Abstract
(EN)
Provided are a method and an apparatus for mapping a synchronization signal on a relay link in the present invention. By generating a synchronization sequence, and by determining the mapping positions, in the frequency direction and the time direction, of the synchronization signal, the mapping mode of the synchronization signal on a backhaul link between a Base Station(BS) and a Relay Node(RN) is implemented. The method in the present invention can be well adapted to a backhaul link between a BS and a RN and the mapping mode of the synchronization signal is simple, thus not only guaranteeing backward compatibility(compatible with a Long Term Evolution(LTE) system), but also solving the problem how the RN can correctly receive a Primary Synchronization Signal(PSS) and a Secondary Synchronization Signal(SSS) transmitted by the BS, only with a need of low cost, while guaranteeing that the RN can normally finish the tracking work.

L'invention concerne un procédé et un appareil permettant de mapper un signal de synchronisation sur une liaison de relais. En générant une séquence de synchronisation, et en déterminant les positions de mappage, dans la direction de fréquence et la direction temporelle, du signal de synchronisation, on met en oeuvre le mode de mappage du signal de synchronisation sur une liaison terrestre entre une station de base (BS) et un noeud de relais (RN). Le procédé selon l'invention peut parfaitement être adapté à une liaison terrestre entre une BS et un RN et le mode de mappage du signal de synchronisation est simple, ce qui non seulement garantit une rétrocompatibilité (soit compatible avec un système à évolution à long terme (LTE)),mais également permet de résoudre le problème, à savoir comment le RN peut correctement recevoir un signal de synchronisation primaire (PSS) et un signal de synchronisation secondaire (SSS) émis par la BS, dont le coût est bas, mais qui garantit que le RN peut normalement achever le suivi du travail.
