Abstract: Disclosed are a method for determining a weighting parameter of beamforming, and a computer storage medium, belonging to the technical field of WLANs. The method comprises: an AP in a WLAN sending a scheduling frame, with the scheduling frame being used for instructing each STA that receives the scheduling frame to use a corresponding reference space-time stream quantity to send an uplink data frame. Therefore, an AP can set a reference space-time stream quantity of each STA according to requirements. For example, the reference space-time stream quantity can be set as the maximum space-time stream quantity that can be used by the corresponding STA, such that when a downlink weighting parameter is determined for the STA, as many beamforming directions as possible can be considered, reducing the probability of omission of a downlink maximum weighting direction, and thus improving the multiplexing gain of a WLAN system while improving the reception signal-to-noise ratio of the STA.
