Document Type and Number:
WIPO Patent Application WO/2021/250897
Kind Code:
A1
Abstract:
Provided is a wireless communication system having a propagation delay between a base station device and a terminal station device using time division multiplexing in a duplex operation, wherein the base station device and/or the terminal station device includes a delay calculation unit that calculates the propagation delay, and the base station device or the terminal station device includes a control unit that, in response to the propagation delay, changes the frame structure so as to shorten the wait time required to switch between an uplink frame and a downlink frame. Due to the foregoing, this invention can shorten excess wait time and improve transmission capacity.
