Method for uplink multi-user transmission in wireless communication system and apparatus therefor
First Claim
1. A method for performing uplink (UL) multi-user (MU) transmission by a station (STA) in a wireless communication system, the method comprising:
- receiving a Medium Access Control (MAC) frame from an access point (AP), the MAC frame comprising a MAC header, a frame body and a Frame Check Sequence (FCS), the MAC header including a field indicating whether a type of the MAC frame is a trigger frame; and
transmitting a UL frame in response to the MAC frame to the AP, when the type of the MAC frame is the trigger frame,wherein the trigger frame includes information for the UL MU transmission and information indicating a type of the trigger frame,wherein the type of the trigger frame includes a type for triggering transmission of UL MU data frames or a type for triggering transmission of buffer status report frames, andwherein the UL frame is a UL MU data frame when the type of the trigger frame includes the type for triggering transmission of UL MU data frames.

Abstract
In the present invention, disclosed is a method for uplink multi-user transmission in a wireless communication system and an apparatus therefor. Specifically, a method for performing, by a station (STA), uplink (UL) multi-user (MU) transmission in a wireless communication system comprises the steps of: receiving, from an access point (AP), a trigger frame including information for UL MU transmission; and transmitting an UL MU PPDU on the basis of the information for UL MU transmission, wherein the trigger frame is a medium access control (MAC) frame, a MAC header of the trigger frame includes a type field and a subtype field, and the type of the trigger frame may be indicated by the type field and the subtype field.
