Abstract: A communication link initialization method includes that a master node sends a first information frame to a slave node. The first information frame includes first synchronization information. The slave node implements synchronization with the master node based on the first synchronization information. The slave node sends a second information frame to the master node. The second information frame includes second synchronization information. The master node implements synchronization with the slave node based on the second synchronization information. The master node sends a third information frame to the slave node. The third information frame is used to indicate a first training information frame. The slave node trains a link between the master node and the slave node based on the third information frame. The slave node sends a fourth information frame to the master node.

Abstract: The present disclosure discloses a method, a device and a system for performing NAV control on a node and a node. The method includes: updating a local NAV value to a preset first value when it is determined that a preset first field of a monitored MAC frame carries a first identity, wherein the first value is less than a current local NAV value and the MAC frame of which the preset first field carriers the first identity is transmitted by a TXOP responder after receiving a last MAC frame transmitted by a TXOP holder. The method, device, system and node may enable a hidden station to enter a channel access competition state timely, thereby solving a problem of regional discrimination of a station.

Abstract: Embodiments of this application disclose a data processing method, which can be applied to a clock synchronization network system. The system can correct, based on a clock frequency error or a time error, a data timestamp of a data packet collected by the system in a time period in which there is no reference clock, so that a corrected system time of the data packet is consistent with a reference time. This improves accuracy of data record.
