Title (EN) ADAPTIVE CYCLIC-SHIFT BASED MULTIPLEXING
(FR) MULTIPLEXAGE BASÉ SUR UN DÉCALAGE CYCLIQUE ADAPTATIF
Abstract:
(EN) Aspects of the present disclosure provide techniques for using cyclic-shifts in code division multiplexing to shift transmitted signals (e.g., reference signals, control signals, and/or data) from different antenna ports of the transmitting device. Particularly, for multiple-input multiple-output (MIMO) systems that multiply the capacity of a radio link by using multiple transmit and receive antennas to exploit multipath propagation, aspects of the present disclosure minimize interference at the receiving device by separating the signals from different antenna ports based on the channel impulse response (or delay spread) of each antenna port of the channel. In some examples, the transmitting device may maximize resource utilization by interleaving the reference signals, control signals, and/or data from a plurality of antenna ports while maintaining adequate spacing between each signal.
(FR) La présente invention concerne, dans certains aspects, des techniques visant à utiliser des décalages cycliques dans un multiplexage par répartition en code pour décaler des signaux émis (p. ex. des signaux de référence, des signaux de commande et/ou des données) à partir de ports d'antenne différents du dispositif d'émission. En particulier, pour des systèmes à entrées et sorties multiples (MIMO) qui multiplient la capacité d'une liaison radio en utilisant des antennes d'émission et de réception multiples pour exploiter une propagation par trajets multiples, certains aspects de la présente invention minimisent l'interférence au niveau du dispositif de réception en séparant les signaux provenant de différents ports d'antenne d'après la réponse impulsionnelle de canal (ou l'étalement des temps de propagation) de chaque port d'antenne du canal. Dans certains exemples, le dispositif d'émission peut maximiser l'utilisation des ressources en entrelaçant les signaux de référence, les signaux de commande et/ou les données provenant d'une pluralité de ports d'antenne tout en maintenant un espacement adéquat entre chaque signal.
