Title:
BEAM TRAINING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/057390
Kind Code:
A1
Abstract:
The present application provides a beam training method and device. The method comprises: an access point (AP) sending training configuration information to a plurality of stations (STA); the STAs each determining, according to the training configuration information, a second uplink beam for sending a training frame, and sending the training frame to the AP on the basis of the corresponding second uplink beam; and the AP determining, on the basis of the training frames sent by the STAs, third uplink beams to be used by the STAs when sending uplink data. In contrast to the prior art in which the STA sends training frames on all of the uplink beams, the method and device of the present application can be used to improve the efficiency of beam training.
