU de reporte de estado para informar a la entidad RLC emisora que ciertas PDU están perdidas. La PDU de reporte de estado describe el estado de las transmisiones de datos exitosas y/o no exitosas. Identifica los SN de las PDU que están perdidas o recibidas. Si una PDU se pierde, la entidad RLC emisora retransmitirá un duplicado de la PDU perdida al RLC receptor. También es posible que la entidad RLC emisora vote por una PDU de reporte de estado de la entidad RLC receptora. La función de votación proporciona un mecanismo para que la entidad RLC emisora solicite el estado de las transmisiones de PDU. Aunque la operación de H-ARQ remueve algunas transmisiones fallidas e incrementa la probabilidad de la entrega exitosa de datos, es la capa de protocolo RLC la que finalmente asegura la entrega exitosa. Debido a los cambios dinámicos en las condiciones de propagación, el cambio de célula de HS-DSCH debe ser efectuado rápidamente para mantener la calidad de servicio. Durante el cambio de célula de HS-DSCH de servicio, es posible que el UE detenga la transmisión y la recepción en la célula de origen antes de que todas las PDU actualmente almacenadas en el Nodo B de origen sean transmitidas exitosamente. Puesto que el Nodo B de origen efectúa la programación y almacenamiento temporal de los datos, y 5 debido a que las velocidades de datos son muy altas, (por ejemplo 10 Mb/seg o más) , cuando el UE efectúa un cambio de célula de HS-DSCH de servicio (especialmente para un traspaso Inter Nodo B) existe la posibilidad de que se pierdan cantidades considerables de datos almacenados temporalmente en el Nodo B de origen. Una razón de esta pérdida de datos es que no existe mecanismo dentro de la arquitectura de la UTRAN para que los datos almacenados temporalmente en el Nodo B de origen sean transferidos al Nodo B objetivo. Tras un cambio de célula de HS-DSCH de servicio, el RNC no tiene información de cuántos, si los hay, datos se perdieron puesto que el RNC no tiene forma de saber que datos están almacenados temporalmente en el Nodo B de origen. Actualmente existen dos formas en la que los sistemas de la técnica anterior manejan la recuperación de datos almacenados temporalmente en el Nodo B de origen. Después del cambio de célula de HS-DSCH : 1) el RNC puede votar explícitamente por una PDU de estado del UE; ó 2) el RNC puede comenzar a transmitir en la célula objetivo y la entrega fuera de secuencia realizada por el UE generará la PDU de estado. En el primer caso, donde el RNC vota explícitamente por una PDU de estado, el RNC debe esperar primero hasta que el canal físico se establezca en la nueva 6 célula. La PDU de estado solicitada es entonces enviada, y es recibida y procesada por el UE . El UE genera la PDU de estado y envía esta de regreso al RNC, el cual procesa la PDU de estado y determina cuales PDU necesitan ser retransmitidas . En el segundo caso, donde el RNC comienza justamente a transmitir las PDU desde donde se detuvo en la célula de origen, el UE reconoce la entrega fuera de frecuencia de datos y genera una PDU de estado nueva para el RNC. El RNC procesa la PDU de estado y comprende cuales PDU necesitan ser retransmitidas. En cualquiera de los dos casos, si los datos almacenados temporalmente en el Nodo B de origen necesitan ser recuperados, entonces será procesada una PDU de estado, pero la recepción apropiada de los datos retransmitidos por el UE será retrasada considerablemente. Esto se debe a la generación retrasada de la PDU de estado por el UE y la recepción de la PDU de estado en el RNC. Si la transmisión está siendo efectuada en el modo reconocido RLC, los datos no son pasados a capas superiores hasta que pueda ser efectuada una entrega de datos en secuencia. En consecuencia, no se requerirá que el UE almacene temporalmente datos fuera de secuencia hasta que puedan ser retransmitidas las PDU perdidas. Esto no solo da como resultado un retraso de la transmisión, sino que requiere 7 que el UE tenga una memoria capaz de almacenar temporalmente datos para la recepción