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.

Claim (Index 15):
The method according to  claim 12 , wherein receiving the data from the first device on the first channel comprises: sending, by a plurality of first devices, on the first channel, the data to the second device via uplink multi-user transmission; and\n wherein the method further comprises: calculating, by the second device, latest times for reaching maximum cache capacities of the plurality of first devices based on rates carried by preambles at which the plurality of first devices send the data to the second device, so that before a minimum time for reaching the maximum cache capacities of the plurality of first devices, the second device sends acknowledgements (ACKs) to the plurality of first devices at a same time via downlink multi-user transmission; or sending, by the plurality of first devices, information regarding latest times to the second device, so that before the minimum time for reaching the maximum cache capacities of the plurality of first devices, the second device sends the ACKs to the plurality of first devices at a same time via downlink multi-user transmission; or calculating, by the second device, the times for reaching the maximum cache capacities of the plurality of first devices based on the rates at which the plurality of first devices send the data to the second device carried by the preambles, so that before the times for reaching the maximum cache capacities of the plurality of first devices, the second device sends the ACKs to the plurality of first devices; wherein sending, on the reserved second channel, the ACK corresponding to the data to the first device comprises: sending, by the second device, on the second channel, the ACKs to the plurality of first devices in a limited contention-free manner or via carrier sense multiple access (CSMA); and receiving, by the plurality of first devices, on the second channel, the ACKs corresponding to the data sent by the second device.
