Abstract: The invention provides a method, an apparatus and a system for controlling network congestion. The method includes: sending a control frame or a beacon frame to a station in a network when network congestion occurs, so as to instruct the station to enlarge a contention window when the station needs to send data. The method can achieve the congestion control for a network before collision occurs to a station, avoiding more serious network congestion caused by each station still contending for a channel after the network congestion occurs; since an access point can send a control frame or a beacon frame to the station when determining that congestion occurs to the current network, to instruct the station which needs to send data to re-determine a backoff time, a rapidly congestion relief of the whole network is achieved, and also a fair channel contention of each station is guaranteed.

Abstract: Disclosed is a data transmission method. The method comprises: reserving a first channel and a second channel, where the first channel is used for transmitting data and the second channel is used for transmitting ACKs; sending data to a receiving end on the first channel that is reserved; receiving an ACK that is sent by the receiving end and corresponds to the data on the second channel that is reserved and determining whether the data needs to be cached based on information carried in the ACK; and if the information carried in the ACK indicates that the receiving end has correctly received the data, clearing the data that is cached by a sending end. Through separate transmission of the data and the ACK, an efficiency problem of the sending end in providing MAC in a wireless system in a condition of a limited cache capacity is resolved.