continua de datos hasta que los datos perdidos puedan ser retransmitidos exitosamente. De otro modo se reduce la velocidad de transmisión de datos efectiva, afectando por lo tanto la calidad de servicio. Puesto que la memoria es muy cara, esta es una restricción de diseño indeseable. Otro problema encontrado con el traspaso es el de los datos que son almacenados temporalmente dentro del UE . Dentro de la capa MAC, existen típicamente numerosos procesadores de H-ARQ que efectúan el procesamiento H-ARQ. Como se muestra en la Figura 1, el procesamiento H-ARQ es un esquema que comprende múltiples procesadores H-ARQ paralelos sobre el lado de transmisión (P1B-P5B) y múltiples procesadores H-ARQ paralelos correspondientes sobre el lado de la recepción (P1UE-P5UE) ¦ Cada par de procesadores, (por ejemplo P1B y PIUE) , intenta repetida y secuencialmente la transmisión de un bloque de datos hasta que la transmisión es exitosa, para asegurar que cada bloque de datos es recibido sin un error. Por cada bloque de datos, el tiempo requerido para lograr una transmisión H-ARQ exitosa varía. Puesto que varios bloques de datos son procesados en paralelo, es posible que la secuencia de transmisión no sea mantenida. Por lo tanto, una vez que es recibido un bloque de datos exitosamente por el procesador H-ARQ receptor, el 8 bloque de datos es enviado a una memoria intermedia de reordenamiento para proporcionar la entrega en secuencia a la capa RLC. Las memorias intermedias de reordenamiento reordenarán los bloques de datos sobre la base de sus números de secuencia de transmisión antes de enviarlos a la capa RLC . Durante los traspasos Inter Nodo B o Intra Nodo B, los mensajes RRC con frecuencia llevan un indicador de reajuste de la capa MAC al UE . Tras la recepción de un indicador de reajuste de la capa MAC, el UE efectúa una secuencia de funciones incluyendo, pero sin limitarse a, limpieza de las memorias intermedias para todos los procesos H-ARQ configurados, (es decir limpieza de las memorias intermedias de reordenamiento desmontando todas las PDU de la capa MAC-hs en las memorias intermedias de reordenamiento en las PDU de la capa MAC-d y proporcionando todas las PDU de la capa MAC-d a la capa MAC-d y entonces a sus entidades RLC asociadas) . Tras traspasos Inter Nodo B (y algunos traspasos Intra Nodo B) , es necesario reajustar la capa MAC-hs en el UE de modo que todos los procesos H-ARQ y todas las memorias intermedias de reordenamiento son reajustadas para la recepción de datos de una nueva entidad MAC-hs del Nodo B objetivo. Después de un cambio de célula de HS-DSCH de servicio, no puede ser obtenido el estado correcto de las 9 PDU recibidas de manera exitosa o no exitosa hasta que el procedimiento de reajuste de la capa MAC es completado y los bloques de datos son procesados por el RLC. Sería deseable tener un sistema y un método donde los datos almacenados temporalmente en el UE puedan ser contados para mantener apropiadamente los requerimientos de calidad de servicio del usuario.
LA INVENCION La presente invención es un método y un sistema para que el UE y el RNC efectúen una serie de acciones para reducir la latencia de transmisión y prevenir potencialmente pérdidas de PDU tras el reajuste de la capa MAC. La generación de la PDU de estado por el UE se acopla con el reajuste de la capa MAC. El RNC genera un mensaje de señalización con una indicación de reajuste de MAC. Después del reajuste de la capa MAC debido a la recepción de la petición de reajuste de la capa MAC, todas las PDU almacenadas en las memorias intermedias de reordenamiento de la capa MAC del UE son limpiadas a entidades RLC y entonces procesadas por entidades RLC antes de la generación de un reporte de estado de PDU. El reporte de estado de PDU proporciona el estado de todas las PDU recibidas exitosamente al RNC. Esto proporciona una generación rápida de un reporte de estado de PDU. Tras la 10 recepción de un reporte de estado de PDU en el RNC , las PDU perdidas son realizadas y retransmitidas al UE .
