Abstract: The present disclosure relates to optical wireless communication methods and devices. In one example method, a first communication device receives optical signals separately transmitted by N nodes, and obtains, based on the received optical signals of the N nodes, first parameters that are of the N nodes and that are used to locate the first communication device and an information bit stream corresponding to each node. The optical signals are obtained by the nodes by performing electrical-to-optical conversion on a first signal, the first signal is a signal obtained by adding a direct current bias signal to a second signal, and the second signal is a signal obtained after constant envelope modulation is performed on an information bit stream to be sent by a light source node to the first communication device.

Abstract: The fluorescent antenna includes at least one layer of fluorescent array, the fluorescent array includes a plurality of fluorescent units, and an isolation layer used to isolate emergent optical signals converted by adjacent fluorescent units is included between adjacent fluorescent units. The fluorescent units include at least one fluorescent region; and when the fluorescent antenna includes one layer of fluorescent array, the fluorescent units are all fluorescent regions; or when the fluorescent antenna includes at least two layers of fluorescent arrays, the fluorescent unit further includes at least one transparent region. In two adjacent layers of fluorescent arrays, a transparent region of the first layer overlaps a fluorescent region of the second layer, and an incident optical signal arrives at the fluorescent region of the second layer through the transparent region of the first layer.

Abstract: This application provides a full-duplex self-interference weakening method and a full-duplex self-interference weakening system. The full-duplex self-interference weakening method includes: separately receiving, by a first port of a dual-polarized receive antenna and a second port of the dual-polarized receive antenna, a signal sent by a transmit antenna; and adjusting and combining the signal received by the first port of the dual-polarized receive antenna and/or the signal received by the second port of the dual-polarized receive antenna, to weaken interference caused by the transmit antenna to the dual-polarized receive antenna. The full-duplex self-interference weakening method and the full-duplex self-interference weakening system provided in this application resolve a problem that a quantity of antennas and an antenna location are limited in an existing antenna interference cancelation method.

Abstract: This application provides a random access method and apparatus applicable to satellite communication. The method includes: obtaining a round-trip transmission latency tRTD of a signal between a terminal device and a satellite; obtaining a random access parameter based on the tRTD, where the random access parameter includes one or more of: a duration between a moment at which the terminal device sends a random access preamble and a moment at which the terminal device starts to receive a random access response RAR, a duration of a window in which the terminal device receives the RAR, a duration between a moment at which the terminal device stops receiving the RAR and a moment at which the terminal device sends the random access preamble again, and a subframe duration; and receiving, by the terminal device the RAR based on the random access parameter.

Abstract: This application provides an example data transmission method, a related example device, and an example system. One example method may include receiving, by a terminal device, indication information sent by a network-side device, where the indication information is used to indicate a receiving time period, and the receiving time period is after a power saving mode (PSM) period. The method also includes obtaining, by the terminal device, a timing advance (TA) value in the receiving time period. The method also includes sending, by the terminal device, data to the network-side device based on the TA value.
