Abstract
(EN)
Disclosed are a method and system for processing backhaul link ACK/NACK information. The method includes: determining by an RN a processing mode and a PUCCH format for sending backhaul link uplink ACK/NACK information to the network side according to the backhaul link information and/or configuration indication at the network side; configuring by the network side one or more Un PUCCH resources for a relay node according to the backhaul link information and/or the processing mode and/or PUCCH format of the backhaul link uplink ACK/NACK information; processing by the relay node the backhaul link uplink ACK/NACK information to be sent using the processing mode and the PUCCH format, and sending the processed backhaul link uplink ACK/NACK information to the network side using the configured Un PUCCH resources. The present invention achieves the effect of using the backhaul link to send ACK/NACK information.

La présente invention concerne un procédé et un système de traitement d'informations ACK/NACK de liaison de raccordement. Le procédé consiste à : déterminer par un nœud relais (RN) un mode de traitement et un format PUCCH pour envoyer des informations ACK/NACK de liaison montante de liaison de raccordement au côté réseau en fonction des informations de liaison de raccordement et/ou d'une indication de configuration au niveau du côté réseau ; configurer par le côté réseau une ou plusieurs ressources Un PUCCH pour un nœud relais selon les informations de liaison de raccordement et/ou le mode de traitement et/ou le format PUCCH des informations ACK/NACK de liaison montante de liaison de raccordement ; traiter par le nœud relais les informations ACK/NACK de liaison montante de liaison de raccordement devant être envoyées en utilisant le mode de traitement et le format PUCCH, et envoyer les informations ACK/NACK de liaison montante de liaison de raccordement traitées au côté réseau en utilisant les ressources Un PUCCH configurées. La présente invention permet ainsi d'utiliser la liaison de raccordement pour envoyer des informations ACK/NACK.
