Abstract:
(EN) A first communication device included in a communication system having the first communication device and a second communication device which wirelessly connects with the first communication device and relays communication of the first communication device comprises: a reception unit that receives packets from the second communication device; and a transmission unit that stores reception acknowledgement packets corresponding to the packets in a buffer, enables transmission of at least some of the reception acknowledgement packets stored in the buffer, and enables discarding of the reception acknowledgement packets that are not transmitted in the aforementioned transmission, in accordance with a discarding rate.
(FR) La présente invention concerne un premier dispositif de communication compris dans un système de communication ayant le premier dispositif de communication et un second dispositif de communication qui se connecte sans fil avec le premier dispositif de communication et relaie une communication du premier dispositif de communication qui comprend : une unité de réception qui reçoit des paquets en provenance du second dispositif de communication ; et une unité de transmission qui stocke des paquets d'accusé de réception correspondant aux paquets dans un tampon, permet la transmission d'au moins certains des paquets d'accusé de réception stockés dans le tampon, et permet d'éliminer les paquets d'accusé de réception qui ne sont pas transmis dans la transmission susmentionnée, conformément à un taux d'élimination.
(JA) 第1の通信装置と、前記第1の通信装置と無線接続し、前記第1の通信装置の通信を中継する第2の通信装置を有する通信システムに含まれる前記第1の通信装置であって、前記第2の通信装置からパケットを受信する受信部と、前記パケットに対応する受信確認パケットをバッファに蓄積し、前記バッファに蓄積する受信確認パケットの少なくとも一部を送信できるようにし、前記送信において送信しない受信確認パケットを破棄率に応じて破棄できるようにする送信部と、を有する。
