Title:
METHOD FOR TRANSMITTING AND RECEIVING SIGNAL IN OPTICAL WIRELESS COMMUNICATION SYSTEM, AND TRANSMISSION TERMINAL AND RECEPTION TERMINAL THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/262743
Kind Code:
A1
Abstract:
A method by which a transmission terminal transmits a signal in an optical wireless communication system can comprise: transmitting a first optical signal including a reference signal to a reception terminal having established a communication link with the transmission terminal; receiving feedback information about the first optical signal from the reception terminal; and transmitting a second optical signal to the reception terminal on the basis of the feedback information, wherein an orbital angular momentum (OAM) mode of the second optical signal can be selected on the basis of the feedback information.
