Method for reliable broadcasting in wireless local area network

The invention relates to a method for reliable broadcasting in a wireless local area network, and belongs to the technical field of digital communication. The method comprises the following steps that: a wireless access point packs original data to be broadcasted into an original data packet, selects a channel encoding mode, performs channel encoding on the original data packet and broadcasts theencoded data packet to a mobile station in the form of broadcast message; the mobile station receives the encoded data packet, performs channel decoding on the encoded data packet and feeds back channel decoding state information to the wireless access point; the wireless access point receives the information and adjusts the rate of the broadcast transmission link; and if all the mobile stations decode the original data packet, the broadcasting of the current original data packet is finished; otherwise, a supplementary encode data packet is generated and broadcasted to the mobile station; andthe mobile station receive
