METHOD AND APPARATUS FOR CONTROL AND DATA MULTIPLEXING IN A MIMO COMMUNICATION SYSTEM
(FR)
PROCÉDÉ ET APPAREIL DESTINÉS À LA COMMANDE ET AU MULTIPLEXAGE DE DONNÉES DANS UN SYSTÈME DE COMMUNICATION MIMO
Abstract:
(EN)
Systems and methodologies are described herein that facilitate control and data multiplexing for uplink (UL) multiple-input-multiple-output (MIMO) communication within a wireless communication system. As described herein, a device conducting uplink MIMO communication in a wireless communication system can multiplex control signaling and data across one or more of a plurality of layers (e.g., corresponding to spatial layers, codewords, etc.) associated with an uplink transmission. Techniques are described herein for selecting layers of a transmission on which to schedule control signaling and selecting offsets to apply to the control signaling scheduled on selected layers. Further, techniques are described herein for leveraging a multi-layer transmission to increase the efficiency of acknowledgement communication. In addition, techniques are described for selecting a modulation and coding scheme (MCS) to apply to control signaling that is combined with data in an uplink multi-layer transmission.
(FR)
La présente invention concerne des systèmes et des méthodologies qui facilitent la commande et le multiplexage de données pour une communication à entrée multiple sortie multiple (MIMO) en liaison montante (UL) dans un système de communication sans fil. Comme décrit par la présente, un dispositif dirigeant une communication MIMO en liaison montante dans un système de communication sans fil peut multiplexer une signalisation de commande et des données sur une ou plusieurs couches d'une pluralité de couches (par ex., correspondant à des couches spatiales, des mots codés, etc.) associées à une transmission en liaison montante. Des techniques sont décrites dans la présente servant à sélectionner des couches d'une transmission sur laquelle programmer une signalisation de commande et sélectionner des décalages à appliquer à la signalisation de commande programmée sur les couches sélectionnées. En outre, des techniques sont décrites dans la présente, ces techniques servant à s'appuyer sur une transmission multicouche pour augmenter l'efficacité d'une communication avec accusé de réception. De plus, des techniques sont décrites pour sélectionner un procédé de codage et de modulation (MCS) afin d'appliquer une signalisation de commande qui est combinée aux données dans une transmission multicouche en liaison montante.
