Abstract
(EN)
A retransmitting method, a radio receiving apparatus and a multiantenna communication system that are capable of improving the system throughput. According to this method, the receiving apparatus determines whether a received substream has an error and hence a retransmittal is necessary (401); calculates a signal-to-interference noise ratio after detection of multiinput/multioutput of the substream that must be retransmitted (402); compares the signal-to-interference noise ratio of the substream, which must be retransmitted, with a predetermined threshold value (403); performs a full retransmission of the substream, which must be retransmitted, when the signal-to-interference noise ratio of the substream, which must be retransmitted, is smaller than the predetermined threshold value (404); and performs a redundant-increased retransmission of the substream, which must be retransmitted, when the signal-to-interference noise ratio of the substream, which must be retransmitted, is greater than the predetermined threshold value (405,406,407).

Procédé de retransmission, appareil récepteur de radio et système multi-antenne de communication radio, capables d'améliorer le débit du système. D'après le présent procédé, l'appareil récepteur détermine si un sous-flux reçu contient une erreur et nécessite de ce fait une retransmission (401); calcule un rapport signal-bruit d'interférence après la détection d'entrées/sorties multiples du sous-flux dont la retransmission est nécessaire (402); compare le rapport signal-bruit d'interférence du sous-flux à retransmettre à une valeur de seuil prédéterminée (403); effectue une retransmission complète du sous-flux à retransmettre lorsque le rapport signal-bruit d'interférence du sous-flux à retransmettre est inférieur à la valeur de seuil prédéterminée (404); et effectue une retransmission à redondance renforcée du sous-flux à retransmettre lorsque le rapport signal-bruit d'interférence du sous-flux à retransmettre est supérieur à la valeur de seuil prédéterminée (405,406,407).

 本発明はシステムのスループットを向上することができる再送方法、無線受信装置、およびマルチアンテナ通信システムを開示する。この方法において、受信装置は受信したサブストリームに誤りがあって再送する必要があるか否かを検出し(401)、上記の再送が必要なサブストリームのマルチインプット・マルチアウトプット検出後の信号対干渉雑音比を算出し(402)、上記の再送が必要なサブストリームの信号対干渉雑音比と所定の閾値とを比較し(403)、上記の再送が必要なサブストリームの信号対干渉雑音比が所定の閾値より低い場合は上記再送が必要なサブストリームに対して全部再送を行い(404)、上記の再送が必要なサブストリームの信号対干渉雑音比が所定の閾値より高い場合は再送が必要なサブストリームに対して冗長増加再送を行う(405、406、407)。
