Abstract: The present disclosure discloses a signal sending method and device. The method includes: receiving, by a base station, an uplink pilot signal sent by authorized user equipment, and determining a direction vector parameter and a first channel fading parameter of a channel calculating, according to the direction vector parameter and the first channel fading parameter, a first signal beamformer parameter, determining a transmission area of an artificial noise signal according to the direction vector parameter, and calculating a second signal beamformer parameter; and processing a to-be-transmitted signal by using the first signal beamformer parameter and the second signal beamformer parameter, and transmitting the processed signal. In this way, in a non-target direction, energy leakage of the secrecy signal to the authorized user equipment is relatively small, and transmitted artificial noise signals are concentrated in an area with a relatively high secrecy signal leakage risk.

Abstract: Backup management methods, systems, devices, and media are disclosed. A network device is connected to a terminal device. The network device determines whether a backup task associated with the terminal device exists, where the backup task is used to store to-be-backed-up target data in the terminal device in a destination storage device, and the destination storage device is connected to the network device. If the network device determines that the backup task exists, the network device indicates the terminal device to start the backup task, to store the target data in the destination storage device.

Abstract: Example adaption apparatus are described. An example adaption apparatus includes a first USB interface and a second USB interface. A power signal of the first USB interface is electrically connected to a power signal of the second USB interface. A first channel configuration signal of the first USB interface is electrically connected to an ID signal of the second USB interface using a first resistor. The ID signal of the second USB interface is electrically connected to the power signal of the second USB interface using a second resistor. A resistance value of the first resistor meets a criterion followed by a first device to identify a UFP device according to the USB Type-C protocol. A sum of the resistance value of the first resistor and a resistance value of the second resistor meets a criterion followed by the first device to identify a DFP device according to the USB Type-C protocol.

Abstract: A data transmission method and a device are provided. When determining that the first network element and the second network element is disconnected, the first network element stores identification information of the last frame of data and connection status information that are transmitted before the connection is disconnected. When determining a condition for re-communication is meet, the first network element generates a third key based on a first key and a second key, where the first key is a key used to transmit the last frame of data, and the second key includes a key used by the first network element and the second network element to transmit each of j frames of data before the last frame of data. The first network element communicates with the second network element based on the third key, identification information of an ith frame of data, and the connection status information.
