Title
(EN) METHOD AND APPARATUS FOR TRANSMITTING REFERENCE SIGNALS IN COMMUNICATION SYSTEMS
(FR) PROCÉDÉ ET APPAREIL POUR TRANSMETTRE DES SIGNAUX DE RÉFÉRENCE DANS DES SYSTÈMES DE COMMUNICATION
Abstract
(EN)
Methods and apparatus are described for a Relay Node (RN) that is transparent to User Equipments to transmit, together with a base station (Node B), Reference Signals (RS) to UEs, to receive RS from UEs, to perform transmissions of Transport Blocks (TBs) to the Node B or to UEs and receptions of TBs from the Node B or from UEs, where the transmissions of TBs from the RN are for retransmissions associated with a Hybrid Automatic Repeat reQuest (HARQ) process for the same TBs, and enabling the Node B to obtain control information signaled from UEs while signaling from the RN interferers with that signaling of control information.
(FR)
L'invention concerne des procédés et un appareil pour un nœud de relais (RN) qui est transparent à des équipements d'utilisateur pour transmettre, en même temps qu'une station de base (nœud B), des signaux de référence (RS) aux UE, recevoir les RS provenant des UE, réaliser les transmissions des blocs de transport (TB) vers le nœud B ou les UE et les réceptions des TB provenant du nœud B ou des UE, les transmissions des TB provenant du RN étant destinées aux retransmissions associées avec un processus de demande de répétition automatique hybride (HARQ) pour les mêmes TB, et permettant au nœud B d'obtenir des informations de commande signalées depuis les UE tandis que la signalisation provenant du RN interfère avec cette signalisation des informations de commande.
