Title (EN) DUAL MODE COMMUNICATIONS DEVICE WITH NULL STEERING AND METHODS FOR USE THEREWITH
(FR) DISPOSITIF DE COMMUNICATION BIMODE AVEC ORIENTATION À ZÉRO ET PROCÉDÉS À UTILISER AVEC CELUI-CI
Abstract:
(EN) In accordance with one or more embodiments, a communication device includes a dual-band antenna array configured to transmit first radio frequency (RF) signals to a remote device in an RF band and to transmit first millimeter wave (MMW) signals to the remote device in a MMW frequency band, wherein the MMW frequency band is above the RF band. A base transceiver station is configured to generate a consolidated steering matrix in accordance with the transmission of the first RF signals to the remote device in the RF band. A remote radio head is configured to convert the consolidated steering matrix to a converted steering matrix that facilitates the transmission of the first MMW signals to the remote device in the MMW frequency band via the dual-band antenna array in accordance with an antenna beam pattern having at least one selected null direction, and further configured to generate the first MMW signals in accordance with the converted steering matrix.
(FR) Selon un ou plusieurs modes de réalisation de l'invention, un dispositif de communication comprend un réseau d'antennes à double bande configuré pour émettre des premiers signaux à radiofréquence (RF) vers un dispositif distant dans une bande RF et pour émettre des premiers signaux à ondes millimétriques (MMW) au dispositif distant dans une bande de fréquences MMW, la bande de fréquences MMW étant au-dessus de la bande RF. Une station d'émetteur-récepteur de base est configurée pour générer une matrice d'orientation consolidée en fonction de l'émission des premiers signaux RF vers le dispositif distant dans la bande RF. Une tête radio distante est configurée pour convertir la matrice d'orientation consolidée en une matrice d'orientation convertie qui facilite l'émission des premiers signaux MMW vers le dispositif distant dans la bande de fréquences MMW par le biais du réseau d'antennes à double bande selon un diagramme de faisceau d'antenne ayant au moins une direction nulle sélectionnée, et en plus configuré pour générer les premiers signaux MMW conformément à la matrice d'orientation convertie.
