Abstract:
(EN) In order to solve problems of retention at the transmission side and delay at the reception side when performing transmission in a communication system such as a radio LAN system, access control is performed so that the packet communication timing will not collide with the another station by detecting a signal from that station. Each of the communication stations in the network transmits a beacon describing information on the network and sets a state for performing reception operation at the time band before and after the transmission of the beacon signal. By performing this processing, when no transmission/reception data is present in each communication station in the network, the system can be configured with the minimum transmission/reception operation. Moreover, according to the fluctuating transmission/reception data amount, the transmission/reception operation is changed. Thus, it is possible to transmit data with the minimum latency by the least necessary transmission/reception operation.
(FR) La présente invention permet d'éviter les problèmes de retenue des données à l'émission et de retard à la réception dans un système de communication tel qu'un LAN radio. A cet effet, on réalise le contrôle d'accès à l'émission de façon que la synchronisation utilisée pour les paquets ne soit pas en concurrence avec les émissions d'autres stations, ce qui nécessite de détecter les signaux en provenance de cette station. Chacune des stations de communication du réseau émet donc une information de description de balise sur le réseau et définit un état permettant de mener les opérations de réception dans la bande de synchronisation avant et après émission du signal balise. Ce processus permet, en l'absence d'émission ou de réception de données dans chacune des stations de communication du réseau, de configurer le système avec un minimum d'opérations d'émission et de réception. De plus, le fonctionnement de l'émission et de la réception s'adapte aux fluctuations de la quantité de données à émettre ou à recevoir. Cela permet de réduire au minimum les temps d'attente pour l'émission des données, et ce, avec un minimum d'opérations d'émission et de réception.
(JA) 無線LANシステムなどの通信システムでの伝送時の、送信側での滞留や受信側での遅延などの問題を解決するために、他の局から送信される信号の検出により、他局とパケットの通信タイミングが衝突しないアクセス制御を行う場合に、ネットワーク内の各通信局は、ネットワークに関する情報を記述したビーコンを送信して、そのビーコン信号の送信に前後する時間帯に受信動作を行う状態を設定するようにした。かかる処理を行うことで、ネットワーク内の各通信局で送受信データが存在しない場合には、最小限の送受信動作にてシステムを構成可能であり、かつ、変動する送受信データ量に従って、送受信動作状態を変遷させることにより、必要最低限の送受信動作にて、極力小さなレイテンシでのデータ転送を可能とすることができる。
