Title (EN) SELECTIVE SYMBOL REPETITION FOR SFBC ON SPDCCH
(FR) RÉPÉTITION SÉLECTIVE DE SYMBOLES POUR SFBC SUR SPDCCH
Abstract:
(EN) When the number of Spatial Block Coded (SBC) modulation symbols in a Physical Resource Block (PRB) is not divided evenly by the number of SBC antenna ports, an SBC coded modulation symbol of a group of SBC coded modulation symbols is repeated, where the same Resource Element (RE) location is repeated on all antennas. In some embodiments, the repeated symbol is adjacent to a modulation symbol of the group that is not repeated. In other embodiments, the repeated modulation symbol is in an adjacent subcarrier to the subcarrier that carries the modulation symbol that is repeated. RE groups with relatively larger numbers of non- zero modulation symbols on a given antenna port and PRB occupy different antenna ports in different PRBs.
(FR) Selon l'invention, lorsque le nombre de symboles de modulation codés par blocs spatiaux (SBC) dans un bloc de ressources physiques (PRB) n'est pas divisé uniformément par le nombre de ports d'antenne SBC, un symbole de modulation codé par SBC d'un groupe de symboles de modulation codés par SBC est répété, le même emplacement d'élément de ressource (RE) étant répété sur toutes les antennes. Dans certains modes de réalisation, le symbole répété est adjacent à un symbole de modulation du groupe qui n'est pas répété. Dans d'autres modes de réalisation, le symbole de modulation répété est dans une sous-porteuse adjacente à la sous-porteuse qui transporte le symbole de modulation qui est répété. Des groupes de RE ayant des nombres relativement plus grands de symboles de modulation non nuls sur un port d'antenne donné et un PRB occupent différents ports d'antenne dans différents PRB.
