Title
(EN) COMMUNICATION DEVICE AND METHOD
(FR) DISPOSITIF ET PROCÉDÉ DE COMMUNICATION
Abstract
(EN) A first communication device for communicating with a second communication device over a link that is utilized at the substantially same time and with the substantially same frequency resource by a pair of further communication devices. The first communication device comprises one or more antenna arrays with which beamforming can be performed, a control unit configured to apply beamformers to control beamforming by the one or more antenna arrays, and an interference alignment module configured to determine whether at least one of the beamformers satisfies an interference condition such that a level of interference leaked to the further communication devices by the first communication device is below a defined threshold, and if available, select the at least one beamformer for communicating with the second communication device. The interference condition is based on channel characteristics between the first communication device and at least one of the further communication devices and non-reciprocity mismatch.
(FR) L'invention porte sur un premier dispositif de communication destiné à communiquer avec un second dispositif de communication sur une liaison qui est utilisée sensiblement en même temps et avec sensiblement la même ressource de fréquence par une paire d'autres dispositifs de communication. Le premier dispositif de communication comprend un ou plusieurs réseaux d'antennes avec lesquels une formation de faisceau peut être effectuée, une unité de commande configurée pour appliquer des formateurs de faisceaux pour commander la formation de faisceau par le ou les réseaux d'antennes, et un module d'alignement d'interférence configuré pour déterminer si au moins l'un des formateurs de faisceau satisfait une condition d'interférence de sorte qu'un niveau d'interférence transmis aux autres dispositifs de communication par le premier dispositif de communication est inférieur à un seuil défini, et, le cas échéant, sélectionner le ou les formateur de faisceaux pour communiquer avec le second dispositif de communication. La condition d'interférence est basée sur des caractéristiques de canal entre le premier dispositif de communication et au moins l'un des autres dispositifs de communication et une non-concordance de non-réciprocité.
