Abstract:
(EN) A reduction in the efficiency of utilizing wireless resources due to misdetection of a response signal that notifies a receiving result is suppressed. A wireless communication method used in a wireless communication system (10) having a first wireless device (11) and a second wireless device (12) is provided, wherein the first wireless device (11) receives a first wireless signal (21) composed of a plurality of portions and transmits first information (22) that indicates a receiving result with respect to each of the plurality of portions, the second wireless device (12) transmits a second wireless signal (23) including at least one portion that corresponds to a reception failure indicated in the first information (22) and transmits second information (24) that indicates which portion of the plurality of portions is included in the second wireless signal (23), and the first wireless device (11) transmits third information (25) that indicates the result of comparison between the first information (22) and the second information (24).
(FR) La présente invention permet de supprimer la réduction de l'efficacité d'utilisation de ressources sans fil due à une mauvaise détection d'un signal de réponse qui notifie un résultat de réception. La présente invention concerne en outre un procédé de communication sans fil utilisé dans un système de communication sans fil (10) comprenant un premier dispositif sans fil (11) et un second dispositif sans fil (12). Le premier dispositif sans fil (11) reçoit un premier signal sans fil (21) composé d'une pluralité de parties et transmet des premières informations (22) indiquant un résultat de réception par rapport à chaque partie d'une pluralité de parties, le second dispositif sans fil (12) transmet un second signal sans fil (23) comprenant au moins une partie qui correspond à une défaillance de réception indiquée dans les premières informations (22) et transmet des deuxièmes informations (24) qui indiquent quelle partie de la pluralité de parties est incluse dans le second signal sans fil (23), et le premier dispositif sans fil (11) transmet des troisièmes informations (25) qui indiquent le résultat de la comparaison entre les premières informations (22) et les deuxièmes informations (24).
(JA) 受信結果を通知する応答信号の誤検出に伴う無線リソースの利用効率低下を抑制すること。 第1の無線装置(11)及び第2の無線装置(12)を有する無線通信システム(10)で用いる無線通信方法であって、第1の無線装置(11)が、複数の部分で構成される第1の無線信号(21)を受信し、複数の部分それぞれについての受信結果を示す第1の情報(22)を送信し、第2の無線装置(12)が、第1の情報(22)で示される受信失敗に対応する少なくとも1つの部分を含む第2の無線信号(23)を送信し、複数の部分のうちのどの部分が第2の無線信号(23)の中に含まれているかを示す第2の情報(24)を送信し、第1の無線装置(11)が、第1の情報(22)と第2の情報(24)との比較結果を示す第3の情報(25)を送信する、無線通信方法が提供される。
