Title (EN) ANTENNA TIME OFFSET IN MULTIPLE-INPUT-MULTIPLE-OUTPUT AND COORDINATED MULTIPOINT TRANSMISSIONS
(FR) DÉCALAGE TEMPOREL ENTRE DES ANTENNES DANS DES TRANSMISSIONS MULTIPLES ENTRÉES MULTIPLES SORTIES ET DES TRANSMISSIONS MULTIPOINTS COORDONNÉES
Abstract: front page image
(EN)A method (800) for wireless communication is provided which includes receiving first and second signals transmitted from first and second antennas, respectively, (802) determining a time offset between the first and second antennas based on the first and second signals (804), and reporting information regarding the time offset, including information regarding the time offset as being above or below a predetermined threshold (806). Another method (900) for wireless communication is provided which includes generating channel state information feedback based on an assumption that the time offset is being compensated at a transmitter side. Yet another method (1000) for wireless communication is provided which includes receiving information regarding a time offset between multiple transmit antennas, including information regarding the time offset as being above or below a predetermined threshold (1002), and adapting downlink transmissions to account for the time offset (1004).
(FR)La présente invention concerne un procédé de communication sans fil qui consiste à recevoir des premier et second signaux émis respectivement par des première et seconde antennes ; déterminer un décalage temporel entre les première et seconde antennes sur la base des premier et second signaux ; et signaler des informations concernant le décalage temporel, comportant des informations précisant si le décalage temporel est au-dessus ou en dessous d'un seuil prédéterminé. Un autre procédé de communication sans fil de la présente invention consiste à générer une réponse d'informations d'état de canal sur la base d'une supposition que le décalage temporel est compensé au niveau de l'émetteur. Encore un autre procédé de communication sans fil de la présente invention consiste à recevoir des informations concernant un décalage temporel entre de multiples antennes d'émission, comportant des informations précisant que le décalage temporel est au-dessus ou en dessous d'un seuil prédéterminé, et à adapter des transmissions en liaison descendante pour tenir compte du décalage temporel.
