Abstract
The invention discloses a beam domain optical wireless communication method and system. A base station is equipped with an array of optical transceiver ports or transmitter/receiver ports and a lens, each optical transceiver port forms a beam with centralized energy through the lens, and the base station generates beams in different directions by using the optical transceiver port array and the lens, thereby realizing multi-beam coverage or large-scale beam coverage in a communication region. The base station transmits/receives signals of multiple or a large number of user terminals by using channel state information of each user terminal, and different optical transceiver ports transmit/receive signals in different directions, thereby realizing simultaneous communication and bidirectional communication between the base station and different user terminals.
