Title:
METHOD FOR TRANSMITTING AND RECEIVING SIGNAL IN OPTICAL WIRELESS COMMUNICATION SYSTEM, AND TRANSMITTING TERMINAL AND RECEIVING TERMINAL THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/262744
Kind Code:
A1
Abstract:
A method of receiving, by a receiving terminal, a signal in optical wireless communication is proposed. The method may comprise: establishing a communication link for performing the optical wireless communication with a transmitting terminal; receiving an optical signal from the transmitting terminal through the communication link; and performing interference cancelation on the optical signal. Here, establishing the communication link comprises transmitting and receiving initial information with the transmitting terminal, wherein the initial information may include an orbital angular momentum (OAM) mode applied to the optical signal. In addition, the interference cancelation may be performed on the basis of the OAM mode.
