Title
(EN) FULL DUPLEX DEVICE-TO-DEVICE COOPERATIVE COMMUNICATION
(FR) COMMUNICATION COOPÉRATIVE DE DISPOSITIF À DISPOSITIF EN DUPLEX INTÉGRAL
Abstract
(EN)
Examples described herein include apparatuses and methods for full duplex device-to-device cooperative communication. Example systems described herein may include self-interference noise calculators. The output of a self-interference noise calculator may be used to compensate for the interference experienced due to signals transmitted by another antenna of the same wireless device or system. In implementing such a self-interference noise calculator, a selected wireless relaying device or wireless destination device may operate in a full-duplex mode, such that relayed messages may be transmitted as well as information from other sources or destinations during a common time period (e.g., symbol, slot, subframe, etc.).
(FR)
Selon certains exemples, l'invention concerne des appareils et des procédés pour une communication coopérative de dispositif à dispositif en duplex intégral. Des systèmes donnés à titre d'exemple peuvent comprendre des calculateurs de bruit à auto-brouillage. La sortie d'un calculateur de bruit à auto-brouillage peut être utilisée pour compenser le brouillage subi par des signaux transmis par une autre antenne du même dispositif ou système sans fil. Dans la mise en oeuvre d'un tel calculateur de bruit à auto-brouillage, un dispositif de relais sans fil sélectionné ou un dispositif de destination sans fil peut fonctionner dans un mode duplex intégral, de sorte que des messages relayés puissent être transmis ainsi que des informations provenant d'autres sources ou destinations pendant une période de temps commune (par exemple, symbole, intervalle, sous-trame, etc.).
