Provided are a data transmission method and communication device, the communication device comprising: a transceiver used for sending a transmission frame to a second communication device, so that the second communication device obtains data information in the transmission frame; the transmission frame comprises a first part and a second part; the transceiver sends the first part of the transmission frame through a first number of subcarriers, and the transceiver sends the second part of the transmission frame through a second number of subcarriers, the first number being not equal to the second number; the transceiver is also used for performing the next information transmission with the second communication device. By dividing a transmission frame into two parts, each part being transmitted by different numbers of subcarriers, the communication device provided in an embodiment of the present invention can effectively increase throughput as required, and appropriately decrease throughput as required, thus enabling unlimited change in the throughput of the communication system. |
