Title:
WIRELESS COMMUNICATION SYSTEM AND WIRELESS COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/059407
Kind Code:
A1
Abstract:
[Problem] To provide a technique which can avoid a deterioration in the quality of a received signal or a breakdown of signal synchronization in a TDD-type wireless communication system which enhances transmission efficiency by making correlation position protection and an adaptive frame length control compatible with each other.
[Solution] In a base station, a signal synchronization unit 114 detects a reception timing of a signal from a mobile station, a correlation position protection unit 115 corrects the detected reception timing on the basis of a time from a transmission timing at which a signal transmission operation to the mobile station has started to the detected reception timing, a transmission timing generation unit 118 generates, on the basis of a reception timing after the correction, a transmission timing at which a next signal transmission operation to the mobile station will start, an FB frame generation unit 119 generates frame cycle information that indicates a correction amount by the correlation position protection unit 115, and a transmission processing unit 120 transmits, to the mobile station, a signal including the frame cycle information in response to the generation of the transmission timing.
