Title:
CONTROL DEVICE AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2020/039673
Kind Code:
A1
Abstract:
A suppression processing unit 52 controls communication by a first wireless communication terminal when a propagation delay greater than or equal to a threshold is detected in a time-division-duplexing uplink between the first wireless communication terminal and a first wireless base station. In accordance with a propagation delay between a wireless communication terminal DR1 and a wireless base station BS1, the wireless communication terminal DR1 transmits UL data earlier by an amount of time equal to the propagation delay. Consequently, it is possible that a communication trouble occurs in a wireless communication terminal DR2 and an MT1 connected to a wireless base station BS2 different from the wireless base station BS1 to which the wireless communication terminal DR1 is connected by wireless. Accordingly, the suppression processing unit 52 controls communication by the wireless communication terminal DR1 and thereby suppresses this communication trouble.
