Abstract
An embodiment of the present invention provides an uplink access method based on an orthogonal frequency-division multiple access mechanism, comprising: determining the number of subchannels available for a current transmission and the number of time slot blocks required for the current access; transmitting uplink access trigger frames on the available subchannels; randomly selecting among the available subchannels and the time slot blocks; and transmitting an uplink access response frame to an access point by the randomly selected available subchannel and time slot block, to perform random access. The embodiment of the present invention can reduce an average time taken by users to access channels, thereby reducing transmission delay of data packet, reducing waste of time and subchannel resources, and improving the throughput of the entire network.
