Abstract:
Methods and apparatuses for multiple input-multiple output (MIMO) channel access are provided herein. A method performed by a station may include receiving, from an access point (AP), a frame including information indicating a broadcast address. The frame may further include a control trailer including information indicating that a multi-user multiple input-multiple output (MU-MIMO) frame is to be transmitted by the AP and information indicative of a designation of a plurality of STAs, the plurality of STAs including the STA. The frame may solicit response frames from at least the designated plurality of STAs. The method may further include transmitting a response frame to the indicated broadcast address and receiving the MU-MIMO frame from the AP.
