Title
(EN) SYSTEMS AND METHODS FOR INTER RELAY INTERFERENCE COORDINATION
(FR) SYSTÈMES ET PROCÉDÉS DE COORDINATION D'INTERFÉRENCES INTERRELAIS
Abstract
(EN) A method for inter relay interference coordination (IRIC) by a first relay node in a wireless communications system is described. A second relay node is communicated with over a relay interface. A first set of user equipment (UE) communication settings is received over the relay interface that corresponds to the second relay node. A second set of UE communication settings is determined that corresponds to the first relay node. The second set of UE communication settings is based on the first set of UE communication settings.
(FR) Cette invention se rapporte à un procédé de coordination d'interférences interrelais (IRIC) par un premier nœud de relais dans un système de communications sans fil. Un deuxième nœud de relais est mis en communication par l'intermédiaire d'une interface de relais. Un premier ensemble de réglages de communication d'un équipement utilisateur (UE) est reçu par l'intermédiaire de l'interface de relais qui correspond au deuxième nœud de relais. On détermine un deuxième ensemble de réglages de communication d'UE qui correspond au premier nœud de relais. Le deuxième ensemble de réglages de communication d'UE est basé sur le premier ensemble de réglages de communication d'UE.
