UPLINK MULTI-USER TRANSMISSION RESPONSE METHOD, APPARATUS AND DEVICE

WIPO Patent Application WO/2017/101017

A1

Provided are an uplink multi-user transmission response method, apparatus and device. The method comprises: sending a trigger message, wherein the trigger message is used to trigger at least two stations to send an uplink message; receiving the uplink message; and sending an acknowledgement message, wherein the acknowledgement message comprises acknowledgement information about the uplink message and a multicast address, and the multicast address is an address corresponding to a station group constituted by the at least two stations or a specific address allocated to a station group receiving the acknowledgement message. By means of the uplink multi-user transmission response method in the embodiments of the present invention, an access point can acknowledge, by only sending one acknowledgement message, a plurality of stations that the sent data is received successfully, so that the sending efficiency of the acknowledgement message is improved; and at the same time, the acknowledgement message carries a multicast address, so that the station can recognize whether the acknowledgement message contains acknowledgement information about the station more quickly, and thus the station unrelated to the acknowledgement message can discard the acknowledgement message quickly, which reduces the power consumption of the station.
