Title (EN) APPARATUSES, METHODS AND COMPUTER PROGRAMS FOR DETERMINING TRANSMISSION CONTROL INFORMATION
(FR) APPAREILS, PROCÉDÉS ET PROGRAMMES D’ORDINATEUR POUR DÉTERMINER DES INFORMATIONS DE COMMANDE DE TRANSMISSION
Abstract:
(EN) Embodiments relate to apparatuses (10; 20), methods and computer programs for determining transmission control information. The Apparatus (10) is suitable for a base band unit (110) of a base station transceiver (100) of a mobile communication system (300), the base station transceiver (100) further comprising one or more radio units (120) configured to wirelessly communicate with the base band unit (110) using one or more wireless fronthaul links. The apparatus (10) comprises at least one output (12) configured to transmit a downlink component of the one or more wireless fronthaul links to the one or more radio units (120). The apparatus (10) further comprises at least one input (14) configured to receive an uplink component of the one or more wireless fronthaul links from the one or more radio units (120). The apparatus (10) further comprises a control module (16) configured to control the at least one output (12) and the at least one input (14). The control module (16) is further configured to transmit a reference signal via the at least one output (12) to the one or more radio units (120). The control module (16) is further configured to receive a loopback version of the reference signal via the at least one input (14) from the one or more radio units (120). The control module (16) is further configured to determine transmission control information based on an attenuation of the reference signal determined based on the loopback version of the reference signal. The transmission control information comprises information related to a per-radio unit transmission power to be used by the one or more radio units (120) for transmissions on the one or more wireless fronthaul links. The control module (16) is further configured to provide the transmission control information to the one or more radio units (120) via the at least one output (12).
(FR) Conformément à des modes de réalisation, l’invention concerne des appareils (10 ; 20), des procédés et des programmes d’ordinateur pour déterminer des informations de commande de transmission. L’appareil (10) est approprié pour une unité de bande de base (110) d’un émetteur-récepteur de station de base (100) d’un système de communication mobile (300), l’émetteur-récepteur de station de base (100) comprenant en outre une ou plusieurs unités radio (120) configurées pour communiquer sans fil avec l’unité de bande de base (110) à l’aide d’une ou plusieurs liaisons de raccordement aux sites cellulaires sans fil. L’appareil (10) comprend au moins une sortie (12) configurée pour transmettre une composante de liaison descendante de ladite liaison de raccordement aux sites cellulaires sans fil à ladite unité radio (120). L’appareil (10) comprend en outre au moins une entrée (14) configurée pour recevoir une composante de liaison montante de ladite liaison de raccordement aux sites cellulaires sans fil à partir de ladite unité radio (120). L’appareil (10) comprend en outre un module de commande (16) configuré pour commander ladite sortie (12) et ladite entrée (14). Le module de commande (16) est en outre configuré pour transmettre un signal de référence par l’intermédiaire de ladite sortie (12) à ladite unité radio (120). Le module de commande (16) est en outre configuré pour recevoir une version d’essai de rebouclage du signal de référence par l’intermédiaire de ladite entrée (14) à partir de ladite unité radio (120). Le module de commande (16) est en outre configuré pour déterminer des informations de commande d’émission sur la base d’une atténuation du signal de référence déterminé sur la base d’une version d’essai de rebouclage du signal de référence. Les informations de commande de transmission comprennent des informations associées à une puissance de transmission par unité radio devant être utilisées par ladite unité radio (120) pour unetransmission sur ladite liaison de raccordement aux sites cellulaires sans fil. Le module de commande (16) est en outre configuré pour fournir les informations de commande de transmission à ladite unité radio (120) par l’intermédiaire de ladite sortie (12).
