Disclosed are a wireless signal transmission method and system, the method comprising: a sending station sends a wireless signal to a plurality of receiving stations, the wireless signal comprising a first portion and a second portion, the first portion being divided into a trigger frame which has a first frame format type and can be independently decoded, the second portion being divided into a specific signal which has a second frame format type; the sending station receives a wireless frame sent by at least one receiving station within the plurality of receiving stations. The wireless signal transmission method and system are used to solve the problems in the prior art that a trigger frame is not able to complete transmission resources reservation and trigger multi-user transmission at the same time as satisfying the training accuracy required for uplink multi-user transmission, and that it is not possible to ensure that a station will have enough time to prepare uplink data after receiving a trigger frame. |
