Abstract: A beamforming-based communication method includes: obtaining cell information; when the cell information meets a preset low-load condition, dividing to-be-processed broadcast messages into a plurality of broadcast message groups; determining, based on a preset correspondence between a broadcast message and a broadcast beam, a broadcast beam group corresponding to each broadcast message group and a broadcast beam for sending no broadcast message in each time window; sending the broadcast message group in each time window by using the broadcast beam group; and shutting down, in each time window, the broadcast beam for sending no broadcast message. Some broadcast beams are used in each time window to send the broadcast message, and the broadcast beam for sending no broadcast message is shut down.

Abstract: Embodiments provide a packet processing method. In accordance with this method, a first LSP packet can be received by a network device. The following determinations can be made: that the network device stores no LSP packet whose LSP ID and PDU type are the same as an LSP ID and PDU type of the first LSP packet; that the network device has stored a second LSP packet whose LSP ID is the same as an LSP ID of the first LSP packet and PDU type is the same as a PDU type of the first LSP packet, and that a sequence number of the second LSP packet is less than a sequence number of the first LSP packet. When one or more of these determination are made, a determination whether LSP packet digest information matching the first LSP packet exists can be made. When the LSP packet digest information matching the first LSP packet is determined to exist, the first LSP packet can be stored.

Abstract: Embodiments of this application disclose an interference coordination method and an apparatus. The method includes: A first TDD system and a second TDD system are adjacent asynchronous TDD systems of each other, the first TDD system communicates with UE in a first slot by using a first specified frequency domain resource, and the second TDD system communicates with the UE in a second slot by using a second specified frequency domain resource, where the first specified frequency domain resource is different from the second specified frequency domain resource. Alternatively, the first TDD system modifies a slot configuration of a third slot corresponding to the first slot when communicating with the UE in the first slot, and the second TDD system modifies a slot configuration of a fourth slot corresponding to the second slot when communicating with the UE in the second slot. The first slot and the second slot have same time domain positions and different functions.