BREVE DESCRIPCION DE LOS DIBUJOS La Figura 1 es un diagrama de bloques de un proceso H-ARQ de la técnica anterior. La Figura 2 es un diagrama de flujo de un procedimiento eficiente de acuerdo con la presente invención para recuperación eficiente de los datos almacenados temporalmente en el UE después del cambio de célula de HS-DSCH. La Figura 3 es un diagrama de flujo de un primer método alternativo por el que el RNC espera una PDU de estado antes de iniciar la transmisión de nuevos datos en la célula objetivo. La Figura 4 es un diagrama de flujo de un segundo método alternativo por el cual el RNC espera un activador previo para iniciar una transmisión de nuevos datos en la célula objetivo.
DESCRIPCION DETALLADA DE LAS MODALIDADES PREFERIDAS Las modalidades preferidas de la presente invención serán descritas con referencia a las figuras de los dibujos donde números similares representan elementos similares a su través. 11 Refiriéndose al diagrama de flujo de la Figura 2, se muestra una primera modalidad de la presente invención la cual comprende un método 10 para determinar el estado de las transmisiones de PDU al UE con retraso mínimo después de una condición de reajuste de la capa MAC. El procedimiento comienza con el R C reconociendo la necesidad de reajustar la capa MAC del UE (paso 12) . Una posible causa para el reajuste de la capa MAC del UE es en el caso de un cambio de célula de HS-DSCH de servicio. El RNC informa al Nodo B del cambio de célula de HS-DSCH (paso 14) en el caso de un cambio de célula de HS-DSCH de servicio Inter Nodo B y también en el caso de un cambio de célula de HS-DSCH de servicio Intra Nodo B donde el Nodo B de origen es el mismo que el Nodo B objetivo, pero donde las filas de espera de transmisión no pueden ser reencaminadas de la célula de origen al objetivo. En ambos de esos casos, se requiere un reajuste de MAC. Junto con la indicación de cambio de célula de HS-DSCH, se informa al UE del requerimiento de reajuste de la capa MAC por el RNC , de acuerdo a lo indicado vía un mensaje de Control de Recursos de Radio (RRC) (paso 16) . Deberá notarse que también es posible invocar el paso 16 y avanzar al paso 14 sin consecuencias adversas. Aquellos expertos en la técnica comprenderán que existen muchas causas para reajustar la capa MAC además del 12 cambio de célula HS-DSCH, donde se aplica el método 10 para el RNC para determinar el estado de transmisión de la PDU después del reajuste de MAC. Por ejemplo, un reajuste de la capa MAC puede ser garantizado en cualquier momento que necesiten ser reiniciados procesos H-ARQ de Nodo B. Dentro del mensaje RRC, existe un identificador para que la capa MAC efectúe un reajuste. Este identificador puede ser parte del procedimiento de cambio de célula de HS-DSCH de servicio o puede ser parte de cualquier otro procedimiento que de cómo resultado el reajuste de la capa MAC en el Nodo B y el UE en cualquier cambio de célula Inter Nodo B o un cambio de célula Intra Nodo B. Será comprendido por aquellos expertos en la técnica que existen muchos aspectos para la capa MAC, incluyendo la capa MAC-hs y la capa MAC-d. Para simplificar la descripción de la presente invención, se hará referencia aquí posteriormente de manera general a la capa MAC. El HS-DSCH es un canal de transporte de datos. Por cada canal de transporte de datos, puede existir una pluralidad de instancias de RLC. Las instancias de RLC son esencialmente canales lógicos los cuales pueden ser trazados hacia el mismo canal de transporte; por ejemplo, varias entidades RLC pueden ser trazadas a un solo canal de transporte HS-DSCH. Una instancia de RLC es llamada Modo Reconocido (AM) si se usa ARQ para asegurar la transmisión 13 correcta entre instancias RLC semejantes. Un par de entidades de RLC de AM usan un PDU de estado para el receptor parta indicar al emisor que el estado de transmisiones exitosas de PDU. Después de la ocurrencia del cambio de célula de HS-DSCH y un reajuste de la capa MAC como cada una de las instancias RLC de AM asociadas con un HS-DSCH particular genera una PDU de