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: The present disclosure relates to signal transmission methods, apparatuses, and systems. One example method includes sending a narrow band signal to a receive end, where the narrow band signal is used by the receive end to determine initial time-frequency synchronization information, and sending an ultra-wideband signal to the receive end, where the ultra-wideband signal includes a channel impulse response training sequence (CTS) field, the CTS field is used by the receive end to determine a channel impulse response, the CTS field includes at least one CTS symbol, and the CTS symbol includes at least one first preamble symbol or is generated by spreading at least one first preamble symbol.

Abstract: The technology of this disclosure relates to a chip packaging apparatus. The chip packaging apparatus includes a first differential pin pair, a first pin, and a second pin. The first differential pin pair includes a first differential signal pin and a second differential signal pin. In addition, the first pin and the second pin are both located between the first differential signal pin and the second differential signal pin, and the first pin and the second pin are differential signal pins (or both are power pins). The first pin is adjacent to the first differential signal pin and the second differential signal pin. The second pin is adjacent to the first differential signal pin and the second differential signal pin. The first pin and the second pin are respectively located on two sides of a first imaginary straight line connecting the first differential signal pin to the second differential signal pin.
