Title (EN) WIRELESS COMMUNICATION SYSTEM, MOBILE STATION DEVICE, AND BASE STATION DEVICE
(FR) SYSTÈME DE COMMUNICATION SANS FIL, DISPOSITIF DE STATION MOBILE, ET DISPOSITIF DE STATION DE BASE

Abstract: front page image
(EN) Provided is a wireless communication system, a mobile station device, and a base station device which reduce a resource overhead and do not involve a significant change of an LTE specification in an aperiodic SRS transmission. The wireless communication system is constituted of the base station device and the mobile station device that transmits a data signal to the base station device in an SC-FDMA (Single Carrier Frequency Division Multiple Access) system. The wireless communication system transmits a reference signal for channel measurement from the mobile station device to the base station device. The reference signal for the channel measurement is transmitted using a data transmission channel assigned for each mobile station device by the base station device.
(FR) L'invention porte sur un système de communication sans fil, un dispositif de station mobile et un dispositif de station de base réduisant un sur-débit de ressource et ne mettant pas en jeu une modification significative d'une spécification d'évolution à long terme (LTE) dans une transmission SRS apériodique. Le système de communication sans fil est constitué du dispositif de station de base et du dispositif de station mobile transmettant un signal de données au dispositif de station de base dans un système a accès multiple par répartition de la fréquence à porteuse unique (SC-FDMA). Le système de communication sans fil transmet un signal de référence pour une mesure du canal entre le dispositif de station mobile et le dispositif de station de base. Le signal de référence pour la mesure des canaux est transmis à l'aide d'un canal de transmission de données affecté à chaque dispositif de station mobile par le dispositif de station de base.
(JA)  アピリオディックSRSの送信において、リソースオーバーヘッドを低減し、かつ、LTEの仕様から大きな変更を伴わない無線通信システム、移動局装置および基地局装置を提供する。基地局装置と、SC-FDMA(Single Carrier Frequency Division Multiple Access)方式でデータ信号を前記基地局装置に対して送信する移動局装置とから構成され、前記移動局装置から前記基地局装置に対してチャネル測定用の参照信号を送信する無線通信システムであって、前記チャネル測定用の参照信号は、前記基地局装置から前記移動局装置毎に割り当てられるデータ送信用チャネルを用いて送信される。
