Abstract: A device synchronization method in D2D communication implements synchronization between devices. One such method includes receiving first device-to-device (D2D) synchronization information sent by a first device in a D2D communication, including a secondary D2D synchronization signal (SD2DSS). The method further includes determining a synchronization source identifier and a forwarding hop count according to preset correspondences between the SD2DSS and the synchronization source identifier and between the SD2DSS and the forwarding hop count. A synchronization source which corresponds to the synchronization source identifier is synchronized with. The forwarding hop count in the first D2D synchronization information is updated in response to determining that the forwarding hop count in the first D2D synchronization information is less than a set threshold, to obtain second D2D synchronization information, and the second D2D synchronization information is sent.

Abstract: A communication control method and a related apparatus are disclosed. A communication control method includes transmitting, by a base station, a configuration message to N user terminals in a cell, where the configuration message carries a secondary configuration indication, and the secondary configuration indication is used to indicate a secondary transmission configuration configured by the base station for the N user terminals, where the secondary transmission configuration of the N user terminals is different from a primary transmission configuration of M user terminals in the cell. The method also includes obtaining, by the base station, interference parameters about interference that the N user terminals receive from neighboring user terminals in a full-duplex subframe, and activating the secondary transmission configuration for K user terminals in the N user terminals by using an activation message.
