In implementations of the present disclosure, there is provided an approach for scheduling uplink traffic of a station. A method comprises determining a type of uplink traffic from a station (STA), wherein the type of uplink traffic is associated with a traffic size and an urgency. The method further comprises determining uplink scheduling information for the STA based on the traffic size and the urgency, wherein the uplink scheduling information indicates at least one of: a UL-OFDMA scheduling manner or a UL-MU-MIMO scheduling manner. The method further comprises sending the uplink scheduling information to the STA, and receiving uplink traffic from the STA using the uplink scheduling information. Implementations of the present disclosure can help AP to schedule the STA(s) more intelligent, effective and accurate, and thus the user experience can be enhanced and the transmission performance can be improved.
