Title (EN) METHOD FOR RELAYING DATA PERFORMED BY A RELAY STATION IN WIRELESS COMMUNICATION SYSTEM BASED ON TDD
(FR) PROCÉDÉ POUR RELAYER DES DONNÉES GRÂCE À UNE STATION RELAIS DANS UN SYSTÈME DE COMMUNICATION SANS FIL SUR LA BASE D'UN TDD
Abstract:
(EN) A method of relaying data performed by a relay station in a wireless communication system based on time division duplex (TDD) is provided. The relay station receives downlink data from a base station and relays the downlink data to at least one mobile station in an uplink subframe which belongs to an unlinked subframe. Accordingly, uplink acknowledgement (ACK) collision can be avoided, and efficiency of resource allocation can be increased.
(FR) L'invention concerne un procédé de relais de données effectué par une station relais dans un système de communication sans fil sur la base d'un duplexage par répartition dans le temps (TDD). La station relais reçoit des données en liaison descendante d'une station de base et relaie les données en liaison descendante vers au moins une station mobile dans une sous-trame en liaison montante qui appartient à une sous-trame non liée. En conséquence, une collision d'accusé de réception (ACK) en liaison montante peut être évitée, et l'efficacité de l'attribution de ressource peut être accrue.
