| 摘要 |
The present invention provides a data transmission method, including: receiving, by a station, an indication frame sent by an access point, where the indication frame is used to allocate a specified random contention channel; and sending, by the station, data over the specified random contention channel according to the indication frame and a random probability. The present invention can reduce contention between stations, thereby reducing a time for accessing a random contention channel by the stations. |
