Abstract

The invention discloses a communication method and communication device, which are used for reducing service interruption time and signaling overhead generated by the change of an access point for providing a communication service for a site due to the position movement or direction change of the site. In this regard, the scheme is provided, wherein the sending addresses contained in the first frame sent to the station by different access points in the access point set are the same; Thus, when the sending position of the station moves or the direction of the station changes, the access point providing the communication service for the station is changed from one access point in the access point set to another access point; Due to the fact that the sending addresses contained in the first frame sent by the access points in the access point set are the same, the station can consider the access point set as one access point, the station does not need to execute the access point switchingprocess, and station service interruption and signaling overhead caused by the access point switching process are avoided.

Description

technical field

[0001] The present application relates to the technical field of wireless communication, and in particular to a communication method and device. Background technique

[0002] The use of high frequency band communication requires the use of narrow radiation beams with high antenna gain to overcome the high path loss defects of millimeter wave transmission, which is the so-called beam forming (Beam Forming) technology. In the beamforming technology, the transmitting device needs to determine the transmitting antenna and beam parameters with the best quality when transmitting data to the receiving device according to the beam feedback information provided by the receiving device.

[0003] Take the wireless-fidelity (Wi-Fi) system that uses high-frequency band communication as an example. In the Wi-Fi system, the location movement or direction change of a station (station, STA) may cause the station to provide communication The service access point (Access Point...

Embodiment Construction

[0109] The embodiments of the present application provide a communication method and device, which are used to reduce the service interruption time and signaling overhead caused by the change of the access point providing communication services for the station due to the location movement or direction change of the station. Wherein, the method and the device are based on the same inventive concept. Since the principles of the method and the device solve problems are similar, the implementation of the method and the device can be referred to each other, and the repetitions will not be repeated.

[0110] In the embodiment of the present application, the access point set includes the control access point and the member access point; different access points in the access point set send the same sending address contained in the first frame sent to the station, where the sending The address may include the identifier of the control access point in the access point set or the identifi...
