Abstract: Embodiments relate to a resource scheduling method, a base station, a scheduler, a program source server, and a system. A method includes receiving, a session start request message comprising carries an SAI corresponding to a program source from a program source server; sending the session start request message to a base station corresponding to the SAI; receiving a session start response message from the base station; adding the base station to an IP multicast group; sending a resource scheduling message comprising information about a MA resource allocated to the program source to the base station; and receiving a resource scheduling response message from the base station.

Abstract: A synchronous communication method is provided. The method includes: obtaining, by a first terminal, first configuration information, where the first configuration information includes a first parameter; determining, by the first terminal according to a global navigation satellite system (GNSS) clock, a transmission timeslot corresponding to a current moment in a device-to-device (D2D) communications system; determining, by the first terminal according to the transmission timeslot and the first parameter, whether the current moment is a synchronization-information-sending moment; if the current moment is the synchronization-information-sending moment, sending, by the first terminal, sidelink synchronization information at the synchronization-information-sending moment, where the sidelink synchronization information carries indication information, the sidelink synchronization information is used to synchronize a second terminal with the first terminal, and the indication information is used to indicate, to the second terminal, that the first terminal is a synchronization source that uses the GNSS clock.

Abstract: This application provides example optical communications apparatuses. One example optical communications apparatus includes a control apparatus and an optical module matching apparatus. The control apparatus can output a first control signal to the control end. An input end of the optical module matching apparatus can connect to a first optical module and receive a first electrical signal output by the first optical module. An output end of the optical module matching apparatus can output a first serial signal. The control apparatus can output a second control signal to the control end. The input end of the optical module matching apparatus can receive a second electrical signal output by the second optical module. The output end of the optical module matching apparatus can output a second serial signal. The first electrical signal and the second electrical signal can have different level types.

Abstract: A synchronization information sending method, a synchronization information receiving method, a base station, and a communications node are provided. The sending method includes: obtaining, by a communications node, a pulse per second PPS; obtaining, by the communications node, a first time T1 based on the PPS; obtaining, by the communications node, a second time T2 based on the subframe; determining, by the communications node, a first time difference TD 1 based on the first time T1 and the second time T2; obtaining, by the communications node, a second time difference TD 2 based on the first time difference TD 1 and the TA. Different base stations use a same pulse per second PPS as a reference to adjust a sending time, a radio frame number, and a subframe number of a subframe, so that the different base stations are synchronized with each other.
