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 5):
The method according to  claim 3 , wherein sending, on the reserved first channel, the data to the second device comprises: sending, by the first device, on the reserved first channel, the data to a plurality of second devices via downlink multi-user transmission;\n wherein the method further comprises: sending, by the first device, on the reserved second channel, response request frames corresponding to the data to the plurality of second devices; wherein: in case the plurality of second devices support uplink multi-user transmission, the plurality of second devices, in response to receiving the response request frames, send acknowledgements (ACKs) to the first device at a same time via uplink multi-user transmission before a minimum time for reaching maximum cache capacities of the first device; or in case the plurality of second devices do not all support the uplink multi-user transmission, the plurality of second devices, in response to receiving the response request frames, calculate the times for reaching the maximum cache capacities of the first device, based on rates carried by the preamble at which the first device sends respectively the data to the plurality of second devices, and the plurality of second devices send respectively the ACKs to the first device before the times for reaching the maximum cache capacities of the first device; or the plurality of second devices send on the second channel the ACKs to the first device in a limited contention-free manner; and wherein receiving, on the reserved second channel, the ACK corresponding to the data comprises: receiving, by the first device, on the second channel, the ACKs corresponding to the data from the plurality of second devices.
