摘要： The present invention relates to the field of wireless communications, and in particular, to a multiuser access method and apparatus. The method is: broadcasting, by an AP, a first trigger frame to a STA within coverage of the AP, where the first trigger frame carries a preset condition, to request a STA that meets the preset condition to send an uplink access signal in a specified time after receiving the first trigger frame; receiving, by the AP, an uplink access signal sent by at least one STA, where the uplink access signal includes an identifier sequence; and when determining that an identifier sequence included in a received uplink access signal is the same as an identifier sequence included in a resource group allocated by the AP to a STA that sends the uplink access signal, determining, by the AP, that the STA that sends the uplink access signal meets the preset condition. Therefore, uplink resource use efficiency is effectively improved.

摘要： Embodiments of the present invention provide a data transmission method and a station. The method includes: transmitting, by a station, data of a primary AC of the station within a current TXOP, where to-be-transmitted data of the station includes the data of the primary AC and data of at least one secondary AC; after transmission of the data of the primary AC is completed, determining, by the station, whether there is remaining time in the TXOP; and if there is remaining time in the TXOP, transmitting, by the station, the data of the at least one secondary AC within the remaining time. According to the method provided in the embodiments of the present invention, the current TXOP is fully utilized without a channel resource wasted, thereby improving data transmission efficiency of the station.
