Abstract: Embodiments of this application disclose a radio frequency resource allocation method, apparatus, device, system, and a storage medium. The method includes: obtaining radio frequency information of an access point AP (for example, RSSI signal strength between the AP and each neighboring AP, and data traffic of the AP in a data collection period), predicting, based on the radio frequency information of the AP, load of the AP that is in target duration after a current moment, and allocating a radio frequency resource to the AP based on the load of the AP. This implementation can reduce actual interference on an entire network and improve user experience.

Abstract: Embodiments of this application disclose a group-based calibration method and device. The method includes: A control device that obtains path loss data of a wireless access point AP set, where the AP set includes a plurality of APs, and the path loss data includes a path loss between any two of the plurality of APs. The control device obtains a first calibration group based on the path loss data, and sends first calibration information to a management AP of the first calibration group, where the management AP of the first calibration group is an AP that performs calibration management in the first calibration group. By implementing the foregoing method, the control device may divide a plurality of APs into a plurality of calibration groups based on path loss data between the APs, to decrease a coupling degree between the calibration groups.

Abstract: An antenna pattern selection method includes a first communication device sending a plurality of packets to a second communication device. Then, the first communication device measures, in each of a plurality of antenna patterns, signal quality of a plurality of acknowledgment frames with which the second communication device separately responds to the plurality of packets, and finally selects a dominant antenna pattern from the plurality of antenna patterns based on signal quality corresponding to each of the plurality of antenna patterns. According to the antenna pattern selection method, when normal communication is not affected, the first communication device may determine, based on signal quality of an acknowledgment frame, whether an antenna pattern used by the first communication device is proper.

Abstract: This application discloses a terminal roaming method and apparatus. A terminal sends, to a first AP associated with the terminal, an action frame that is used to request to associate with a second AP. A receiver address of the action frame is an address of the first AP, and the action frame further includes an identifier of the second AP. When the terminal receives a response frame sent by the first AP for the action frame, and the response frame indicates that association succeeds, the terminal establishes association with the second AP. The terminal first establishes the association with the second AP by using the first AP, and then changes an operating channel to an operating channel of the second AP. Now the terminal can receive and send data on the operating channel of the second AP.

Abstract: A channel indication sending method, a channel scanning method, and an apparatus are disclosed. The sending method includes: A first access point receives channel information from a second access point, where the channel information indicates that an operating channel of the second access point is a first channel, and whether the second access point successfully performs channel availability check (CAC) on the first channel, and the first channel is a dynamic frequency selection (DFS) channel. The first access point sends, on a second channel, a WLAN frame to a station associated with the first access point, where the WLAN frame includes an indication about the first channel and an indication of whether the second access point successfully performs the CAC on the first channel.
