1. A station (STA) comprising:
a processor; and
a transceiver;
the processor and the transceiver configured to receive, from an access point (AP), a request-to-send (RTS) frame including:
a receive address (RA) field indicating a broadcast address, and
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 including information indicative of a designation of a plurality of STAs, the plurality of STAs including the STA,
wherein the RTS frame solicits response frames from at least the designated plurality of STAs;
the processor and the transceiver configured to transmit a response frame to the broadcast address indicated by the RA of the RTS frame; and
the processor and the transceiver configured to receive the MU-MIMO frame from the AP.
