Abstract: The present invention provides a method and an apparatus for handling full-duplex interference. One method includes: obtaining an interference degree that is caused when a site device performs full-duplex transmission with at least two UEs; and determining, according to the interference degree, a UE allowed to transmit uplink and downlink signals on the same time and frequency resource among the at least two UEs. In embodiments of the present invention, a UE allowed to transmit uplink and downlink signals on the same time and frequency resource may be classified according to an interference degree that is caused when a site device performs full-duplex transmission with at least two UEs, thereby preventing the interference problem in the scenario of point-to-multipoint full-duplex communication as much as possible.

Abstract: This application discloses a clock synchronization method and a related apparatus in a distributed system. The distributed system includes a plurality of nodes, and the plurality of nodes include a master node and a plurality of slave nodes. The master node obtains a plurality of local clock offsets, where each of the plurality of local clock offsets indicates a clock offset between two nodes in the distributed system. The master node determines a global clock offset of a target slave node relative to the master node based on the plurality of local clock offsets, and sends the global clock offset to the target slave node. The target slave node obtains a clock reference value of a local clock, and then performs clock synchronization based on the clock reference value and the global clock offset.
