Title:
NODE DEVICE, COMMUNICATION SYSTEM, CONTROL CIRCUIT, STORAGE MEDIUM, AND SYNCHRONIZATION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/106206
Kind Code:
A1
Abstract:
A base station (1A), which is a node device, having a function for synchronizing with a node device of a communication counterpart is characterized by including: a signal transmission unit (10) for transmitting a signal to the node device of the communication counterpart; a signal reception unit (11) for receiving a signal from the node device of the communication counterpart; a timing-difference detection unit (12) for detecting a timing difference between the base station and the node device of the communication counterpart by using the transmission timing at which the signal transmission unit transmits a signal and the reception timing at which the signal reception unit receives a signal from the node device of the communication counterpart; a weighting holding unit (13) for holding weighting information of each of a plurality of node devices; a timing-correction-level calculation unit (14) for calculating a timing correction level by weighted-averaging the timing difference on the basis of the weighting information of the node device of the communication counterpart; and a transmission-signal generation unit (16) serving as a transmission-timing adjusting unit for adjusting the transmission timing by using the timing correction level.
