Abstract: The present invention provides a vehicle to vehicle (V2V) communication method, a device, and a system, and relates to the field of communications technologies, to resolve a problem that scheduling overheads of physical downlink control channel (PDCCH) information are relatively large in existing V2V communication. The method may include receiving, by a first vehicle terminal, a first SPS configuration parameter that includes a first semi-persistent scheduling (SPS) period and that is sent by the base station. The method may also include receiving first scheduling control information that is used to instruct the first vehicle terminal to perform SPS activation and that is sent by the base station, and sending a V2V data packet to a second vehicle terminal.

Abstract: This application provides a sending device, a receiving device, an optical transmission system, and an optical power control method. The sending device includes a multiplexing unit and an optical power adjustment unit. The multiplexing unit is configured to send at least two communication optical waves to a fiber channel, and is further configured to send or receive at least two detection optical waves through the fiber channel. The optical power adjustment unit is configured to: obtain a power control instruction, where the power control instruction is generated according to power change information between the at least two detection optical waves. The optical power adjustment unit is further configured to perform optical power amplification and/or attenuation on at least one communication optical wave in the at least two communication optical waves according to the power control instruction.
