METHOD FOR TRANSMITTING AND RECEIVING DATA UNIT BASED ON UPLINK MULTIPLE USER MULTIPLE INPUT MULTIPLE OUTPUT TRANSMISSION AND APPARATUS FOR THE SAME |
摘要 |
In an aspect, a method of receiving a data unit, performed by an Access Point (AP), in a Wireless LAN (WLAN) system is provided. The method includes transmitting a signal protection frame, the signal protection frame comprising a group ID field indicating a Multiple Input Multiple Output (MIMO) transmission STA group including a first station (STA) and a second STA; and, a spatial stream field indicating a number of spatial streams allocated to each of member STAs included in the MIMO transmission STA group; receiving a first preamble for a first data unit from the first STA; receiving a second preamble for a second data unit from the second STA; and simultaneously receiving the first data unit from the first STA and the second data unit from the second STA. |
