Title:
WIRELESS QUALITY PREDICTION METHOD AND WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/112263
Kind Code:
A1
Abstract:
In order to provide a wireless quality prediction method which can easily adapt to a change in wireless quality even when the transmission environment has changed, this wireless communication system performs: an acquisition process for acquiring the current position of a user terminal, an estimated position of the user terminal after a prescribed time has elapsed, and an actual measurement value of received power of the user terminal at the current position; a first prediction process for using a received power predictor to predict a first predicted value, which is the predicted value of the received power at the current position, and a second predicted value, which is the predicted value of the received power at the estimated position; a correction process for finding, on the basis of the result of comparing the actual measurement value of the received power and the first predicted value, a third predicted value which is obtained by the correcting the second predicted value; and a second prediction process for using a wireless quality predictor and the third predicted value to predict the wireless quality of the user terminal at the estimated position.
