Title (EN) METHOD AND APPARATUS FOR TRANSMITTING AN OUTPUT STREAM OF SYMBOLS OVER AN ANTENNA PORT
(FR) PROCÉDÉ ET APPAREIL DE TRANSMISSION D'UN FLUX DE SORTIE DE SYMBOLES SUR UN PORT D'ANTENNE
Abstract:
(EN) A method (900) and apparatus (1000) transmit an output stream of symbols over an antenna port. Data can be encoded (910) to generate encoded data at a transmitter at a base station. At least two streams of modulated symbols can be generated (920) at the base station from the encoded data. Each of the at least two streams of modulated symbols can correspond to an antenna port of a plurality of antenna ports at the base station. A non-empty subset of the at least two streams of the modulated symbols can be selected (930) at the base station. The selected subset of the at least two streams of symbols can be transmitted (950) from the base station over an antenna port implemented by applying a weighting to a plurality of antennas.
(FR) Un procédé (900) et un appareil (1000) transmettent un flux de sortie de symboles sur un port d'antenne. Le procédé peut comprendre les étapes consistant à : au niveau d'une station de base, coder (910) des données de façon à générer des données codées au niveau d'un émetteur ; au niveau de la station de base, générer (920) au moins deux flux de symboles modulés à partir des données codées, chacun desdits au moins deux flux de symboles modulés pouvant correspondre à un port d'antenne parmi une pluralité de ports d'antenne au niveau de la station de base ; au niveau de la station de base, sélectionner (930) un sous-ensemble non vide desdits au moins deux flux de symboles modulés ; et transmettre (950) le sous-ensemble sélectionné desdits au moins deux flux de symboles à partir de la station de base sur un port d'antenne utilisé en appliquant une pondération à une pluralité d'antennes.
