Communication method and device

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...

AI Technical Summary

Problems solved by technology

During this process, when a station performs access point search and access point switching, the service of the station will be interrupted for a period of time, and the station needs to perform interactive signaling when performing access point switching, so there is a certain amount of signaling overhead

[0004] To sum up, in the existing systems that use high frequency band communication, the location movement or direction change of the station will lead to the change of the access point that provides communication services for the station. There is a certain service interruption time and signaling overhead in this process.
