Abstract:
A multi-beam polling based transmission method and apparatus, and a communications device and an electronic device readable storage medium based on the method are disclosed. An access point AP broadcasts a beacon message, where the beacon message is used to indicate duration of a beacon period; and sends a data packet that includes channel use duration to a station STA, where the channel use duration is used to indicate a target slot at which the AP communicates with the STA within a duration range of the beacon period, so that the AP can communicate with the STA at the target slot.
Abstract:
Embodiments of the present disclosure provide a distributed storage method and a distributed storage device. The method includes offline merging, by a first thread service of a distributed storage system, M small files in a file system, generating, by the first thread service, M pieces of metadata in the offline merging process, loading, by a second thread service of the distributed storage system, the M pieces of metadata into a metadata set, searching, by the second thread service, the metadata set for metadata of a first small file when the second thread service receives a first instruction, and performing, by the second thread service, the operation corresponding to the first instruction when the second thread service finds the metadata of the first small file in the metadata set.
Abstract:
The present application provides a remote electrical tilt antenna management apparatus, system, and method, a remote controller, and a base station. The method includes: obtaining, by a remote control unit RCU, a first permission configuration file, where the first permission configuration file includes information about a first permission of a first base station to perform an operation on a first remote electrical tilt RET unit, and the first permission includes at least query or control; and configuring, by the RCU according to the first permission configuration file, the first permission of the first base station to perform an operation on the first RET. In this way, the first base station implements configuration of a management operation on the first RET, thereby implementing, by configuring different permission configuration files on the RCU, that a same base station manages different RETs, and further improving operability of managing a RET.
Abstract:
Embodiments of the present invention disclose a frequency mixing circuit and a method for suppressing local oscillation leakage in the frequency mixing circuit, where a mixed input signal and a local oscillation signal are involved, and local oscillation leakage can be effectively reduced by using a frequency mixing circuit whose structure is simpler and is easier to be implemented. The frequency mixing circuit includes a direct current bias circuit, where the direct current bias circuit includes a direct current bias voltage source used for reducing a local oscillation current. The frequency mixing circuit is mainly applied to frequency mixing, and especially to a case where an intermediate frequency signal is mixed with a local oscillation signal to output a radio frequency signal.
