Title (EN) HIERARCHICAL BROADCAST SERVICE WITH BLIND RETRANSMISSION
(FR) SERVICE DE DIFFUSION HIÉRARCHIQUE AVEC RETRANSMISSION AVEUGLE
Abstract: front page image
(EN)In a broadcast service area having regions with varying inter site distances between transmitter sites, the robustness of the transmitted signal is set to meet minimum quality of service (QoS) requirements in the region having small ISD, and additional resources are allocated to the region having large ISD to provide greater robustness. The additional resources in the large ISD area may be used for blind retransmissions of either the original data or new data.
(FR)Dans une zone de service de diffusion ayant des régions avec des distances inter-site variables entre des sites de transmission, la force du signal transmis est définie de sorte à répondre à des exigences de qualité de service (QoS) minimum dans la région ayant une courte ISD tandis que des ressources supplémentaires sont allouées à la région ayant une longue ISD, ce qui permet d'augmenter ainsi la force du signal transmis. Les ressources supplémentaires dans la région de longue ISD peuvent être employées pour accomplir des retransmissions aveugles de données originales ou de nouvelles données.