estado. El mensaje RRC junto con el indicador de reajuste de la capa MAC es recibido y procesado por el RRC en el UE (paso 18) . El RRC de la UE verifica si se estableció un indicador de reajuste de la capa MAC, y si es así el RRC informa a la capa MAC de la petición de reajuste de la capa MAC (paso 20) . Tras la recepción de la petición de reajuste de la capa MAC, la capa MAC se reajusta y además de otras tareas limpia todas las PDU almacenadas en sus memorias intermedias de reordenamiento a las RLC trazadas hacia el HS-DSCH (paso 22) . Todas las PDU limpiadas son entonces procesadas por las instancias RLC trazadas a HS-DSCH (paso 24) antes de la generación de un reporte de estado de PDU (paso 26) . El procesamiento de RLC del PDU detenido en las memorias intermedias de reordenamiento antes de la generación de un reporte de estado de PDU es necesario para proporcionar un estado de transmisión completo y exacto al R C. Si los reportes de estado de PDU son generados 14 inicialmente (es decir antes de que todas las PDU almacenadas temporalmente en las filas de espera de reordenamiento MAC, sean procesadas en las instancias RLC) algunas PDU pueden ser indicadas incorrectamente como no recibidas, y como resultado pueden ser generadas las retransmisiones de PDU innecesarias por el RNC . Existen varias formas de asegurar que todas las PDU hayan sido procesadas por el RLC de modo que las entidades RLC de AM sean capaces de obtener el estado correcto de todas las PDU recibidas exitosamente. Primero, la capa MAC envía PDU en secuencia desde cada fila de espera de reordenamiento y entonces genera una indicación de "fin de PDU" por cada fila de espera de reordenamiento. En una segunda alternativa, la última PDU de cada fila de espera de reordenamiento tiene un indicador especial. Esos son reportes del estado de las RLC de PDU recibidas en el UE. En una tercera alternativa, el RLC confirma a la capa MAC cuando las PDU han sido procesadas, y después del procesamiento de todas las PDU, la capa MAC genera una petición de estado de PDU para el RLC. Deberá comprenderse que existen demasiadas formas de coordinar el procesamiento entre la capa MAC y el RLC para asegurar que todas las PDU sean procesadas por el RLC antes de la generación de un mensaje de estado PDU. 15 Después de recibir y procesar las PDU, el RLC de A genera un recorte de estado de PDU (paso 26) el cual indica todas las PDU recibidas de manera exitosa o no exitosa. El reporte de estado de PDU es generado por cada instancia de RCL de AM trazada al HS-DSCH. Un reporte de estado de PDU puede ser generado aún cuando no fueran enviadas PDU desde la capa MAC para esa instancia de RCL de AM. El UE entonces envía de manera autónoma el reporte de estado del PDU por cada instancia de RCL de AM asociada con HS-DSCH al RNC. En el RNC, asumiendo que las entidades RLC de AM y MAC no sean informadas para detener la transmisión de PDU debido al reajuste de la capa MAC, el RNC continua transmitiendo PDU si importar el reajuste de la capa MAC. Tras la recepción del reporte de estado del PDU por cada instancia de RLC de AM asociada con HS-DSCH, las instancias RLC en el RNC procesan los reportes de estado (paso 28) para determinar las PDU perdidas y generar las retransmisiones de PDU necesarias para asegurar la entrega exitosa (paso 30) . Para lograr la calidad de requerimientos de servicio, las retransmisiones pueden tener precedencia sobre el procesamiento de transmisión actual . Deberá comprenderse que la necesidad del reajuste de la capa MAC es común con la necesidad de generar un reporte de estado de PDU. La indicación de cualquier 16 requerimiento, o alguna indicación común, puede ser señalada al UE para invocar al reajuste de la capa MAC y la generación del reporte de estado de PDU. El UE efectuará entonces cada función en la secuencia descrita. Esta primera modalidad de la presente invención como se muestra en la Figura 2 permite a la RNC seguir transmitiendo a la UE mientras la trayectoria de datos es cambiada de un enlace de radio a otra. Sin