Title:
COMMUNICATIONS SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/163678
Kind Code:
A1
Abstract:
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.
