Abstract: This application discloses a database system update method, applied to a database including a first node, a second node, and a shared storage device. The method includes: The first node sends a first instruction to the second node, where the first instruction is used to request storage location information of first data in the shared storage device, and the first data is data transferred by the second node to the first node for processing; and the first node obtains first information sent by the second node, and obtains mapping information from the shared storage device based on the first information, where the mapping information indicates a storage location of the first data in the shared storage device. The method is used to improve update efficiency of the database system, and ensure that different nodes can simultaneously process different data in a shared storage device.

Abstract: A transceiver with a spectrum sensing unit configured to detect, within a plurality of millimeter wave bands, one or more channels with tolerably low interference for selection. The transceiver has a transmitter configured to modulate a transmit signal to an output transmit signal using a transmit carrier frequency compatible with a transmit channel selected from the one or more channels, and using a transmit duplexing operating mode compatible with a transmit millimeter wave of the plurality of millimeter wave bands that correspond to the transmit channel. The transceiver has a receiver configured to demodulate a receive signal from an input receive signal using a receive carrier frequency compatible with a receive channel selected from the one or more channels, and using a receive duplexing operating mode compatible with a receive millimeter wave of the plurality of millimeter wave bands that correspond to the receive channel. The transceiver has a duplexer configured to route the output transmit signal from the transmitter based on the transmit duplexing operating mode and the transmit millimeter wave band, and the input receive signal to the receiver based on the receive duplexing operating mode and the receive millimeter wave band.