embargo de acuerdo con dos modalidades alternativas de la presente invención, mostradas en la Figura 3 y 4, las transmisiones de datos son mantenidas tras un cambio de celda HS-DSCH u otros eventos que dan como resultado la necesidad de dar reajuste a la capa MAC hasta la ocurrencia de un evento posterior. Deberá mostrarse que los pasos mostrados en la Figura 3 y 4 y los mismos números de elemento que en los pasos mostrados en la Figura 2 son idénticos. En consecuencia, la descripción de aquellos pasos no se repetirá cuando se haga referencia a las Figuras 3 y 4. Una segunda modalidad de la presente invención comprende el método 40 para determinar el estado de transmisiones de PDU al UE con retraso mínimo después de una condición de reajuste de la capa MAC y se muestra en la Figura 3. Después de que el RNC reconoce la necesidad del reajuste de la capa MAC (paso 12) y el Nodo B y el UE son identificados (pasos 14 y 16) , el RNC detiene las 17 transmisiones del HS-DSCH (paso 17) de enlace descendente. Nótese que el paso 17 puede ocurrir antes del paso 14 o 16 sin ninguna consecuencia adversa. El NRC recibe posteriormente el reporte de estado de PDU (paso 32). El reporte de estado de PDU indica la pérdida de PDU como resultado del reajuste de MAC y la pérdida potencialmente del PDU en el Nodo B de origen en el caso de un cambio de célula de HS-DSCH. El reporte de estado de PDU es entonces procesado (paso 34) y las PDU perdidas son retransmitidas al UE (paso 36) . El RNC inicia la transmisión en la nueva célula programando una transmisión de las PDU pérdidas que requiere retransmisión primero. El RNC reasume entonces las transmisiones de PDU (paso 38) en el punto donde las transmisiones fueron detenidas previamente en el paso 17. Nótese que también es posible que los pasos 36 y 38 se efectúen simultáneamente. Refiriéndose a la Figura 4, en ella se muestra una tercera modalidad de un método 50 de acuerdo con la presente invención. Este método 50 es similar al método 40 mostrado en la Figura 3. Sin embargo, en lugar de reiniciar las transmisiones del HS-DSCH por enlace descendente al UE en respuesta a la recepción de un reporte de estado de PDU en el paso 32 como se muestra en la Figura 3, el método 50 de esta modalidad de la presente invención reinicia las transmisiones tras la recepción de un "activador", o un 18 evento predeterminado (paso 19) . En un primer ejemplo, el activador puede comprender el establecimiento del canal de transporte en la UTRA la cual, como será comprendido por aquellos expertos en la técnica, es logrado por un RNC con el nuevo procedimiento de señalización del Nodo B "objetivo". La recepción en el RNC de una confirmación generada por el Nodo B es usada como activador. En un segundo ejemplo, el activador puede comprender la recepción o detección en la indicación "en-sinc" . Tras el establecimiento de los recursos dedicados en el Nodo B objetivo, una indicación de "en- sinc" puede ser determinada en el Nodo B cuando los canales físicos asignados sean determinados como disponibles para la transmisión en el Nodo B. La indicación de este evento es cambiada al RNC y puede entonces ser usada como un activador . En un tercer ejemplo, el activador puede comprender la conclusión del procedimiento RRC, (es decir, confirmación de la recepción del RNC de los mensajes de RRC de UE) . El mensaje de RRC señalado en el paso 16 da como resultado un mensaje de confirmación de RRC que es generado por el UE y enviado al RNC. Cuando este mensaje es recibido en el RNC puede ser usado como activador. Deberá notarse que existen muchas señales diferentes que son enviadas entre el UE y el RNC, y 19 cualquiera de esas pueden ser seleccionadas según se desee por el usuario para actuar como el activador de acuerdo con al presente invención. En consecuencia, se pretende que los tres ejemplos mencionados anteriormente sean instructivos más que restrictivos. Sin importar la forma del activador, después de que el activador es recibido el RNC reinicia las transmisiones del HS-DSCH (paso 21) .
