Title:
WIRELESS COMMUNICATION SYSTEM, BASE STATION DEVICE AND WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/250896
Kind Code:
A1
Abstract:
A wireless communication system having different propagation delay between a base station device and a plurality of terminal devices that use time division multiplexing for duplexing. At least either the base station device or a terminal device has a delay calculation unit that calculates the propagation delay for each terminal device. The base station device has a control unit that changes the frame configuration so as to shorten the wait time for switching between an uplink frame and a downlink frame, in accordance with the propagation delay for each terminal device. As a result, extra wait time can be reduced and transmission capacity can be increased.
