Abstract
(EN)
A method and an apparatus for mapping and allocating resources for Relay link-Physical Downlink Shared CHannel (R-PDSCH) are disclosed by the present invention, wherein the method includes that: when resources allocated for Relay link-Physical Downlink Control CHannel (R-PDCCH) and R-PDSCH overlap, data of said R-PDSCH is not mapped and sent on overlapped resources of the allocated resources, or the data of said R-PDSCH to be sent on the allocated overlapped resources is punched; data of said R-PDSCH is mapped and sent on all or partial resources which are not occupied by the R-PDCCH on the allocated resources; a receiving terminal receives data according to the R-PDSCH mapping method; wherein, the R-PDSCH resource allocation includes that: the R-PDSCH reuses a resource allocation mode corresponding to the shared channel in an LTE system, or uses a group tree resource allocation mode. The present invention well applies a link between a base station and a relay node, the resource allocation mode is flexible, and the signaling overhead is low. Backward compatibility is ensured, as well as the problem of mapping and allocating resources for the R-PDSCH is solved.

La présente invention se rapporte à un procédé et à un appareil pour le mappage et l'allocation de ressources à un canal physique partagé sur la liaison descendante de la liaison relais (R-PDSCH). Le procédé selon l'invention comprend les étapes suivantes : lorsque des ressources allouées à un canal de contrôle physique sur la liaison descendante de la liaison relais (R-PDCCH) et à un R-PDSCH font double emploi, des données dudit R-PDSCH ne sont pas mappées ni envoyées sur les ressources des ressources allouées qui font double emploi, ou bien les données dudit R-PDSCH devant être envoyées sur les ressources allouées qui font double emploi sont supprimées; des données dudit R-PDSCH sont mappées et envoyées sur une partie ou sur la totalité des ressources qui ne sont pas occupées par le R-PDCCH parmi les ressources allouées; un terminal de réception reçoit des données conformément au procédé de mappage de R-PDSCH. Selon l'invention, l'allocation de ressources R-PDSCH comprend les étapes suivantes : le R-PDSCH réutilise un mode d'allocation de ressources correspondant au canal partagé dans un système LTE, ou bien il utilise un mode d'allocation de ressources du type à arborescence de groupe. La présente invention s'applique parfaitement à une liaison entre une station de base et un nœud relais, le mode d'allocation de ressources est flexible, et le surdébit de signalisation est faible. La rétrocompatibilité était garantie, et le problème de mappage et d'allocation de ressources au R-PDSCH est résolu.
