Abstract

Un sistema (66) y método (83,90) de mensajería de Respuesta de Acceso Aleatorio, RAR, cuando una estación (72) base emplea formación de haces estrechos. Múltiples mensajes de RAR se transmiten sucesivamente desde la estación base hasta un equipo (68) de usuario, UE, antes de que se reciba cualquier respuesta a un mensaje de RAR del UE. De esta manera, a pesar de cualquier discrepancia de calibración entre los haces de Enlace Ascendente, UL, y Enlace Descendente, DL, en el sistema formado por haces, un mensaje de RAR no solo se recibe por el UE, si no que se recibe a través de haz de DL más adecuado para ese UE. Cada mensaje de RAR puede contener un indicador de retraso de programación específico de mensaje en la concesión de UL transportada en el mensaje de RAR para proporcionar un retraso de tiempo ajustable para la transmisión de enlace ascendente del UE programada por la concesión de UL. Múltiples transmisiones de RAR pueden programar una sola transmisión de UL en una instancia de tiempo específica o diferentes transmisiones de UL a diferentes intervalos de tiempo. El UE puede informar a la estación base sobre la mejor transmisión de RAR de DL detectada por el UE.
