Abstract: front page image
(EN)The wireless communication system according to the present invention includes: a first wireless station; and a plurality of second wireless stations for receiving data from the first wireless station, in accordance with a plurality of transmission formats requiring different amounts of feedback information for transmission purposes. In this wireless communication system the first wireless station sets, in a first period, a communication frame, from among a plurality of communication frames, for carrying out transmission of data to the second wireless stations. According to the length of the first period, the individual second wireless stations assess the congestion factor of the plurality of second wireless stations in the first wireless station.
(FR)L'invention concerne un système de communication sans fil comprenant une première station sans fil, et une pluralité de secondes stations sans fil qui reçoivent les données provenant de la première station sans fil, en fonction d'une pluralité de formats de transmissions nécessitant différents volumes d'informations de rétroaction pour la transmission. Dans ce système de communication sans fil, la première station sans fil définit, dans une première période, une trame de communication parmi une pluralité de trames de communication, pour effectuer la transmission de données vers les secondes stations sans fil. En fonction de la longueur de la première période, les différentes secondes stations sans fil évaluent le facteur de congestion de la pluralité de secondes stations sans fil dans la première station sans fil.
(JA) 本実施例における無線通信システムは、第1無線局と、送信のためのフィードバック情報の量が異なる複数の送信方式に従って、第1無線局からデータを受信する複数の第2無線局を含む無線通信システムである。本実施例における無線通信システムにおいては、第1無線局は、複数の通信フレームの中から、第2無線局へのデータ送信を行う通信フレームを第1の周期で設定し、第2無線局の各々は、第1の周期の長さに応じて、第1無線局における複数の第2無線局の混雑度を判定する。
