Title (EN) COMMUNICATIONS SYSTEM
(FR) SYSTÈME DE COMMUNICATION
(JA) 通信システム
Abstract:
(EN) A communication device (100) generates, for each of a plurality of frequencies, a measurement frame including transmission timing information therein that indicates timing with which a prescribed measurement frame is transmitted, and transmits the generated measurement frame with the timing indicated by the transmission timing information included in the measurement frame, and a communication device (200) measures, for each of the plurality of frequencies, the reception timing with which the transmitted measurement frame is received, calculates for each of the plurality of frequencies a delay time of the measurement frame on the basis of the transmission timing indicated by the transmission timing information included in the received measurement frame and the measured reception timing, and equilibrates the calculated delay time over a span of the plurality of frequencies.
(FR) Selon l’invention, un dispositif de communication (100) génère, pour chacune d'une pluralité de fréquences, une trame de mesure contenant des informations d’instant de transmission qui indiquent un instant auquel une trame de mesure prescrite est transmise, et transmet la trame de mesure générée à l’instant indiqué par les informations d’instant de transmission contenues dans la trame de mesure ; et un dispositif de communication (200) mesure, pour chacune de la pluralité de fréquences, l’instant de réception auquel la trame de mesure transmise est reçue, calcule pour chacune de la pluralité de fréquences un temps de retard de la trame de mesure sur la base de l’instant de transmission indiqué par les informations d’instant de transmission contenues dans la trame de mesure reçue et l’instant de réception mesuré, et équilibre le temps de retard calculé sur une étendue de la pluralité de fréquences.
(JA) 通信装置(100)が、複数の周波数それぞれについて、所定の測定フレーム送信するタイミングを示す送信タイミング情報を測定フレームに含めて測定フレームを生成し、生成した測定フレームを、測定フレームに含まれた送信タイミング情報が示すタイミングで送信し、通信装置(200)が、送信されてきた測定フレームを受信した受信タイミングを、複数の周波数ごとに測定し、受信した測定フレームに含まれる送信タイミング情報が示す送信タイミングと、測定した受信タイミングとに基づいて、測定フレームの遅延時間を、複数の周波数ごとに算出し、算出した遅延時間を複数の周波数にわたって平衡化する。
