Title:
BEAM TRAINING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/093940
Kind Code:
A1
Abstract:
Provided by the present application are a beam training method and device, the method comprising: a first receiving device among M receiving devices generates and transmits a configuration frame, the configuration frame comprising M pieces of time information, wherein each piece of time information corresponds to a receiving device among the M receiving devices respectively, is used to indicate a feedback information transmission time of the corresponding receiving device, and is also used to indicate a confirmation information receiving time of the corresponding receiving device, M being an integer greater than or equal to 1; the first receiving device receives a sector scanning SSW frame sent by a transmitting device; the first receiving device generates feedback information according to the SSW frame; the first receiving device transmits the feedback information at the feedback information transmitting time indicated by the corresponding time information; and the first receiving device receives confirmation information for the feedback information which is transmitted by the transmitting device at the confirmation information receiving time indicated by the corresponding time information, thereby shortening the training time and reducing the signaling overhead.
