Abstract:
(EN) The present invention improves throughput in such a propagation path environment that retransmission is repeated. In a transmission-side wireless communication device, transmission signal storage memories 102-1, 102-2 hold bit sequences related to two packet signals for which NACK has been returned, a helper packet generation unit 103 operates the exclusive OR of bit sequences related to two or more predetermined number of packet signals held in the transmission signal storage memories, and a coding unit 101-2 to a transmitting and receiving antenna 107-1 transmit an auxiliary packet generated by coding a bit sequence of a helper packet that is a result of the exclusive OR operation when the number of packet signals for which NACK has been returned reaches the predetermined number.
(FR) La présente invention améliore le débit dans un environnement de trajet de propagation dans lequel la retransmission est répétée. Dans un dispositif de communication sans fil du côté émission, des mémoires de stockage de signal de transmission (102-1, 102-2) conservent des séquences de bits concernant deux signaux de paquet pour lesquels un NACK a été renvoyé, une unité de production de paquets d'aide (103) effectue une opération OU exclusif de séquences de bits concernant un certain nombre prédéterminé (deux ou plus) de signaux de paquet conservés dans les mémoires de stockage de signal de transmission, et une unité de codage (101-2) associée à une antenne de transmission et de réception (107-1) transmet un paquet auxiliaire produit en codant une séquence de bits d'un paquet d'aide qui est le résultat d'une opération OU exclusif lorsque le nombre de signaux de paquet pour lesquels un NACK a été renvoyé atteint le nombre prédéterminé.
(JA) 再送が繰り返されるような伝搬路環境においてスループットを改善する。 送信側の無線通信装置において、送信信号格納メモリ102-1,102-2が、NACKが返送された2個のパケット信号に係るビット系列を保持し、ヘルパーパケット生成部103が、送信信号格納メモリに保持された2以上の所定数のパケット信号に係るビット系列について排他的論理和を演算し、符号化部101-2~送受信アンテナ107-1が、NACKが返送されたパケット信号の数が所定数となった場合に、排他的論理和演算の結果であるヘルパーパケットのビット系列を符号化して生成した補助的なパケット信号を送信する。
