Abstract
(EN)
In one embodiment, a method for wireless communication includes transmitting first system information for a subframe structure from a controller to a relay node. The first system information includes radio resource configuration for a downlink backhaul link. The subframe structure includes a physical downlink control channel (PDCCH) region for user equipments and a separate relay physical downlink control channel (R-PDCCH) region for relay nodes.

Dans un mode de réalisation, l'invention porte sur un procédé de communication sans fil comprenant la transmission de premières informations de système pour une structure de sous-trame, d'un dispositif de commande à un nœud de relais. Les premières informations de système comprennent une configuration de ressources radio pour une liaison terrestre de liaison descendante. La structure de sous-trame comprend une région de canal de commande de liaison descendante physique (PDCCH) pour des équipements utilisateurs et une région de canal de commande de liaison descendante physique de relais séparé (R-PDCCH) pour des nœuds de relais.
