Title:
MULTI-STATION COOPERATION-BASED DATA TRANSMISSION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/218989
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are a multi-station cooperation-based data transmission method and device, the method comprising: a station receiving second data from other stations besides the station in a cooperation group to which the station belongs; the station sending first data to the other stations, and the other stations generating a second aggregation frame comprising the first data and the second data; the station sending a first aggregation frame to an access point, the first aggregation frame comprising the first data and the second data; the time at which the first aggregation frame is sent by the station is the same as the time at which the other stations send the second aggregation frame to the access point, and the order of aggregation of the data in the first aggregation frame is the same as that of the data in the second aggregation frame; the transmission power of the station sending the first aggregation frame is less than the power when the station individually sends the first data to the access point; the transmission power of the other stations sending the second aggregation frame is less than the power when the other stations individually send the second data to the access point. Thus, the transmission power of a single station is reduced, and the service life of the station is prolonged.
