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.
