Title
(EN) TRANSMISSION OF SYNCHRONIZATION SIGNALS
(FR) TRANSMISSION DE SIGNAUX DE SYNCHRONISATION
Abstract
(EN)
There is provided mechanisms for transmission of synchronization signals. A method is performed by a network node. The method comprises transmitting polarized bursts of SSB in beams. One SSB is transmitted per each beam in each burst. Polarization of at least one of the SSBs changes between two consecutive bursts of the SSBs.
(FR)
La présente invention concerne des mécanismes pour la transmission de signaux de synchronisation. Un procédé est réalisé par un nœud de réseau. Le procédé comprend la transmission de rafales polarisées de SSB dans des faisceaux. Un SSB est transmis pour chaque faisceau dans chaque rafale. La polarisation d'au moins un des SSB change entre deux rafales consécutives des SSB.
